# API changelog
 | 
						||
 | 
						||
This page documents changes to the Zulip Server API over time. See
 | 
						||
also the [Zulip release lifecycle][release-lifecycle] for background
 | 
						||
on why this API changelog is important, and the [Zulip server
 | 
						||
changelog][server-changelog].
 | 
						||
 | 
						||
The API feature levels system used in this changelog is designed to
 | 
						||
make it possible to write API clients, such as the Zulip mobile and
 | 
						||
terminal apps, that work with a wide range of Zulip server
 | 
						||
versions. Every change to the Zulip API is recorded briefly here and
 | 
						||
with full details in **Changes** entries in the API documentation for
 | 
						||
the modified endpoint(s).
 | 
						||
 | 
						||
When using an API endpoint whose behavior has changed, Zulip API
 | 
						||
clients should check the `zulip_feature_level` field, present in the
 | 
						||
[`GET /server_settings`](/api/get-server-settings) and [`POST
 | 
						||
/register`](/api/register-queue) responses, to determine the API
 | 
						||
format used by the Zulip server that they are interacting with.
 | 
						||
 | 
						||
## Changes in Zulip 11.0
 | 
						||
 | 
						||
**Feature level 420**
 | 
						||
 | 
						||
* [`POST /mobile_push/e2ee/test_notification`](/api/e2ee-test-notify):
 | 
						||
  Added a new endpoint to send an end-to-end encrypted test push notification
 | 
						||
  to the user's selected mobile device or all of their mobile devices.
 | 
						||
 | 
						||
**Feature level 419**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added `simplified_presence_events`
 | 
						||
  [client capability](/api/register-queue#parameter-client_capabilities),
 | 
						||
  which allows clients to specify whether they support receiving the
 | 
						||
  `presence` event type with user presence data in the modern API format.
 | 
						||
* [`GET /events`](/api/get-events): Added the `presences` field to the
 | 
						||
  `presence` event type for clients that support the `simplified_presence_events`
 | 
						||
  [client capability](/api/register-queue#parameter-client_capabilities).
 | 
						||
  The `presences` field will have the user presence data in the modern
 | 
						||
  API format. For clients that don't support that client capability the
 | 
						||
  event will contain fields with the legacy format for user presence data.
 | 
						||
 | 
						||
**Feature level 418**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): An event with `type: "channel_folder"`
 | 
						||
  and `op: "reorder"` is sent when channel folders are reordered.
 | 
						||
 | 
						||
**Feature level 417**
 | 
						||
 | 
						||
* [`POST channels/create`](/api/create-channel): Added a dedicated
 | 
						||
  endpoint for creating a new channel. Previously, channel creation
 | 
						||
  was done entirely through
 | 
						||
  [`POST /users/me/subscriptions`](/api/subscribe).
 | 
						||
 | 
						||
**Feature level 416**
 | 
						||
 | 
						||
* [`POST /invites`](/api/send-invites), [`POST
 | 
						||
  /invites/multiuse`](/api/create-invite-link): Added a new parameter
 | 
						||
  `welcome_message_custom_text` which allows the users to add a
 | 
						||
  Welcome Bot custom message for new users through invitations.
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`POST /events`](/api/get-events),
 | 
						||
  `PATCH /realm`: Added `welcome_message_custom_text` realm setting which is the
 | 
						||
  default custom message for the Welcome Bot when sending invitations to new users.
 | 
						||
 | 
						||
* [`POST /realm/test_welcome_bot_custom_message`](/api/test-welcome-bot-custom-message):
 | 
						||
  Added new endpoint test messages with the Welcome Bot custom message. The test
 | 
						||
  messages are sent to the acting administrator, allowing them to preview how the
 | 
						||
  custom welcome message will appear to new users upon joining the organization.
 | 
						||
 | 
						||
**Feature level 415**
 | 
						||
 | 
						||
* [`POST /reminders`](/api/create-message-reminder): Added parameter
 | 
						||
  `note` to allow users to add notes to their reminders.
 | 
						||
* [`POST /register`](/api/register-queue): Added `max_reminder_note_length`
 | 
						||
  for clients to restrict the reminder note length before sending it to
 | 
						||
  the server.
 | 
						||
 | 
						||
**Feature level 414**
 | 
						||
 | 
						||
* [`POST /channel_folders/create`](/api/create-channel-folder),
 | 
						||
  [`GET /channel_folders`](/api/get-channel-folders),
 | 
						||
  [`PATCH /channel_folders/{channel_folder_id}`](/api/update-channel-folder):
 | 
						||
  Added a new field `order` to show in which order should channel folders be
 | 
						||
  displayed. The list is 0-indexed and works similar to the `order` field of
 | 
						||
  custom profile fields.
 | 
						||
* [`PATCH /channel_folders`](/api/patch-channel-folders): Added a new
 | 
						||
  endpoint for reordering channel folders. It accepts an array of channel
 | 
						||
  folder IDs arranged in the order the user desires it to be in.
 | 
						||
* [`GET /channel_folders`](/api/get-channel-folders): Channel folders will
 | 
						||
  be ordered by the `order` field instead of `id` field when being returned.
 | 
						||
 | 
						||
**Feature level 413**
 | 
						||

						||

 | 
						||

 | 
						||
  [`GET /users/me/subscriptions`](/api/get-subscriptions):

						||

 | 
						||

						||
* `PATCH /bots/{bot_user_id}`: Previously, changing the owner of a bot
 | 
						||
  unsubscribed the bot from any channels that the new owner was not

  sensitive channel content.

						||
  [`DELETE /streams/{stream_id}`](/api/archive-stream): Channel and

  without having content access to it.

						||
* [`GET /events`](/api/get-events): All users with metadata access to
 |

  a channel are now notified when a relevant stream event occurs.

						||
 | 
						||
**Feature level 338**

						||
 | 
						||

 | 
						||
  deprecated, having been replaced by `can_send_message_group`. Notably,
 | 
						||
  this backwards-compatible `stream_post_policy` value now contains the

  superset of the true value that best approximates the actual permission
 | 
						||
  setting.

 | 
						||
  [`PATCH /streams/{stream_id}`](/api/update-stream): Removed

 | 
						||
  profile time zone differs from the current time displayed by the time
 | 
						||
  zone configured on their device.
 | 
						||
 | 
						||
**Feature level 328**
 | 
						||

  [`GET /events`](/api/get-events): Anonymous groups are now accepted
 | 
						||
  by `can_access_all_users_group` realm setting, which is a now a
 | 
						||
  [group-setting value](/api/group-setting-values) instead of an
 | 
						||
  integer ID of the group.
 | 
						||
 | 
						||
**Feature level 313**
 | 
						||
 | 
						||
* [`PATCH /users/{user_id}`](/api/update-user): Added `new_email` field to
 | 
						||
  allow updating the email address of the target user. The requester must be
 | 
						||
  an organization administrator and have the `can_change_user_emails` special
 | 
						||
  permission.
 | 
						||
* [`PATCH /users/{email}`](/api/update-user-by-email): Added new endpoint,
 | 
						||
  which is a copy of [`PATCH /users/{user_id}`](/api/update-user), but the user
 | 
						||
  is specified by their email address, following the same rules as [`GET
 | 
						||
  /users/{email}`](/api/get-user-by-email).
 | 
						||
 | 
						||
**Feature level 312**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Added `realm_export_consent` event
 | 
						||
  type to allow realm administrators to view which users have
 |

  consented to export their private data as part of a realm export.
 | 
						||
 | 
						||
**Feature level 311**
 | 
						||
 | 
						||
* [`POST /user_groups/{user_group_id}/members`](/api/update-user-group-members):

 | 
						||
  [`POST /register`](/api/register-queue):
 | 
						||
  Added `can_move_messages_between_channels_group` realm setting which is a
 | 
						||
  [group-setting value](/api/group-setting-values) describing the set of users
 | 
						||
  with permission to move messages from one channel to another in the organization.
 | 
						||
* `PATCH /realm`, [`GET /events`](/api/get-events): Removed
 | 
						||
  `move_messages_between_streams_policy` property, as the permission to move
 | 
						||
  messages between channels in the organization is now controlled by
 | 
						||
  `can_move_messages_between_channels_group` setting.
 | 
						||
 | 
						||
**Feature level 309**
 | 
						||
 | 
						||
* [Group-setting values](/api/group-setting-values): Starting with
 | 
						||
  this feature level, it's now possible to use group-setting values in
 | 
						||
  production for those settings whose value is not required to be a
 | 
						||
  system group
 | 
						||
 | 
						||
**Feature level 308**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events),
 | 
						||

						||
  user group objects.
 | 
						||
* [`POST /user_groups/create`](/api/create-user-group): Added `can_leave_group`
 | 
						||
  parameter to support setting the user group whose members can leave the user
 | 
						||
  group.
 | 
						||
* [`PATCH /user_groups/{user_group_id}`](/api/update-user-group): Added
 | 
						||
  `can_leave_group` parameter to support changing the user group whose
 | 
						||
  members can leave the specified user group.
 | 
						||
 | 
						||
**Feature level 307**
 | 
						||
 | 
						||
* `PATCH /realm`, [`GET /events`](/api/get-events),
 | 
						||
  [`POST /register`](/api/register-queue):
 | 
						||
  Added `can_add_custom_emoji_group` realm setting which is a
 | 
						||
  [group-setting value](/api/group-setting-values) describing the set of users
 | 
						||
  with permission to add custom emoji in the organization.
 | 
						||
* `PATCH /realm`, [`GET /events`](/api/get-events): Removed
 | 
						||
  `add_custom_emoji_policy` property, as the permission to add custom emoji
 | 
						||
  in the organization is now controlled by `can_add_custom_emoji_group` setting.
 | 
						||
 | 
						||
**Feature level 306**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Removed the `extra_data` optional
 | 
						||
  field from the `realm/update` event format, which was only used for
 | 
						||
  `plan_type` events, with a single `upload_quota` field. Now, we use
 | 
						||
  a standard `realm/update_dict` event to notify clients about changes
 | 
						||
  in `plan_type` and other fields that atomically change with a given
 | 
						||
  change in plan.
 | 
						||
* [`GET /events`](/api/get-events): Added `max_file_upload_size_mib`
 | 
						||
  field to the `data` object in `realm/update_dict` event format;
 | 
						||
  previously, this was a constant. Note that the field does not have a
 | 
						||
  `realm_` prefix in the [`POST /register`](/api/register-queue)
 | 
						||
  response.
 | 
						||
 | 
						||
**Feature level 305**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events),
 | 
						||
  [`GET /user_groups`](/api/get-user-groups): Add `can_add_members_group` to
 | 
						||
  user group objects.
 | 
						||
* [`POST /user_groups/create`](/api/create-user-group): Added `can_add_members_group`
 | 
						||
  parameter to support setting the user group which can add members to the user
 | 
						||
  group.
 | 
						||
* [`PATCH /user_groups/{user_group_id}`](/api/update-user-group): Added
 | 
						||
  `can_add_members_group` parameter to support changing the user group which
 | 
						||
  can add members to the specified user group.
 | 
						||
* The `can_manage_all_groups` permission now has the natural semantics
 | 
						||
  of applying to all groups, regardless of the role of the user given
 | 
						||
  this permission. Since its introduction in feature level 299,
 | 
						||
  `can_manage_all_groups` had temporarily had unusual semantics
 | 
						||
  matching those of the original`user_group_edit_policy` setting.
 | 
						||
 | 
						||
**Feature level 304**
 | 
						||
 | 
						||
* [`GET /export/realm`](/api/get-realm-exports),
 | 
						||
  [`GET /events`](/api/get-events): Added `export_type` field
 | 
						||
  to the dictionaries in `exports` array. It indicates whether
 | 
						||

 | 
						||
  (standard export).
 | 
						||
 | 
						||
* [`POST /export/realm`](/api/get-realm-exports): Added `export_type`
 | 
						||
  parameter to add support for admins to decide whether to create a
 | 
						||
  public or a standard data export.
 | 
						||
 | 
						||
**Feature level 303**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /user_groups`](/api/get-user-groups),
 | 
						||
  [`GET /user_groups/{user_group_id}/members/{user_id}`](/api/get-is-user-group-member),
 | 
						||
  [`GET /user_groups/{user_group_id}/members`](/api/get-user-group-members):
 | 
						||
  Deactivated users are no longer returned as members of the user groups
 | 
						||
  that they were members of prior to deactivation.
 | 
						||
* [`POST /register`](/api/register-queue): Settings, represented as
 | 
						||
  [group-setting value](/api/group-setting-values), will never include
 | 
						||
  deactivated users in the `direct_members` list for settings whose
 | 
						||
  value is an anonymous group.
 | 
						||
* [`POST /user_groups/{user_group_id}/members`](/api/update-user-group-members):
 | 
						||
  Deactivated users cannot be added or removed from a user group; they
 | 
						||
  are now implicitly not members of any groups while deactivated.
 | 
						||
* [`GET /events`](/api/get-events): User reactivation event is not sent
 | 
						||
  to users who cannot access the reactivated user anymore due to a
 | 
						||
  `can_access_all_users_group` policy.
 | 
						||
* [`GET /events`](/api/get-events): The server will now send
 | 
						||
  `user_group` events with the `add_members`/`remove_members`
 | 
						||
  operations as appropriate when deactivating or reactivating a user,
 | 
						||
  to ensure client state correctly reflects groups never containing
 | 
						||
  deactivated users.
 | 
						||
* [`GET /events`](/api/get-events): To ensure that [group-setting
 | 
						||
  values](/api/group-setting-values) are correct, `realm/update_dict`
 | 
						||
  and `user_group/update` events may now be by sent by the server when
 | 
						||
  processing a deactivation/reactivation of a user, to ensure client
 | 
						||
  state correctly reflects the state, given that deactivated users
 | 
						||
  cannot have permissions in an organization.
 | 
						||
 | 
						||
**Feature level 302**
 | 
						||
 | 
						||
* [`GET /users/{email}`](/api/get-user-by-email): Changed the `email`
 | 
						||

						||
  user group objects.

						||
  parameter to support setting the user group whose members can join the user

 | 
						||
  `can_join_group` parameter to support changing the user group whose
 | 
						||
  members can join the specified user group.
 | 
						||
 | 
						||
**Feature level 300**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-message): Added a new message_ids parameter,
 | 
						||
  as an alternative method of specifying which messages to fetch.

 | 
						||
  manage groups in now controlled by `can_manage_all_groups` setting.
 | 
						||
* [`POST /register`](/api/register-queue): `user_group_edit_policy`
 | 
						||
  field is deprecated, having been replaced by `can_create_groups` for user
 | 
						||
  group creation and `can_manage_all_groups` for user group management.
 | 
						||
 | 
						||
**Feature level 298**
 | 
						||
 | 
						||
* [`POST /user_groups/{user_group_id}/deactivate`](/api/deactivate-user-group):
 | 
						||
  Server now returns a specific error response (`"code": CANNOT_DEACTIVATE_GROUP_IN_USE`)
 | 
						||
  when a user group cannot be deactivated because it is in use. The
 | 
						||
  error response contains details about where the user group is being used.
 | 
						||

 | 
						||
  [`GET /realm/profile_fields`](/api/get-custom-profile-fields): Added a new

 | 
						||
* `/api/v1/tus` is an endpoint implementing the [`tus`
 | 
						||
  protocol](https://tus.io/protocols/resumable-upload) for resumable uploads.
 | 
						||
  Clients which send authenticated credentials (either via browser-based
 | 
						||
  cookies, or API key via `Authorization` header) may use this endpoint to
 | 
						||
  create uploads, similar to [`POST /user_uploads`](/api/upload-file).
 | 
						||
 | 
						||
**Feature level 294**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Clients that do not
 |

* [`POST /register`](/api/register-queue): `realm_create_web_public_stream_policy`
 | 
						||
  field is deprecated, having been replaced by `can_create_web_public_channel_group`.
 | 
						||
  Notably, this backwards-compatible `realm_create_web_public_stream_policy` value
 | 
						||
  now contains the superset of the true value that best approximates the actual
 | 
						||
  permission setting.
 | 
						||
 |

Feature level 279 is reserved for future use in 9.x maintenance
 |

releases.

## Changes in Zulip 9.2
 | 
						||
 | 
						||
**Feature level 278**
 | 
						||
 | 
						||
* [Markdown message
 | 
						||
  formatting](/api/message-formatting#image-previews): Added
 | 
						||
  `data-original-dimensions` attributes to placeholder images
 | 
						||
  (`image-loading-placeholder`), containing the dimensions of the
 | 
						||
  original image. Backported change from feature level 287.
 | 
						||
 | 
						||
## Changes in Zulip 9.0
 | 
						||
 | 
						||
**Feature level 277**
 | 
						||
 | 
						||
No changes; feature level used for Zulip 9.0 release.
 | 
						||
 | 
						||
**Feature level 276**
 | 
						||
 | 
						||
* [Markdown message formatting](/api/message-formatting#image-previews):
 | 
						||
  Image preview elements not contain a `data-original-dimensions`
 | 
						||
  attribute containing the dimensions of the original image.
 | 
						||
 | 
						||
**Feature level 275**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`PATCH
 | 
						||
  /settings`](/api/update-settings), [`PATCH
 | 
						||
  /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults):
 | 
						||
  Added new `web_animate_image_previews` setting, which controls how
 | 
						||
  animated images should be played in the web/desktop app message feed.
 | 
						||
 | 
						||
**Feature level 274**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): `delete_message` events are now
 | 
						||
  always sent to the user who deletes the message, even if the message
 | 
						||
  was in a channel that the user was not subscribed to.
 | 
						||
 | 
						||
**Feature level 273**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added `server_thumbnail_formats`
 | 
						||
  describing what formats the server will thumbnail images into.
 | 
						||
 | 
						||
**Feature level 272**
 | 
						||
 | 
						||
* [`POST /user_uploads`](/api/upload-file): `uri` was renamed
 | 
						||
  to `url`, but remains available as a deprecated alias for
 | 
						||
  backwards-compatibility.
 | 
						||
 | 
						||
**Feature level 271**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-messages),
 | 
						||
  [`GET /messages/matches_narrow`](/api/check-messages-match-narrow),
 | 
						||
  [`POST /messages/flags/narrow`](/api/update-message-flags-for-narrow),
 | 
						||
  [`POST /register`](/api/register-queue):
 | 
						||
  Added support for a new [search/narrow filter](/api/construct-narrow#changes)
 | 
						||
  operator, `with`, which uses a message ID for its operand. It returns
 | 
						||
  messages in the same conversation as the message with the specified
 | 
						||
  ID, and is designed to be used for creating permanent links to topics
 | 
						||
  that continue to work when a topic is moved or resolved.
 | 
						||
 | 
						||
**Feature level 270**
 | 
						||
 | 
						||
* `PATCH /realm`, [`POST /register`](/api/register-queue),
 | 
						||
  [`GET /events`](/api/get-events): Added two new realm settings,
 | 
						||
  `direct_message_initiator_group`, which is a
 | 
						||
  [group-setting value](/api/group-setting-values) describing the
 | 
						||
  set of users with permission to initiate direct message thread, and
 | 
						||
  `direct_message_permission_group`, which is a
 | 
						||
  [group-setting value](/api/group-setting-values) describing the
 | 
						||
  set of users of which at least one member must be included as sender
 | 
						||
  or recipient in all personal and group direct messages.
 | 
						||
  Removed `private_message_policy` property, as the permission to send
 | 
						||
  direct messages is now controlled by `direct_message_initiator_group`
 | 
						||
  and `direct_message_permission_group` settings.
 | 
						||
 | 
						||
**Feature level 269**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`PATCH
 | 
						||
  /settings`](/api/update-settings), [`PATCH
 | 
						||
  /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults):
 | 
						||
  Added new user setting `web_channel_default_view`, controlling the
 | 
						||
  behavior of clicking a channel link in the web/desktop apps.
 | 
						||
 | 
						||
**Feature level 268**
 | 
						||
 | 
						||
* [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults),
 | 
						||
  [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings):
 | 
						||
  Added a new `web_navigate_to_sent_message` setting to allow users to decide
 | 
						||
  whether to automatically go to conversation where they sent a message.
 | 
						||
 | 
						||
**Feature level 267**
 | 
						||
 | 
						||
* [`GET /invites`](/api/get-invites),[`POST /invites`](/api/send-invites): Added
 | 
						||
  `notify_referrer_on_join` parameter, indicating whether the referrer has opted
 | 
						||
  to receive a direct message from the notification bot whenever a user joins
 | 
						||
  via this invitation.
 | 
						||
 | 
						||
**Feature level 266**
 | 
						||
 | 
						||
* `PATCH /realm`, [`POST /register`](/api/register-queue),
 | 
						||
  [`GET /events`](/api/get-events): Added `can_create_private_channel_group`
 | 
						||
  realm setting, which is a [group-setting value](/api/group-setting-values)
 | 
						||
  describing the set of users with permission to create private channels.
 | 
						||
* `PATCH /realm`, [`GET /events`](/api/get-events): Removed
 | 
						||
  `create_private_stream_policy` property, as the permission to create private
 | 
						||
  channels is now controlled by `can_create_private_channel_group` setting.
 | 
						||
* [`POST /register`](/api/register-queue): `realm_create_private_stream_policy`
 | 
						||
  field is deprecated, having been replaced by `can_create_private_channel_group`.
 | 
						||
  Notably, this backwards-compatible `realm_create_private_stream_policy` value
 | 
						||
  now contains the superset of the true value that best approximates the actual
 | 
						||
  permission setting.
 | 
						||
 | 
						||
**Feature level 265**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-messages),
 | 
						||
  [`GET /messages/matches_narrow`](/api/check-messages-match-narrow),
 | 
						||
  [`POST /messages/flags/narrow`](/api/update-message-flags-for-narrow),
 | 
						||
  [`POST /register`](/api/register-queue):
 | 
						||
  Added a new [search/narrow filter](/api/construct-narrow#changes),
 | 
						||
  `is:followed`, matching messages in topics that the current user is
 | 
						||
  [following](/help/follow-a-topic).
 | 
						||
 | 
						||
**Feature level 264**
 | 
						||
 | 
						||
* `PATCH /realm`, [`POST /register`](/api/register-queue),
 | 
						||
  [`GET /events`](/api/get-events): Added `can_create_public_channel_group`
 | 
						||
  realm setting, which is a [group-setting value](/api/group-setting-values)
 | 
						||
  describing the set of users with permission to create channels.
 | 
						||
* `PATCH /realm`, [`GET /events`](/api/get-events): Removed
 | 
						||
  `create_public_stream_policy` property, as the permission to create public
 | 
						||
  channels is now controlled by `can_create_public_channel_group` setting.
 | 
						||
* [`POST /register`](/api/register-queue): `realm_create_public_stream_policy`
 | 
						||
  field is deprecated, having been replaced by `can_create_public_channel_group`.
 | 
						||
  Notably, this backwards-compatible `realm_create_public_stream_policy` value
 | 
						||
  now contains the superset of the true value that best approximates the actual
 | 
						||
  permission setting.
 | 
						||
 | 
						||
**Feature level 263**
 | 
						||
 | 
						||
* [`POST /users/me/presence`](/api/update-presence):
 | 
						||
  A new `last_update_id` parameter can be given, instructing
 | 
						||
  the server to only fetch presence data with `last_update_id`
 | 
						||
  greater than the value provided. The server also provides
 | 
						||
  a `presence_last_update_id` field in the response, which
 | 
						||
  tells the client the greatest `last_update_id` of the fetched
 | 
						||
  presence data. This can then be used as the value in the
 | 
						||
  aforementioned parameter to avoid re-fetching of already known
 | 
						||
  data when polling the endpoint next time.
 | 
						||
  Additionally, the client specifying the `last_update_id`
 | 
						||
  implies it uses the modern API format, so
 | 
						||
  `slim_presence=true` will be assumed by the server.
 | 
						||
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): The response now also
 | 
						||
  includes a `presence_last_update_id` field, with the same
 | 
						||
  meaning as described above for [`/users/me/presence`](/api/update-presence).
 | 
						||
  In the same way, the retrieved value can be passed when
 | 
						||
  querying [`/users/me/presence`](/api/update-presence) to avoid
 | 
						||
  re-fetching of already known data.
 | 
						||
 | 
						||
**Feature level 262**
 | 
						||
 | 
						||
* [`GET /users/{user_id}/status`](/api/get-user-status): Added a new
 | 
						||
  endpoint to fetch an individual user's currently set
 | 
						||
  [status](/help/status-and-availability).
 | 
						||
 | 
						||
**Feature level 261**
 | 
						||
 | 
						||
* [`POST /invites`](/api/send-invites),
 | 
						||
  [`POST /invites/multiuse`](/api/create-invite-link): Added
 | 
						||
  `include_realm_default_subscriptions` parameter to indicate whether
 | 
						||
  the newly created user will be automatically subscribed to [default
 | 
						||
  channels](/help/set-default-channels-for-new-users) in the
 | 
						||
  organization. Previously, the default channel IDs needed to be included
 | 
						||
  in the `stream_ids` parameter. This also allows a newly created user
 | 
						||
  to be automatically subscribed to the default channels in an
 | 
						||
  organization when the user creating the invitation does not generally
 | 
						||
  have permission to [subscribe other users to
 | 
						||
  channels](/help/configure-who-can-invite-to-channels).
 | 
						||
 | 
						||
**Feature level 260**
 | 
						||
 | 
						||
* [`PATCH /user_groups/{user_group_id}`](/api/update-user-group):
 | 
						||
  Updating `can_mention_group` now uses a race-resistant format where
 | 
						||
  the client sends the expected `old` value and desired `new` value.
 | 
						||
 | 
						||
**Feature level 259**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events):
 | 
						||
  For the `onboarding_steps` event type, an array of onboarding steps
 | 
						||
  to be displayed to clients is sent. Onboarding step now has one-time
 | 
						||
  notices as the only valid type. Prior to this, both hotspots and
 | 
						||
  one-time notices were valid types of onboarding steps. There is no compatibility
 | 
						||
  support, as we expect that only official Zulip clients will interact with
 | 
						||
  this data. Currently, no client other than the Zulip web app uses this.
 | 
						||
 | 
						||
**Feature level 258**
 | 
						||
 | 
						||
* [`GET /user_groups`](/api/get-user-groups), [`POST
 | 
						||
  /register`](/api/register-queue): `can_mention_group` field can now
 | 
						||
  either be an ID of a named user group with the permission, or an
 | 
						||
  object describing the set of users and groups with the permission.
 | 
						||
* [`POST /user_groups/create`](/api/create-user-group), [`PATCH
 | 
						||
  /user_groups/{user_group_id}`](/api/update-user-group): The
 | 
						||
  `can_mention_group` parameter can now either be an ID of a named
 | 
						||
  user group or an object describing a set of users and groups.
 | 
						||
 | 
						||
**Feature level 257**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue),
 | 
						||
  [`POST /server_settings`](/api/get-server-settings), `PATCH /realm`:
 | 
						||
  `realm_uri` was renamed to `realm_url`, but remains available as a
 | 
						||
  deprecated alias for backwards-compatibility.
 | 
						||
* Mobile push notification payloads, similarly, have a new `realm_url`,
 | 
						||
  replacing `realm_uri`, which remains available as a deprecated alias
 | 
						||
  for backwards-compatibility.
 | 
						||
 | 
						||
**Feature level 256**
 | 
						||
 | 
						||
* [`POST /streams/{stream_id}/delete_topic`](/api/delete-topic),
 | 
						||
  [`GET /events`](/api/get-events): When messages are deleted, a
 | 
						||
  [`stream` op: `update`](/api/get-events#stream-update) event with
 | 
						||
  an updated value for `first_message_id` may now be sent to clients.
 | 
						||
 | 
						||
**Feature level 255**
 | 
						||
 | 
						||
* "Stream" was renamed to "Channel" across strings in the Zulip API
 | 
						||
  and UI. Clients supporting a range of server versions are encouraged
 | 
						||
  to use different strings based on the server's API feature level for
 | 
						||
  consistency. Note that feature level marks the strings transition
 | 
						||
  only: Actual API changes related to this transition have their own
 | 
						||
  API changelog entries.
 | 
						||
 | 
						||
**Feature level 254**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events),
 | 
						||
  [`GET /streams`](/api/get-streams),
 | 
						||
  [`GET /streams/{stream_id}`](/api/get-stream-by-id),
 | 
						||
  [`GET /users/me/subscriptions`](/api/get-subscriptions): Added a new
 | 
						||
  field `creator_id` to stream and subscription objects, which contains the
 | 
						||
  user ID of the stream's creator.
 | 
						||
 | 
						||
**Feature level 253**
 | 
						||
 | 
						||
* [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults),
 | 
						||
  [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings):
 | 
						||
  Added new `receives_typing_notifications` option to allow users to decide whether
 | 
						||
  to receive typing notification events from other users.
 | 
						||
 | 
						||
**Feature level 252**
 | 
						||
 | 
						||
* `PATCH /realm/profile_fields/{field_id}`: `name`, `hint`, `display_in_profile_summary`,
 | 
						||
  `required` and `field_data` fields are now optional during an update. Previously we
 | 
						||
  required the clients to populate the fields in the PATCH request even if there was
 | 
						||
  no change to those fields' values.
 | 
						||
 | 
						||
**Feature level 251**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Fixed `realm_upload_quota_mib`
 | 
						||
  value to actually be in MiB. Until now the value was in bytes.
 | 
						||
 | 
						||
**Feature level 250**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-messages),
 | 
						||
  [`GET /messages/matches_narrow`](/api/check-messages-match-narrow),
 | 
						||
  [`POST /messages/flags/narrow`](/api/update-message-flags-for-narrow),
 | 
						||
  [`POST /register`](/api/register-queue):
 | 
						||
  Added support for two [search/narrow filters](/api/construct-narrow#changes)
 | 
						||
  related to stream messages: `channel` and `channels`. The `channel`
 | 
						||
  operator is an alias for the `stream` operator. The `channels`
 | 
						||
  operator is an alias for the `streams` operator.
 | 
						||
 | 
						||
**Feature level 249**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-messages),

						||
  [`POST /messages/flags/narrow`](/api/update-message-flags-for-narrow),
 | 
						||
  [`POST /register`](/api/register-queue):
 | 
						||
  Added support for a new [search/narrow filter](/api/construct-narrow#changes),
 | 
						||
  `has:reaction`, which returns messages with at least one [emoji
 | 
						||
  reaction](/help/emoji-reactions).
 | 
						||
 | 
						||
**Feature level 248**
 | 
						||
 | 
						||
* [`POST /typing`](/api/set-typing-status), [`POST /messages`](/api/send-message),
 | 
						||
  [`POST /scheduled_messages`](/api/create-scheduled-message),
 | 
						||
  [`PATCH /scheduled_messages/<int:scheduled_message_id>`](/api/update-scheduled-message):
 | 
						||
  Added `"channel"` as an additional value for the `type` parameter to
 | 
						||
  indicate a stream message.
 | 
						||
 | 
						||
**Feature level 247**
 | 
						||
 | 
						||
* [Markdown message formatting](/api/message-formatting#mentions-and-silent-mentions):
 | 
						||
  Added `channel` to the supported options for [wildcard
 | 
						||
  mentions](/help/mention-a-user-or-group#mention-everyone-on-a-stream).

						||
 | 
						||

 | 
						||
  /events`](/api/get-events): Added new `require_unique_names` setting

 | 
						||
  /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults)
 | 
						||
  [`POST /register`](/api/register-queue), [`GET
 | 
						||
  /events`](/api/get-events), [`PATCH
 | 
						||
  /settings`](/api/update-settings): Added new `web_font_size_px` and
 | 
						||
  `web_line_height_percent` settings to allow users to control the
 | 
						||
  styling of the web application.
 | 
						||
 | 
						||
**Feature level 244**
 | 
						||
 | 
						||

 | 
						||
  [`GET /realm/profile_fields`](/api/get-custom-profile-fields): Added a new
 | 
						||
  parameter `required`, on custom profile field objects, indicating whether an
 | 
						||
  organization administrator has configured the field as something users should
 | 
						||
  be required to provide.
 | 
						||
 | 
						||
**Feature level 243**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET
 | 
						||
  /events`](/api/get-events): Changed the format of
 | 
						||
  `realm_authentication_methods` and `authentication_methods`,
 | 
						||
  respectively, to use a dictionary rather than a boolean as the value
 | 
						||
  for each authentication method. The new dictionaries are more
 | 
						||
  extensively and contain fields indicating whether the backend is
 | 
						||
  unavailable to the current realm due to Zulip Cloud plan
 | 
						||
  restrictions or any other reason.
 | 
						||
 | 
						||
**Feature level 242**

 | 
						||
  `PATCH /realm`: Added `zulip_update_announcements_stream_id` realm setting,

**Feature level 241**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`POST /events`](/api/get-events),

 | 
						||
  `signup_notifications_stream` to `new_stream_announcements_stream` and
 | 
						||
  `signup_announcements_stream`, respectively.
 | 
						||
 | 
						||
**Feature level 240**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): The `restart` event no longer contains an
 | 
						||
  optional `immediate` flag.
 | 
						||
* [`GET /events`](/api/get-events): A new `web_reload_client` event has been
 | 
						||
  added; it is used to signal to website-based clients that they should reload
 | 
						||
  their code.  This was previously implied by the `restart` event.
 | 
						||
 | 
						||
Feature levels 238-239 are reserved for future use in 8.x maintenance
 | 
						||
releases.
 | 
						||
 | 
						||
## Changes in Zulip 8.0
 | 
						||
 | 
						||
**Feature level 237**

No changes; feature level used for Zulip 8.0 release.
 | 
						||
 | 
						||
**Feature level 236**
 | 
						||
 | 
						||
* [`POST /messages`](/api/send-message), [`POST
 | 
						||
  /scheduled_messages`](/api/create-scheduled-message): The new
 | 
						||
  `read_by_sender` parameter lets the client override the heuristic
 | 
						||
  that determines whether the new message will be initially marked
 | 
						||
  read by its sender.
 | 
						||
 | 
						||
**Feature level 235**
 | 
						||
 | 
						||
* [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults),
 | 
						||
  [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings):

						||
 | 
						||
**Feature level 234**
 | 
						||
 | 
						||
* Mobile push notifications now include a `realm_name` field.
 | 
						||
* [`POST /mobile_push/test_notification`](/api/test-notify) now sends
 | 
						||
  a test notification with `test` rather than `test-by-device-token`
 | 
						||
  in the `event` field.
 | 
						||
 | 
						||
**Feature level 233**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events):
 | 
						||
  Renamed the `hotspots` event type and the related `hotspots` object array
 | 
						||
  to `onboarding_steps`. These are sent to clients if there are onboarding
 | 
						||
  steps to display to the user. Onboarding steps now include
 | 
						||
  both hotspots and one-time notices. Prior to this, hotspots were the only
 | 
						||
  type of onboarding step. Also, added a `type` field to the objects
 | 
						||
  returned in the renamed `onboarding_steps` array to distinguish between
 | 
						||
  the two types of onboarding steps.
 | 
						||
 | 
						||
* `POST /users/me/onboarding_steps`: Added a new endpoint, which
 | 
						||
  deprecates the `/users/me/hotspots` endpoint, in order to support
 | 
						||
  displaying both one-time notices (which highlight new features for
 | 
						||
  existing users) and hotspots (which are used in new user tutorials).
 | 
						||
  This endpoint marks both types of onboarding steps, i.e. `hotspot`
 | 
						||
  and `one_time_notice`, as read by the user. There is no compatibility
 | 
						||
  support for `/users/me/hotspots` as no client other than the Zulip
 | 
						||
  web app used the endpoint prior to these changes.
 | 
						||
 | 
						||
**Feature level 232**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added a new
 | 
						||
  `user_list_incomplete` [client
 | 
						||
  capability](/api/register-queue#parameter-client_capabilities)
 | 
						||
  controlling whether `realm_users` contains "Unknown user"
 | 
						||
  placeholder objects for users that the current user cannot access
 | 
						||
  due to a `can_access_all_users_group` policy.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): The new `user_list_incomplete`
 | 
						||
  [client
 | 
						||
  capability](/api/register-queue#parameter-client_capabilities)
 | 
						||
  controls whether to send `realm_user` events with `op: "add"`
 | 
						||
  containing "Unknown user" placeholder objects to clients when a new
 | 
						||
  user is created that the client does not have access to due to a
 | 
						||
  `can_access_all_users_group` policy.
 | 
						||
 | 
						||
**Feature level 231**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue):
 | 
						||
  `realm_push_notifications_enabled` now represents more accurately
 | 
						||
  whether push notifications are actually enabled via the mobile push
 | 
						||
  notifications service. Added
 | 
						||
  `realm_push_notifications_enabled_end_timestamp` field to realm
 | 
						||
  data.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): A `realm` update event is now sent
 | 
						||
  whenever `push_notifications_enabled` or
 | 
						||
  `push_notifications_enabled_end_timestamp` changes.
 | 
						||
 | 
						||
**Feature level 230**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events):
 | 
						||
  Added `has_trigger` field to objects returned in the `hotspots` array to
 | 
						||
  identify if the hotspot will activate only when some specific event
 | 
						||
  occurs.
 | 
						||
 | 
						||
**Feature level 229**
 | 
						||
 | 
						||
* [`PATCH /messages/{message_id}`](/api/update-message), [`POST
 | 
						||
  /messages`](/api/send-message): Topic wildcard mentions involving
 | 
						||
  large numbers of participants are now restricted by
 | 
						||
  `wildcard_mention_policy`. The server now uses the
 | 
						||
  `STREAM_WILDCARD_MENTION_NOT_ALLOWED` and
 | 
						||
  `TOPIC_WILDCARD_MENTION_NOT_ALLOWED` error codes when a message is
 | 
						||
  rejected because of `wildcard_mention_policy`.
 | 
						||
 | 
						||
**Feature level 228**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): `realm_user` events with `op: "update"`
 | 
						||
  are now only sent to users who can access the modified user.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): `presence` events are now only sent to
 | 
						||
  users who can access the user who comes back online if the
 | 
						||
  `CAN_ACCESS_ALL_USERS_GROUP_LIMITS_PRESENCE` server setting is set
 | 
						||
  to `true`.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): `user_status` events are now only
 | 
						||
  sent to users who can access the modified user.
 | 
						||
 | 
						||
* [`GET /realm/presence`](/api/get-presence): The endpoint now returns
 | 
						||
  presence information of accessible users only if the
 | 
						||
  `CAN_ACCESS_ALL_USERS_GROUP_LIMITS_PRESENCE` server setting is set
 | 
						||
  to `true`.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): `realm_user` events with `op: "add"`
 | 
						||
  are now also sent when a guest user gains access to a user.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): `realm_user` events with `op: "remove"`
 | 
						||
  are now also sent when a guest user loses access to a user.
 | 
						||
 | 
						||
**Feature level 227**
 | 
						||
 | 
						||
* [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults),
 | 
						||
  [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings):
 | 
						||
  Added `DMs, mentions, and followed topics` option for `desktop_icon_count_display`
 | 
						||
  setting, and renumbered the options.
 | 
						||
  The total unread count of DMs, mentions, and followed topics appears in
 | 
						||
  desktop sidebar and browser tab when this option is configured.
 | 
						||
 | 
						||
**Feature level 226**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events),
 | 
						||
  [`GET /users/me/subscriptions`](/api/get-subscriptions): Removed
 | 
						||
  `email_address` field from subscription objects.
 | 
						||
 | 
						||
* [`GET /streams/{stream_id}/email_address`](/api/get-stream-email-address):
 | 
						||
  Added new endpoint to get email address of a stream.
 | 
						||
 | 
						||
**Feature level 225**
 | 
						||
 | 
						||
* `PATCH /realm`, [`POST /register`](/api/register-queue),
 | 
						||
  [`GET /events`](/api/get-events): Added `can_access_all_users_group_id`
 | 
						||
  realm setting, which is the ID of the user group whose members can
 | 
						||
  access all the users in the organization.
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added `allowed_system_groups`
 | 
						||
  field to configuration data object of permission settings passed in
 | 
						||
  `server_supported_permission_settings`.
 | 
						||
 | 
						||
**Feature level 224**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events), [`GET /messages`](/api/get-messages),
 | 
						||
  [`GET /messages/{message_id}`](/api/get-message): Of the [available
 | 
						||
  message flags](/api/update-message-flags#available-flags) that a user
 | 
						||
  may have for a message, the `wildcard_mentioned` flag was
 | 
						||
  deprecated in favor of the `stream_wildcard_mentioned` and
 | 
						||
  `topic_wildcard_mentioned` flags, but it is still available for
 | 
						||
  backwards compatibility.
 | 
						||
 | 
						||
**Feature level 223**
 | 
						||
 | 
						||
* [`POST /users/me/apns_device_token`](/api/add-apns-token):
 | 
						||
  The `appid` parameter is now required.
 | 
						||
  Previously it defaulted to the server setting `ZULIP_IOS_APP_ID`,
 | 
						||
  defaulting to "org.zulip.Zulip".
 | 
						||
 | 
						||
* `POST /remotes/server/register`: The `ios_app_id` parameter is now
 | 
						||
  required when `kind` is 1, i.e. when registering an APNs token.
 | 
						||
  Previously it was ignored, and the push bouncer effectively
 | 
						||
  assumed its value was the server setting `APNS_TOPIC`,
 | 
						||
  defaulting to "org.zulip.Zulip".
 | 
						||
 | 
						||
**Feature level 222**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): When a user is deactivated or
 | 
						||
  reactivated, the server uses `realm_user` events with `op: "update"`
 | 
						||
  updating the `is_active` field, instead of `realm_user` events with
 | 
						||
  `op: "remove"` and `op: "add"`, respectively.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): When a bot is deactivated or
 | 
						||
  reactivated, the server sends `realm_bot` events with `op: "update"`
 | 
						||
  updating the `is_active` field, instead of `realm_bot` events with
 | 
						||
  `op: "remove"` and `op: "add"`, respectively.
 | 
						||
 | 
						||
**Feature level 221**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added `server_supported_permission_settings`
 | 
						||
  field in the response which contains configuration data for various permission
 | 
						||
  settings.
 | 
						||
 | 
						||
**Feature level 220**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Stream creation events for web-public
 | 
						||
  streams are now sent to all guest users in the organization as well.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): The `subscription` events for `op:
 | 
						||
  "peer_add"` and `op: "peer_remove"` are now sent to subscribed guest
 | 
						||
  users for public streams and to all the guest users for web-public
 | 
						||
  streams; previously, they incorrectly only received these for
 | 
						||
  private streams.
 | 
						||
 | 
						||
**Feature level 219**
 | 
						||
 | 
						||
* [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults)
 | 
						||
  [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events),
 | 
						||
  [`PATCH /settings`](/api/update-settings): Renamed `default_view` and
 | 
						||
  `escape_navigates_to_default_view` settings to `web_home_view` and
 | 
						||
  `web_escape_navigates_to_home_view` respectively.
 | 
						||
* [`POST /user_topics`](/api/update-user-topic), [`POST
 | 
						||
  register`](/api/register-queue), [`GET /events`](/api/get-events):
 | 
						||
  Added followed as a supported value for visibility policies in
 | 
						||
  `user_topic` objects.
 | 
						||
 | 
						||
**Feature level 218**
 | 
						||
 | 
						||
* [`POST /messages`](/api/send-message): Added an optional
 | 
						||
  `automatic_new_visibility_policy` enum field in the success response
 | 
						||
  to indicate the new visibility policy value due to the [visibility policy settings](/help/mute-a-topic)
 | 
						||
  during the send message action.
 | 
						||
 | 
						||
**Feature level 217**
 | 
						||
 | 
						||
* [`POST /mobile_push/test_notification`](/api/test-notify): Added new endpoint
 | 
						||
  to send a test push notification to a mobile device or devices.
 | 
						||
 | 
						||
**Feature level 216**
 | 
						||
 | 
						||
* `PATCH /realm`, [`POST register`](/api/register-queue),
 | 
						||
  [`GET /events`](/api/get-events): Added `enable_guest_user_indicator`
 | 
						||
  setting to control whether "(guest)" is added to user names in UI.
 | 
						||
 | 
						||
**Feature level 215**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Replaced the value `private`
 | 
						||
  with `direct` in the `message_type` field for the `typing` events
 | 
						||
  sent when a user starts or stops typing a message.
 | 
						||
 | 
						||
* [`POST /typing`](/api/set-typing-status): Stopped supporting `private`
 | 
						||
  as a valid value for the `type` parameter.
 | 
						||
 | 
						||
* [`POST /typing`](/api/set-typing-status): Stopped using the `to` parameter
 | 
						||
  for the `"stream"` type. Previously, in the case of the `"stream"` type, it
 | 
						||
  accepted a single-element list containing the ID of the stream. Added an
 | 
						||
  optional parameter, `stream_id`. Now, `to` is used only for `"direct"` type.
 | 
						||
  In the case of `"stream"` type, `stream_id` and `topic` are used.
 | 
						||
 | 
						||
* Note that stream typing notifications were not enabled in any Zulip client
 | 
						||
  prior to feature level 215.
 | 
						||
 | 
						||
**Feature level 214**
 | 
						||
 | 
						||
* [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults),
 | 
						||
  [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings):
 | 
						||
  Added two new user settings, `automatically_follow_topics_policy` and
 | 
						||
  `automatically_unmute_topics_in_muted_streams_policy`. The settings control the
 | 
						||
  user's preference on which topics the user will automatically 'follow' and
 | 
						||
  'unmute in muted streams' respectively.
 | 
						||
 | 
						||
**Feature level 213**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Fixed incorrect handling of
 | 
						||
  unmuted and followed topics in calculating the `mentions` and
 | 
						||
  `count` fields of the `unread_msgs` object.
 | 
						||
 | 
						||
**Feature level 212**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events), [`POST /register`](/api/register-queue),
 | 
						||
  `PATCH /realm`: Added the `jitsi_server_url` field to the `realm` object,
 | 
						||
  allowing organizations to set a custom Jitsi Meet server. Previously, this
 | 
						||
  was only available as a server-level configuration.
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added `server_jitsi_server_url`
 | 
						||
  fields to the `realm` object. The existing `jitsi_server_url` will now be
 | 
						||
  calculated as `realm_jitsi_server_url || server_jitsi_server_url`.
 | 
						||
 | 
						||
**Feature level 211**
 | 
						||
 | 
						||
* [`POST /streams/{stream_id}/delete_topic`](/api/delete-topic),
 | 
						||
  [`POST /mark_all_as_read`](/api/mark-all-as-read):
 | 
						||
  Added a `complete` boolean field in the success response to indicate
 | 
						||
  whether all or only some of the targeted messages were processed.
 | 
						||
  This replaces the use of `"result": "partially_completed"` (introduced
 | 
						||
  in feature levels 154 and 153), so that these endpoints now send a
 | 
						||
  `result` string of either `"success"` or `"error"`, like the rest of
 | 
						||
  the Zulip API.
 | 
						||
 | 
						||
**Feature level 210**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings),
 | 
						||
  [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults):
 | 
						||
  Added new `web_stream_unreads_count_display_policy` display setting, which controls in
 | 
						||
  which streams (all/unmuted/none) unread messages count shows up
 | 
						||
  in left sidebar.
 | 
						||
 | 
						||
**Feature level 209**
 | 
						||
 | 
						||
* `PATCH /realm`, [`POST /register`](/api/register-queue),
 | 
						||
  [`GET /events`](/api/get-events): Added `create_multiuse_invite_group`
 | 
						||
  realm setting, which is the ID of the user group whose members can
 | 
						||
  create [reusable invitation links](/help/invite-new-users#create-a-reusable-invitation-link)
 | 
						||
  to an organization. Previously, only admin users could create these
 | 
						||
  links.
 | 
						||
 | 
						||
* [`POST /invites/multiuse`](/api/create-invite-link): Non-admin users can
 | 
						||
  now use this endpoint to create reusable invitation links. Previously,
 | 
						||
  this endpoint was restricted to admin users only.
 | 
						||
 | 
						||
* [`GET /invites`](/api/get-invites): Endpoint response for non-admin users now
 | 
						||
  includes both email invitations and reusable invitation links that they have
 | 
						||
  created. Previously, non-admin users could only create email invitations, and
 | 
						||
  therefore the response did not include reusable invitation links for these
 | 
						||
  users.
 | 
						||
 | 
						||
* [`DELETE /invites/multiuse/{invite_id}`](/api/revoke-invite-link): Non-admin
 | 
						||
  users can now revoke reusable invitation links they have created. Previously,
 | 
						||
  only admin users could create and revoke reusable invitation links.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): When the set of invitations in an
 | 
						||
  organization changes, an `invites_changed` event is now sent to the
 | 
						||
  creator of the changed invitation, as well as all admin users.
 | 
						||
  Previously, this event was only sent to admin users.
 | 
						||
 | 
						||
**Feature level 208**
 | 
						||
 | 
						||
* [`POST /users/me/subscriptions`](/api/subscribe),
 | 
						||
  [`DELETE /users/me/subscriptions`](/api/unsubscribe): These endpoints
 | 
						||
  now return an HTTP status code of 400 with `code: "BAD_REQUEST"` in
 | 
						||
  the error response when a user specified in the `principals` parameter
 | 
						||
  is deactivated or does not exist. Previously, these endpoints returned
 | 
						||
  an HTTP status code of 403 with `code: "UNAUTHORIZED_PRINCIPAL"` in the
 | 
						||
  error response for these cases.
 | 
						||
 | 
						||
**Feature level 207**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added `display_name` and
 | 
						||
  `all_event_types` fields to the `realm_incoming_webhook_bots` object.

 | 
						||
 | 
						||

 | 
						||
  controlling whether to request a Zoom meeting that defaults to
 | 
						||
  having video enabled.
 | 
						||
 | 
						||
**Feature level 205**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): `streams` field in the response
 | 
						||
  now includes [web-public streams](/help/public-access-option) as well.
 | 
						||
* [`GET /events`](/api/get-events): Events for stream creation and deletion
 | 
						||
  are now sent to clients when a user gains or loses access to any streams
 | 
						||
  due to a change in their [role](/help/user-roles).
 | 
						||
* [`GET /events`](/api/get-events): The `subscription` events for `op:
 | 
						||
  "peer_add"` are now sent to clients when a user gains access to a stream
 | 
						||
  due to a change in their role.
 | 
						||
 | 
						||
**Feature level 204**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added
 | 
						||
  `server_typing_started_wait_period_milliseconds`,
 | 
						||
  `server_typing_stopped_wait_period_milliseconds`, and
 | 
						||
  `server_typing_started_expiry_period_milliseconds` fields
 | 
						||
  for clients to use when implementing [typing
 | 
						||
  notifications](/api/set-typing-status) protocol.

**Feature level 201**
 | 
						||
 | 
						||
* `POST /zulip-outgoing-webhook`: Renamed the notification trigger
 | 
						||
  `private_message` to `direct_message`.

 | 
						||
**Feature level 200**
 | 
						||
 | 
						||
* [`PATCH /streams/{stream_id}`](/api/update-stream): Added
 | 
						||
  `is_default_stream` parameter to change whether the stream is a
 | 
						||
  default stream for new users in the organization.
 | 
						||
* [`POST /users/me/subscriptions`](/api/subscribe): Added
 | 
						||
  `is_default_stream` parameter which determines whether any streams
 |

  [`PATCH /streams/{stream_id}`](/api/update-stream),
 | 
						||
  [`GET /users/me/subscriptions`](/api/get-subscriptions),
 | 
						||
  [`GET /streams`](/api/get-streams),
 | 
						||
  [`POST /register`](/api/register-queue),
 | 
						||
  [`GET /events`](/api/get-events): Renamed
 | 
						||
  stream setting `can_remove_subscribers_group_id`
 | 
						||
  to `can_remove_subscribers_group`.
 | 
						||
 | 
						||
**Feature level 196**
 | 
						||
 | 
						||
* [`POST /realm/playgrounds`](/api/add-code-playground): `url_prefix` is
 | 
						||
  replaced by `url_template`, which only accepts [RFC 6570][rfc6570] compliant
 | 
						||
  URL templates. The old prefix format is no longer supported.
 | 
						||
* [`GET /events`](/api/get-events), [`POST /register`](/api/register-queue):
 | 
						||
  `url_prefix` is replaced by `url_template` in `realm_playgrounds` events.
 | 
						||
 | 
						||
**Feature level 195**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events), [`POST /register`](/api/register-queue):
 | 
						||
  The `default_code_block_language` realm setting is now consistently an
 | 
						||
  empty string when no default pygments language code is set. Previously,
 | 
						||
  the server had a bug that meant it might represent no default for this
 | 
						||
  realm setting as either `null` or an empty string. Clients supporting
 | 
						||
  older server versions should treat either value (`null` or `""`) as no
 | 
						||
  default being set.
 | 
						||
 | 
						||
**Feature level 194**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-messages),
 | 
						||
  [`GET /messages/matches_narrow`](/api/check-messages-match-narrow),
 | 
						||
  [`POST /messages/flags/narrow`](/api/update-message-flags-for-narrow),
 | 
						||
  [`POST /register`](/api/register-queue):
 | 
						||
  For [search/narrow filters](/api/construct-narrow#message-ids) with the
 | 
						||
  `id` operator, added support for encoding the message ID operand as either
 | 
						||
  a string or an integer. Previously, only string encoding was supported.
 | 
						||
 | 
						||
**Feature level 193**
 | 
						||
 | 
						||
* [`POST /messages/{message_id}/reactions`](/api/add-reaction),
 | 
						||
  [`DELETE /messages/{message_id}/reactions`](/api/remove-reaction):
 | 
						||
  Endpoints return specific error responses if an emoji reaction
 | 
						||
  already exists when adding a reaction (`"code": "REACTION_ALREADY_EXISTS"`)
 | 
						||
  or if an emoji reaction does not exist when deleting a reaction
 | 
						||
  (`"code": "REACTION_DOES_NOT_EXIST"`). Previously, these errors
 | 
						||
  returned the `"BAD_REQUEST"` code.
 | 
						||
 | 
						||
**Feature level 192**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Stream creation events are now
 | 
						||
  sent when guest users gain access to a public stream by being
 | 
						||
  subscribed. Guest users previously only received these events when
 | 
						||
  subscribed to private streams.
 | 
						||
 | 
						||
**Feature level 191**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events), [`POST /register`](/api/register-queue),
 | 
						||
  [`GET /user_groups`](/api/get-user-groups): Add `can_mention_group_id` to
 | 
						||
  user group objects.
 | 
						||
* [`POST /user_groups/create`](/api/create-user-group): Added `can_mention_group_id`
 | 
						||
  parameter to support setting the user group whose members can mention the new user
 | 
						||
  group.
 | 
						||
* [`PATCH /user_groups/{user_group_id}`](/api/update-user-group): Added
 | 
						||
  `can_mention_group_id` parameter to support changing the user group whose
 | 
						||
  members can mention the specified user group.
 | 
						||
 | 
						||
**Feature level 190**
 | 
						||
 | 
						||
* [`DELETE /realm/emoji/{emoji_name}`](/api/deactivate-custom-emoji): This endpoint
 | 
						||
  now returns an HTTP status code of 404 when an emoji does not exist, instead of 400.
 | 
						||
 | 
						||
**Feature level 189**
 | 
						||
 | 
						||
* [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults),
 | 
						||
  [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings):
 | 
						||
  Added new boolean user settings  `enable_followed_topic_email_notifications`,
 | 
						||
  `enable_followed_topic_push_notifications`,
 | 
						||
  `enable_followed_topic_wildcard_mentions_notify`,
 | 
						||
  `enable_followed_topic_desktop_notifications`
 | 
						||
  and `enable_followed_topic_audible_notifications` to control whether a user
 | 
						||
  receives email, push, wildcard mention, visual desktop and audible desktop
 | 
						||
  notifications, respectively, for messages sent to followed topics.
 | 
						||
 | 
						||
**Feature level 188**
 | 
						||
 | 
						||
* [`POST /users/me/muted_users/{muted_user_id}`](/api/mute-user),
 | 
						||
  [`DELETE /users/me/muted_users/{muted_user_id}`](/api/unmute-user):
 | 
						||
  Added support to mute/unmute bot users.
 | 
						||
 | 
						||
Feature levels 186-187 are reserved for future use in 7.x maintenance
 | 
						||
releases.
 | 
						||
 | 
						||
## Changes in Zulip 7.0
 | 
						||
 | 
						||
**Feature level 185**
 | 
						||
 | 
						||
No changes; feature level used for Zulip 7.0 release.
 | 
						||
 | 
						||
**Feature level 184**
 | 
						||
 | 
						||
* [`PATCH /scheduled_messages/<int:scheduled_message_id>`](/api/update-scheduled-message):
 | 
						||
  Added new endpoint for editing an existing scheduled message.
 | 
						||
* [`POST /scheduled_messages`](/api/create-scheduled-message):
 | 
						||
  Removed optional `scheduled_message_id` parameter, which had
 | 
						||
  been a previous way for clients to support editing an existing
 | 
						||
  scheduled message.
 | 
						||
 | 
						||
**Feature level 183**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Removed the
 | 
						||
  `realm_community_topic_editing_limit_seconds` property, which was no
 | 
						||
  longer in use. The time limit for editing topics is controlled by the
 | 
						||
  realm setting `move_messages_within_stream_limit_seconds`, see feature
 | 
						||
  level 162.
 | 
						||
* [`GET /events`](/api/get-events): Removed the `community_topic_editing_limit_seconds`
 | 
						||
  property from realm `update_dict` event documentation, because it was
 | 
						||
  never returned as a changed property in this event and was only ever
 | 
						||
  returned in the [`POST /register`](/api/register-queue) response.
 | 
						||
 | 
						||
**Feature level 182**
 | 
						||
 | 
						||
* [`POST /export/realm`](/api/export-realm): This endpoint now returns the ID
 | 
						||
  of the data export object created by the request.
 | 
						||
 | 
						||
**Feature level 181**
 | 
						||
 | 
						||
* [`GET /scheduled_messages`](/api/get-scheduled-messages), [`GET
 | 
						||
  /events`](/api/get-events), [`POST /register`](/api/register-queue):
 | 
						||
  Added `failed` boolean field to scheduled message objects to
 | 
						||
  indicate if the server tried to send the scheduled message and was
 | 
						||
  unsuccessful. Clients that support unscheduling and editing
 | 
						||
  scheduled messages should use this field to indicate to the user
 | 
						||
  when a scheduled message failed to send at the appointed time.
 | 
						||
 | 
						||
**Feature level 180**
 | 
						||
 | 
						||
* [`POST /invites`](/api/send-invites): Added support for invitations specifying
 | 
						||
  the empty list as the user's initial stream subscriptions. Previously, this
 | 
						||
  returned an error. This change was also backported to Zulip 6.2, and
 | 
						||
  is available at feature levels 157-158 as well.
 | 
						||
 | 
						||
**Feature level 179**
 | 
						||
 | 
						||
* [`POST /scheduled_messages`](/api/create-scheduled-message):
 | 
						||
  Added new endpoint to create and edit scheduled messages.
 | 
						||
* [`GET /events`](/api/get-events):
 | 
						||
  Added `scheduled_messages` events sent to clients when a user creates,
 | 
						||
  edits or deletes scheduled messages.
 | 
						||
* [`POST /register`](/api/register-queue):
 | 
						||
  Added an optional `scheduled_messages` field to that includes all
 | 
						||
  of the undelivered scheduled messages for the current user.
 | 
						||
 | 
						||
**Feature level 178**
 | 
						||
 | 
						||
* [`POST /users/me/presence`](/api/update-presence),
 | 
						||
  [`GET /users/<user_id_or_email>/presence`](/api/get-user-presence),
 | 
						||
  [`GET /realm/presence`](/api/get-presence),
 | 
						||
  [`POST /register`](/api/register-queue),
 | 
						||
  [`GET /events`](/api/get-events):
 | 
						||
  The server no longer stores which client submitted presence data,
 | 
						||
  and presence responses from the server will always contain the
 | 
						||
  `"aggregated"` and `"website"` keys.
 | 
						||
 | 
						||
**Feature level 177**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-messages),
 | 
						||
  [`GET /messages/matches_narrow`](/api/check-messages-match-narrow),
 | 
						||
  [`POST /messages/flags/narrow`](/api/update-message-flags-for-narrow),
 | 
						||
  [`POST /register`](/api/register-queue):
 | 
						||
  Added support for three [search/narrow filters](/api/construct-narrow#changes)
 | 
						||
  related to direct messages: `is:dm`, `dm` and `dm-including`.
 | 
						||
  The `dm` operator replaces and deprecates the `pm-with` operator.
 | 
						||
  The `is:dm` filter replaces and deprecates the `is:private` filter.
 | 
						||
  The `dm-including` operator replaces and deprecates the `group-pm-with`
 | 
						||
  operator. Because existing Zulip messages may have links with these
 | 
						||
  legacy filters, they are still supported for backwards-compatibility.
 | 
						||
 | 
						||
**Feature level 176**
 | 
						||
 | 
						||
* [`POST /realm/filters`](/api/add-linkifier),
 | 
						||
  [`PATCH /realm/filters/<int:filter_id>`](/api/update-linkifier):
 | 
						||
  The `url_format_string` parameter is replaced by `url_template`.
 | 
						||
  [Linkifiers](/help/add-a-custom-linkifier) now only accept
 | 
						||
  [RFC 6570][rfc6570] compliant URL templates. The old URL format
 | 
						||
  strings are no longer supported.
 | 
						||
* [`GET /events`](/api/get-events), [`POST /register`](/api/register-queue):
 | 
						||
  The `url_format_string` key in `realm_linkifiers` objects is replaced
 | 
						||
  by `url_template`. For backwards-compatibility, clients that do not
 | 
						||
  support the `linkifier_url_template`
 | 
						||
  [client capability](/api/register-queue#parameter-client_capabilities)
 | 
						||
  will receive an empty `realm_linkifiers` array in the `/register`
 | 
						||
  response and not receive `realm_linkifiers` events. Unconditionally,
 | 
						||
  the deprecated `realm_filters` event type returns an empty array in
 | 
						||
  the `/register` response and these events are no longer sent to
 | 
						||
  clients.
 | 
						||
 | 
						||
**Feature level 175**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings),
 | 
						||
  [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults):
 | 
						||
  Added new user setting `web_mark_read_on_scroll_policy`. Clients may use this to
 | 
						||
  determine the user's preference on whether to mark messages as read or not when
 | 
						||
  scrolling through their message feed.
 | 
						||
 | 
						||
**Feature level 174**
 | 
						||
 | 
						||
* [`POST /typing`](/api/set-typing-status), [`POST /messages`](/api/send-message):
 | 
						||
  Added `"direct"` as the preferred way to indicate a direct message for the
 | 
						||
  `type` parameter, deprecating the original `"private"`. While `"private"`
 | 
						||
  is still supported for direct messages, clients are encouraged to use
 | 
						||
  the modern convention with servers that support it, because support for
 | 
						||
  `"private"` may eventually be removed.
 | 
						||
 | 
						||
**Feature level 173**
 | 
						||
 | 
						||
* [`GET /scheduled_messages`](/api/get-scheduled-messages), [`DELETE
 | 
						||
  /scheduled_messages/<int:scheduled_message_id>`](/api/delete-scheduled-message):
 | 
						||
  Added new endpoints to fetch and delete scheduled messages.
 | 
						||
 | 
						||
**Feature level 172**
 | 
						||
 | 
						||
* [`PATCH /messages/{message_id}`](/api/update-message):
 | 
						||
  [Topic editing restrictions](/help/restrict-moving-messages) now apply
 | 
						||
  to stream messages without a topic.
 | 
						||
* [`PATCH /messages/{message_id}`](/api/update-message): When users, other
 | 
						||
  than organization administrators and moderators, use
 | 
						||
  `"propagate_mode": "change_all"` to move messages that have passed the
 | 
						||
  organization's time limit for updating a message's topic and/or stream,
 | 
						||
  this endpoint now returns an error response
 | 
						||
  (`"code": "MOVE_MESSAGES_TIME_LIMIT_EXCEEDED"`).
 | 
						||
 | 
						||
**Feature level 171**
 | 
						||
 | 
						||
* [`POST /fetch_api_key`](/api/fetch-api-key),
 | 
						||
  [`POST /dev_fetch_api_key`](/api/dev-fetch-api-key): The return values
 | 
						||
  for these endpoints now include the unique ID of the user who owns the
 | 
						||
  API key.
 | 
						||
 | 
						||
**Feature level 170**
 | 
						||
 | 
						||
* [`POST /user_topics`](/api/update-user-topic): Added a new endpoint to
 | 
						||
  update a user's personal preferences for a topic, which deprecates the
 | 
						||
  [`PATCH /users/me/subscriptions/muted_topics`](/api/mute-topic) endpoint.
 | 
						||
  The deprecated endpoint is maintained for backwards-compatibility but may be
 | 
						||
  removed in a future release.
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events):
 | 
						||
  Unmuted added as a visibility policy option to the objects sent in response
 | 
						||
  to the `user_topic` event.
 | 
						||
 | 
						||
**Feature level 169**
 | 
						||
 | 
						||
* [`PATCH /users/me/subscriptions/muted_topics`](/api/mute-topic):
 | 
						||
  Trying to mute a topic that is already muted or unmute a topic
 | 
						||
  that was not previously muted now results in a success response
 | 
						||
  rather than an error.
 | 
						||
 | 
						||
**Feature level 168**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings),
 | 
						||
  [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults):
 | 
						||
  Replaced the boolean user setting `realm_name_in_notifications`
 | 
						||
  with an integer `realm_name_in_email_notifications_policy`.
 | 
						||
 | 
						||
**Feature level 167**
 | 
						||
 | 
						||
* [All REST API endpoints](/api/rest-error-handling#ignored-parameters):
 | 
						||
  Implemented `ignored_parameters_unsupported` as a possible return value
 | 
						||
  in the JSON success response for all endpoints. This value is a array
 | 
						||
  of any parameters that were sent in the request by the client that are
 | 
						||
  not supported by the endpoint. Previously, unsupported parameters were
 | 
						||
  silently ignored, except in the subset of endpoints which already
 | 
						||
  supported this return value; see feature levels 111, 96 and 78.
 | 
						||
 | 
						||
**Feature level 166**
 | 
						||
 | 
						||
* [`POST /messages`](/api/send-message): Eliminated the undocumented
 | 
						||
  `realm_str` parameter. This parameter was already redundant due to
 | 
						||
  it needing to match the realm of the user making the request, otherwise
 | 
						||
  returning an authorization error. With this, the parameter is removed,
 | 
						||
  meaning that if provided in the API request, it will be ignored.
 | 
						||
 | 
						||
**Feature level 165**
 | 
						||
 | 
						||
* [`PATCH /user_groups/{user_group_id}`](/api/update-user-group): The
 | 
						||
  `name` and `description` parameters are now optional.
 | 
						||
 | 
						||
**Feature level 164**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added the
 | 
						||
  `server_presence_ping_interval_seconds` and
 | 
						||
  `server_presence_offline_threshold_seconds` fields for clients
 | 
						||
  to use when implementing the [presence](/api/get-presence) system.
 | 
						||
 | 
						||
**Feature level 163**
 | 
						||
 | 
						||
* [`GET /users`](/api/get-users), [`GET /users/{user_id}`](/api/get-user),
 | 
						||
  [`GET /users/{email}`](/api/get-user-by-email),
 | 
						||
  [`GET /users/me`](/api/get-own-user), [`GET /events`](/api/get-events):
 | 
						||
  The `delivery_email` field is always present in user objects, including
 | 
						||
  the case when a user's `email_address_visibility` is set to everyone.
 | 
						||
  The value will be `null` if the requester does not have access to the
 | 
						||
  user's real email. For bot users, the `delivery_email` field is always
 | 
						||
  set to the bot user's real email.
 | 
						||
* [`GET /events`](/api/get-events): Event for updating a user's
 | 
						||
  `delivery_email` is now sent to all users who have access to it, and
 | 
						||
  is also sent when a user's `email_address_visibility` setting changes.
 | 
						||
* [`GET /events`](/api/get-events), [`POST /register`](/api/register-queue)
 | 
						||
  [`GET /users`](/api/get-users), [`GET /users/{user_id}`](/api/get-user),
 | 
						||
  [`GET /users/{email}`](/api/get-user-by-email),
 | 
						||
  [`GET /users/me`](/api/get-own-user), [`GET /messages`](/api/get-messages),
 | 
						||
  [`GET /messages/{message_id}`](/api/get-message): Whether the `avatar_url`
 | 
						||
  field in message and user objects returned by these endpoints can be `null`
 | 
						||
  now depends on if the current user has access to the other user's real
 | 
						||
  email address based on the other user's `email_address_visibility` policy.
 | 
						||
* [`POST /register`](/api/register-queue), [`PATCH /settings`](/api/update-settings),
 | 
						||
  [`PATCH /realm/user_settings_defaults`](/api/update-realm-user-settings-defaults):
 | 
						||
  Added user setting `email_address_visibility`, to replace the
 | 
						||
  realm setting `email_address_visibility`.
 | 
						||
* [`POST /register`](/api/register-queue), `PATCH /realm`: Removed realm
 | 
						||
  setting `email_address_visibility`.
 | 
						||
 | 
						||
**Feature level 162**
 | 
						||
 | 
						||
* `PATCH /realm`, [`POST /register`](/api/register-queue),
 | 
						||
   [`GET /events`](/api/get-events): Added two new realm settings
 | 
						||
  `move_messages_within_stream_limit_seconds` and
 | 
						||
  `move_messages_between_streams_limit_seconds` for organizations to
 | 
						||
  configure time limits for editing topics and moving messages between streams.
 | 
						||
* [`PATCH /messages/{message_id}`](/api/update-message): For users other than
 | 
						||
  administrators and moderators, the time limit for editing topics is now
 | 
						||
  controlled via the realm setting `move_messages_within_stream_limit_seconds`
 | 
						||
  and the time limit for moving messages between streams is now controlled by
 | 
						||
  the realm setting `move_messages_between_streams_limit_seconds`.
 | 
						||
 | 
						||
**Feature level 161**
 | 
						||
 | 
						||
* [`POST /users/me/subscriptions`](/api/subscribe),
 | 
						||
  [`PATCH /streams/{stream_id}`](/api/update-stream): Added
 | 
						||
  `can_remove_subscribers_group_id` parameter to support setting and
 | 
						||
  changing the user group whose members can remove other subscribers
 | 
						||
  from the specified stream.
 | 
						||
* [`DELETE /users/me/subscriptions`](/api/unsubscribe): Expanded the
 | 
						||
  situations where users can use this endpoint to unsubscribe other
 | 
						||
  users from a stream to include the case where the current user has
 | 
						||
  access to the stream and is a member of the user group specified by
 | 
						||
  the `can_remove_subscribers_group_id` for the stream.
 | 
						||
 | 
						||
**Feature level 160**
 | 
						||
 | 
						||
* `POST /api/v1/jwt/fetch_api_key`: Added new endpoint to fetch API
 | 
						||
  keys using JSON Web Token (JWT) authentication.
 | 
						||
* `accounts/login/jwt/`: Adjusted format of requests to undocumented,
 | 
						||
  optional endpoint for JWT authentication log in support.
 | 
						||
 | 
						||
**Feature level 159**
 | 
						||
 | 
						||
* `PATCH /realm`, [`POST /register`](/api/register-queue),
 | 
						||
  [`GET /events`](/api/get-events):
 | 
						||
  Nobody added as an option for the realm settings `edit_topic_policy`
 | 
						||
  and `move_messages_between_streams_policy`.
 | 
						||
* [`PATCH /messages/{message_id}`](/api/update-message): Permission
 | 
						||
  to edit the stream and/or topic of messages no longer depends on the
 | 
						||
  realm setting `allow_message_editing`.
 | 
						||
* [`PATCH /messages/{message_id}`](/api/update-message): The user who
 | 
						||
  sent the message can no longer edit the message's topic indefinitely.
 | 
						||
 | 
						||
Feature level 158 is reserved for future use in 6.x maintenance
 | 
						||
releases.
 | 
						||
 | 
						||
## Changes in Zulip 6.2
 | 
						||
 | 
						||
**Feature level 157**
 | 
						||
 | 
						||
* [`POST /invites`](/api/send-invites): Added support for invitations specifying
 | 
						||
  the empty list as the user's initial stream subscriptions. Previously, this
 | 
						||
  returned an error. This change was backported from the Zulip 7.0
 | 
						||
  branch, and thus is available at feature levels 157-158 and 180+.
 | 
						||
 | 
						||
## Changes in Zulip 6.0
 | 
						||
 | 
						||
**Feature level 156**
 | 
						||
 | 
						||
No changes; feature level used for Zulip 6.0 release.
 | 
						||
 | 
						||
**Feature level 155**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-messages): The new `include_anchor`
 | 
						||
  parameter controls whether a message with ID matching the specified
 | 
						||
  `anchor` should be included.
 | 
						||
* The `update_message_flags` event sent by [`POST
 | 
						||
  /messages/flags`](/api/update-message-flags) no longer redundantly
 | 
						||
  lists messages where the flag was set to the same state it was
 | 
						||
  already in.
 | 
						||
* [`POST /messages/flags/narrow`](/api/update-message-flags-for-narrow):
 | 
						||
  This new endpoint allows updating message flags on a range of
 | 
						||
  messages within a narrow.
 | 
						||
 | 
						||
**Feature level 154**
 | 
						||
 | 
						||
* [`POST /streams/{stream_id}/delete_topic`](/api/delete-topic):
 | 
						||
  When the process of deleting messages times out, but successfully
 | 
						||
  deletes some messages in the topic (see feature level 147 for when
 | 
						||
  this endpoint started deleting messages in batches), a success
 | 
						||
  response with `"result": "partially_completed"` will now be returned
 | 
						||
  by the server, analogically to the `POST /mark_all_as_read` endpoint
 | 
						||
  (see feature level 153 entry below).
 | 
						||
 | 
						||
**Feature level 153**
 | 
						||
 | 
						||
* [`POST /mark_all_as_read`](/api/mark-all-as-read): Messages are now
 | 
						||
  marked as read in batches, so that progress will be made even if the
 | 
						||
  request times out because of an extremely large number of unread
 | 
						||
  messages to process. Upon timeout, a success response with
 | 
						||
  `"result": "partially_completed"` will be returned by the server.
 | 
						||
 | 
						||
**Feature level 152**
 | 
						||
 | 
						||
* [`PATCH /messages/{message_id}`](/api/update-message):
 | 
						||
  The default value for `send_notification_to_old_thread` was changed from
 | 
						||
  `true` to `false`.
 | 
						||
  When moving a topic within a stream, the `send_notification_to_old_thread`
 | 
						||
  and `send_notification_to_new_thread` parameters are now respected, and by
 | 
						||
  default a notification is sent to the new thread.
 | 
						||
 | 
						||
**Feature level 151**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events),
 | 
						||
  [`POST /realm/profile_fields`](/api/create-custom-profile-field),
 | 
						||
  [`GET /realm/profile_fields`](/api/get-custom-profile-fields): Added
 | 
						||
  pronouns custom profile field type.
 | 
						||
 | 
						||
**Feature level 150**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Separate events are now sent on changing
 | 
						||
  `allow_message_editing`, `message_content_edit_limit_seconds` and
 | 
						||
  `edit_topic_policy` settings, whereas previously one event was sent including
 | 
						||
  all of these setting values irrespective of which of them were actually changed.
 | 
						||
* `PATCH /realm`: Only changed settings are included in the response data now
 | 
						||
  when changing `allow_message_editing`, `edit_topic_policy` and
 | 
						||
  `message_content_edit_limit_seconds` settings, instead of including all the
 | 
						||
  fields even if one of these settings was changed.
 | 
						||
 | 
						||
**Feature level 149**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): The `client_gravatar` and
 | 
						||
  `include_subscribers` parameters now return an error for
 | 
						||
  [unauthenticated requests](/help/public-access-option) if an
 | 
						||
  unsupported value is requested by the client.
 | 
						||
 | 
						||
**Feature level 148**
 | 
						||
 | 
						||
* [`POST /users/me/status`](/api/update-status),
 | 
						||
  [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events):
 | 
						||
  The user status `away` field/parameter is deprecated, and as of this
 | 
						||
  feature level are a legacy way to access the user's `presence_enabled`
 | 
						||
  setting, with `away = !presence_enabled`. To be removed in a future
 | 
						||
  release.
 | 
						||
 | 
						||
**Feature level 147**
 | 
						||
 | 
						||
* [`POST /streams/{stream_id}/delete_topic`](/api/delete-topic):
 | 
						||
  Messages now are deleted in batches, starting from the newest, so
 | 
						||
  that progress will be made even if the request times out because of
 | 
						||
  an extremely large topic.
 | 
						||
 | 
						||
**Feature level 146**
 | 
						||
 | 
						||
* [`POST /realm/profile_fields`](/api/create-custom-profile-field),
 | 
						||
[`GET /realm/profile_fields`](/api/get-custom-profile-fields): Added a
 | 
						||
new parameter `display_in_profile_summary`, which clients use to
 | 
						||
decide whether to display the field in a small/summary section of the
 | 
						||
user's profile.
 | 
						||
 | 
						||
**Feature level 145**
 | 
						||
 | 
						||

						||
 | 
						||
* [`GET /messages/{message_id}/read_receipts`](/api/get-read-receipts):

						||

 | 
						||
  of users who have been muted by or have muted the current user.
 | 
						||
 | 
						||
**Feature level 143**
 | 
						||
 | 
						||
* `PATCH /realm`: The `disallow_disposable_email_addresses`,
 | 
						||
  `emails_restricted_to_domains`, `invite_required`, and
 | 
						||
  `waiting_period_threshold` settings can no longer be changed by
 | 
						||
  organization administrators who are not owners.
 | 
						||
* `PATCH /realm/domains`, `POST /realm/domains`, `DELETE

 | 
						||
 | 
						||
**Feature level 139**
 | 
						||
 | 
						||
* [`GET /get-events`](/api/get-events): When a user mutes or unmutes
 | 
						||
  their subscription to a stream, a `subscription` update event
 | 
						||
  is now sent for the `is_muted` property and for the deprecated
 | 
						||
  `in_home_view` property to support clients fully migrating to use the
 | 
						||
  `is_muted` property. Prior to this feature level, only one event was
 | 
						||
  sent to clients with the deprecated `in_home_view` property.
 | 
						||
 | 
						||
**Feature level 138**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue), [`GET
 | 
						||
  /events`](/api/get-events): `message_content_edit_limit_seconds`
 | 
						||
  now represents no limit using `null`, instead of the integer 0.
 | 
						||
* `PATCH /realm`: One now sets `message_content_edit_limit_seconds`
 | 
						||
  to no limit by passing the string `unlimited`, rather than the
 | 
						||
  integer 0.
 | 
						||
 | 
						||
**Feature level 137**
 | 
						||
 | 
						||
* [`GET /messages/{message_id}/read_receipts`](/api/get-read-receipts):

 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Added `user_topic` event type
 | 
						||
  which is sent when a topic is muted or unmuted. This generalizes and
 | 
						||
  replaces the previous `muted_topics` array, which will no longer be
 | 
						||
  sent if `user_topic` was included in `event_types` when registering
 | 
						||
  the queue.
 | 
						||
* [`POST /register`](/api/register-queue): Added `user_topics` array
 | 
						||
  to the response. This generalizes and replaces the previous
 | 
						||
  `muted_topics` array, which will no longer be sent if `user_topic`
 | 
						||
  is included in `fetch_event_types`.
 | 
						||
* [`GET /events`](/api/get-events): When private streams are made
 | 
						||
  public, `stream` events for `op: "create"` and `subscription` events
 | 
						||
  for `op: "peer_add"` are now sent to clients.
 | 
						||
 | 
						||
**Feature level 133**

 |

 | 
						||
 | 
						||
## Changes in Zulip 5.0
 | 
						||
 | 
						||
**Feature level 122**
 | 
						||
 | 
						||
No changes; feature level used for Zulip 5.0 release.
 | 
						||
 | 
						||
**Feature level 121**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Added `message_details` field
 | 
						||
  appearing in message flag update events when marking previously read
 | 
						||
  messages as unread.
 | 
						||
 | 
						||
**Feature level 120**
 | 
						||
 | 
						||
* [`GET /messages/{message_id}`](/api/get-message): This endpoint
 | 
						||
  now sends the full message details. Previously, it only returned
 | 
						||
  the message's raw Markdown content.
 | 
						||
 | 
						||
**Feature level 119**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added `other_user_id` field
 | 
						||
  to the `pms` objects in the `unread_msgs` data set, deprecating the
 | 
						||
  less clearly named `sender_id` field. This change was motivated by
 | 
						||
  the possibility that a one-on-one direct message sent by the current
 | 
						||
  user to another user could be marked as unread. The `sender_id` field
 | 
						||
  is still present for backwards compatibility with older server versions.
 | 
						||
 | 
						||
**Feature level 118**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-messages), [`GET
 | 
						||
  /events`](/api/get-events): Improved the format of the
 | 
						||
  `edit_history` object within message objects. Entries for stream
 | 
						||
  edits now include a both a `prev_stream` and `stream` field to
 | 
						||
  indicate the previous and current stream IDs. Prior to this feature
 | 
						||
  level, only the `prev_stream` field was present. Entries for topic
 | 
						||
  edits now include both a `prev_topic` and `topic` field to indicate
 | 
						||
  the previous and current topic, replacing the `prev_subject`
 | 
						||
  field. These changes substantially simplify client complexity for
 | 
						||
  processing historical message edits.
 | 
						||
 | 
						||
* [`GET /messages/{message_id}/history`](/api/get-message-history):
 | 
						||
  Added `stream` field to message history `snapshot` indicating
 | 
						||
  the updated stream ID of messages moved to a new stream.
 | 
						||
 | 
						||
**Feature level 117**
 | 
						||
 | 
						||
* [`POST /invites`](/api/send-invites),
 | 
						||
  [`POST /invites/multiuse`](/api/create-invite-link): Added support
 | 
						||
  for passing `null` as the `invite_expires_in_days` parameter to
 | 
						||
  request an invitation that never expires.
 | 
						||
 | 
						||
**Feature level 116**
 | 
						||
 | 
						||
* [`GET /server_settings`](/api/get-server-settings): Added
 | 
						||
  `realm_web_public_access_enabled` as a realm-specific server setting,
 | 
						||
  which can be used by clients to detect whether the realm allows and
 | 
						||
  has at least one [web-public stream](/help/public-access-option).
 | 
						||
 | 
						||
**Feature level 115**
 | 
						||
 | 
						||
* Mobile push notifications about stream messages now include the
 | 
						||
  `stream_id` field.
 | 
						||
 | 
						||
**Feature level 114**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Added `rendering_only` field to
 | 
						||
  `update_message` event type to indicate if the message change only
 | 
						||
  updated the rendering of the message or if it was the result of a
 | 
						||
  user interaction.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Updated `update_message` event type
 | 
						||
  to always include `edit_timestamp` and `user_id` fields. If the event
 | 
						||
  only updates the rendering of the message, then the `user_id` field
 | 
						||
  will be present, but with a value of null as the update was not the
 | 
						||
  result of a user interaction.
 | 
						||
 | 
						||
**Feature level 113**
 | 
						||
 | 
						||
* `GET /realm/emoji`, `POST /realm/emoji/{emoji_name}`, [`GET
 | 
						||
  /events`](/api/get-events), [`POST /register`](/api/register-queue):
 | 
						||
  The `still_url` field for custom emoji objects is now always
 | 
						||
  present, with a value of null for non-animated emoji. Previously, it
 | 
						||
  only was present for animated emoji.
 | 
						||
 | 
						||
**Feature level 112**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Updated `update_message` event type
 | 
						||
  to include `stream_id` field for all edits to stream messages.
 | 
						||
 | 
						||
**Feature level 111**
 | 
						||
 | 
						||
* [`POST /users/me/subscriptions/properties`](/api/update-subscription-settings):
 | 
						||
  Removed `subscription_data` from response object, replacing it with
 | 
						||
  `ignored_parameters_unsupported`.

						||
 | 
						||
* [`POST /register`](/api/register-queue): Added

						||
 | 
						||
**Feature level 107**
 | 
						||

						||

						||
  Added user setting `escape_navigates_to_default_view` to allow users to
 | 
						||
  [disable the keyboard shortcut](/help/configure-home-view) for the `Esc` key that
 | 
						||
  navigates the app to the default view.
 | 
						||
 | 
						||
**Feature level 106**
 | 
						||
 | 
						||
* [`PATCH /user/{user_id}`](/api/update-user): Removed unnecessary JSON-encoding of string
 | 
						||
  parameter `full_name`.
 | 
						||
 | 
						||

						||
**Feature level 104**

						||
 | 
						||

 | 
						||
* [`POST /register`](/api/register-queue): The `create_stream_policy`
 | 
						||
  property was deprecated in favor of the

  `PATCH /realm`: The `default_twenty_four_hour_time` parameter to
 | 
						||
  `PATCH /realm` has been replaced by the `twenty_four_hour_time` parameter

  user preference defaults settings.
 | 
						||

* `PATCH /realm`, [`PATCH /streams/{stream_id}`](/api/update-stream):
 | 
						||

  messages are not automatically deleted.
 | 
						||
 | 
						||
**Feature level 90**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): The `unread_msgs` section
 | 
						||
  of the response no longer includes `sender_ids` in the `streams`
 | 
						||
  dictionaries. These were removed because no clients were interested

						||
**Feature level 89**

						||
* [`POST /register`](/api/register-queue): Added the
 | 
						||
  `user_settings_object` property to supported `client_capabilities`.

						||
  personal settings in the top-level response.

  `client_capabilities` when the event queue was created.

						||
 | 
						||
**Feature level 88**

						||
 | 
						||
**Feature level 80**
 | 
						||
 | 
						||
* [`PATCH /settings`](/api/update-settings): The
 | 
						||
  `/settings/notifications` and `/settings/display` endpoints were
 | 
						||
  merged into the main `/settings` endpoint; now all personal settings

 | 
						||
  preserved as deprecated aliases for backwards compatibility.
 | 
						||
 | 
						||
**Feature level 79**
 | 
						||
 | 
						||
* [`GET /users/me/subscriptions`](/api/get-subscriptions): The
 | 
						||
  `subscribers` field now returns user IDs if `include_subscribers` is

 | 
						||
  addresses in this field.

 | 
						||
  requests that involve a deactivated user or organization now use the

* `PATCH /realm`: Added `giphy_rating` parameter.
 | 
						||
 | 
						||
**Feature level 54**
 | 
						||
 | 
						||
* `GET /realm/filters` has been removed and replace with [`GET
 | 
						||
  /realm/linkifiers`](/api/get-linkifiers) which returns the data in a
 | 
						||
  cleaner dictionary format.
 | 
						||
* [`GET /events`](/api/get-events): Introduced new event type
 | 
						||
  `realm_linkifiers`.  The previous `realm_filters` event type is
 | 
						||
  still supported for backwards compatibility, but will be removed in
 | 
						||
  a future release.
 | 
						||
* [`POST /register`](/api/register-queue): The response now supports a
 | 
						||
  `realm_linkifiers` event type, containing the same data as the
 | 
						||
  legacy `realm_filters` key, with a more extensible object
 | 
						||
  format. The previous `realm_filters` event type is still supported
 | 
						||
  for backwards compatibility, but will be removed in a future
 | 
						||
  release. The legacy `realm_filters` key is deprecated but remains
 | 
						||
  available for backwards compatibility.
 | 
						||
 | 
						||
**Feature level 53**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added `max_topic_length`
 | 
						||
  and `max_message_length`, and renamed `max_stream_name_length` and
 | 
						||
  `max_stream_description_length` to allow clients to transparently
 | 
						||
  support these values changing in a future server version.
 | 
						||
 | 
						||
**Feature level 52**
 | 
						||
 | 
						||
* `PATCH /realm`: Removed unnecessary JSON-encoding of string
 | 
						||
  parameters `name`, `description`, `default_language`, and
 | 
						||
  `default_code_block_language`.
 | 
						||
 | 
						||
**Feature level 51**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added a new boolean field
 | 
						||
`can_invite_others_to_realm`.
 | 
						||
 | 
						||
**Feature level 50**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Replaced `invite_by_admins_only`
 | 
						||
field with an integer field `invite_to_realm_policy`.
 | 
						||
 | 
						||
**Feature level 49**
 | 
						||
 | 
						||
* Added new [`POST /realm/playground`](/api/add-code-playground) and
 | 
						||
  [`DELETE /realm/playground/{playground_id}`](/api/remove-code-playground)
 | 
						||
  endpoints for code playgrounds.
 | 
						||
* [`GET /events`](/api/get-events): A new `realm_playgrounds` events
 | 
						||
  is sent when changes are made to a set of configured code playgrounds for
 | 
						||
  an organization.
 | 
						||
* [`POST /register`](/api/register-queue): Added a new `realm_playgrounds`
 | 
						||
  field, which is required to fetch the set of configured code playgrounds for
 | 
						||
  an organization.
 | 
						||
 | 
						||
**Feature level 48**
 | 
						||
 | 
						||
* [`POST /users/me/muted_users/{muted_user_id}`](/api/mute-user),
 | 
						||
  [`DELETE /users/me/muted_users/{muted_user_id}`](/api/unmute-user):
 | 
						||
  New endpoints added to mute/unmute users.
 | 
						||
* [`GET /events`](/api/get-events): Added new event type `muted_users`
 | 
						||
  which will be sent to a user when the set of users muted by them has
 | 
						||
  changed.
 | 
						||
* [`POST /register`](/api/register-queue): Added a new `muted_users` field,
 | 
						||
  which identifies the set of other users the current user has muted.
 | 
						||
 | 
						||
**Feature level 47**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added a new `giphy_api_key`
 | 
						||
  field, which is required to fetch GIFs using the GIPHY API.
 | 
						||
 | 
						||
**Feature level 46**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-messages) and [`GET
 | 
						||
  /events`](/api/get-events): The `topic_links` field now contains a
 | 
						||
  list of dictionaries, rather than a list of strings.
 | 
						||
 | 
						||
**Feature level 45**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Removed useless `op` field from
 | 
						||
  `custom_profile_fields` events.  These events contain the full set
 | 
						||
  of configured `custom_profile_fields` for the organization
 | 
						||
  regardless of what triggered the change.
 | 
						||
 | 
						||
**Feature level 44**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): extended the `unread_msgs`
 | 
						||
  object to include `old_unreads_missing`, which indicates whether the
 | 
						||
  server truncated the `unread_msgs` due to excessive total unread
 | 
						||
  messages.
 | 
						||
 | 
						||
**Feature level 43**
 | 
						||
 | 
						||
* [`GET /users/{user_id_or_email}/presence`](/api/get-user-presence):
 | 
						||
  Added support for passing the `user_id` to identify the target user.
 | 
						||
 | 
						||
**Feature level 42**
 | 
						||
 | 
						||
* `PATCH /settings/display`: Added a new `default_view` setting allowing
 | 
						||
  the user to [set the default view](/help/configure-home-view).
 | 
						||
 | 
						||
**Feature level 41**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Removed `name` field from update
 | 
						||
  subscription events.
 | 
						||
 | 
						||
**Feature level 40**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Removed `email` field from update
 | 
						||
  subscription events.
 | 
						||
 | 
						||
**Feature level 39**
 | 
						||
 | 
						||
* Added new [`GET /users/{email}`](/api/get-user-by-email) endpoint.
 | 
						||
 | 
						||
**Feature level 38**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Increased
 | 
						||
  `realm_community_topic_editing_limit_seconds` time limit value
 | 
						||
  to 259200s (3 days).
 | 
						||
 | 
						||
**Feature level 37**
 | 
						||
 | 
						||
* Consistently provide `subscribers` in stream data when
 | 
						||
  clients register for subscriptions with `include_subscribers`,
 | 
						||
  even if the user can't access subscribers.
 | 
						||
 | 
						||
**Feature level 36**
 | 
						||
 | 
						||
* [`POST /users`](/api/create-user): Restricted access to organization
 | 
						||
  administrators with the `can_create_users` permission.
 | 
						||
* [Error handling](/api/rest-error-handling#common-error-responses): The
 | 
						||
  `code` key will now be present in errors that are due to rate
 | 
						||
  limits, with a value of `"RATE_LIMIT_HIT"`.
 | 
						||
 | 
						||
**Feature level 35**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): The `subscription` events for
 | 
						||
  `peer_add` and `peer_remove` now include `user_ids` and `stream_ids`
 | 
						||
  arrays. Previously, these events included singular `user_id` and
 | 
						||
  `stream_id` integers.
 | 
						||
 | 
						||
**Feature level 34**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added a new `wildcard_mention_policy`
 | 
						||
  setting for controlling who can use wildcard mentions in large streams.
 | 
						||
 | 
						||
**Feature level 33**
 | 
						||
 | 
						||
* [Markdown message formatting](/api/message-formatting#code-blocks):
 | 
						||
  [Code blocks](/help/code-blocks) now have a `data-code-language`
 | 
						||
  attribute attached to the outer HTML `div` element, recording the
 | 
						||
  programming language that was selected for syntax highlighting.
 | 
						||
 | 
						||
**Feature level 32**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Added `op` field to
 | 
						||
  `update_message_flags` events, deprecating the `operation` field
 | 
						||
  (which has the same value).  This removes an unintentional anomaly
 | 
						||
  in the format of this event type.
 | 
						||
 | 
						||
**Feature level 31**
 | 
						||
 | 
						||
* [`GET /users/me/subscriptions`](/api/get-subscriptions): Added a
 | 
						||
  `role` field to Subscription objects representing whether the user
 | 
						||
  is a stream administrator.
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): Added `role` field to
 | 
						||
  Subscription objects sent in `subscriptions` events.
 | 
						||
 | 
						||
Note that as of this feature level, stream administrators are a
 | 
						||
partially completed feature.  In particular, it is impossible for a
 | 
						||
user to be a stream administrator at this feature level.
 | 
						||
 | 
						||
**Feature level 30**
 | 
						||
 | 
						||
* [`GET /users/me/subscriptions`](/api/get-subscriptions), [`GET
 | 
						||
  /streams`](/api/get-streams): Added `date_created` to Stream
 | 
						||
  objects.
 | 
						||
* [`POST /users`](/api/create-user), `POST /bots`: The ID of the newly
 | 
						||
  created user is now returned in the response.
 | 
						||
 | 
						||
Feature levels 28 and 29 are reserved for future use in 3.x bug fix
 | 
						||
releases.
 | 
						||
 | 
						||
## Changes in Zulip 3.1
 | 
						||
 | 
						||
**Feature level 27**
 | 
						||
 | 
						||
* [`POST /users`](/api/create-user): Removed `short_name` field from
 | 
						||
  `display_recipient` array objects.
 | 
						||
 | 
						||
**Feature level 26**
 | 
						||
 | 
						||
* [`GET /messages`](/api/get-messages), [`GET /events`](/api/get-events):
 | 
						||
  The `sender_short_name` field is no longer included in message objects
 | 
						||
  returned by these endpoints.
 | 
						||
* [`GET /messages`](/api/get-messages) : Removed `short_name` field from
 | 
						||
  `display_recipient` array objects.
 | 
						||
 | 
						||
## Changes in Zulip 3.0
 | 
						||
 | 
						||
**Feature level 25**
 | 
						||
 | 
						||
No changes; feature level used for Zulip 3.0 release.
 | 
						||
 | 
						||
**Feature level 24**
 | 
						||
 | 
						||
* [Markdown message formatting](/api/message-formatting#removed-features):
 | 
						||
  The rarely used `!avatar()` and `!gravatar()` markup syntax, which
 | 
						||
  was never documented and had inconsistent syntax, was removed.
 | 
						||
 | 
						||
**Feature level 23**
 | 
						||
 | 
						||
* `GET/PUT/POST /users/me/pointer`: Removed.  Zulip 3.0 removes the
 | 
						||
  `pointer` concept from Zulip; this legacy data structure was
 | 
						||
  replaced by tracking unread messages and loading views centered on
 | 
						||
  the first unread message.
 | 
						||
 | 
						||
**Feature level 22**
 | 
						||
 | 
						||
* [`GET /attachments`](/api/get-attachments): The date when a message
 | 
						||
  using the attachment was sent is now correctly encoded as
 | 
						||
  `date_sent`, replacing the confusingly named `name` field.  The
 | 
						||
  `date_sent` and `create_time` fields of attachment objects are now
 | 
						||
  encoded as integers; (previously the implementation could send
 | 
						||
  floats incorrectly suggesting that microsecond precision is
 | 
						||
  relevant).
 | 
						||
* [`GET /invites`](/api/get-invites): Now encodes the user ID of the person
 | 
						||
   who created the invitation as `invited_by_user_id`, replacing the previous
 | 
						||
   `ref` field (which had that user's Zulip display email address).
 | 
						||
* [`POST /register`](/api/register-queue): The encoding of an
 | 
						||
  unlimited `realm_message_retention_days` in the response was changed
 | 
						||
  from `null` to `-1`.
 | 
						||
 | 
						||
**Feature level 21**
 | 
						||
 | 
						||
* `PATCH /settings/display`: Replaced the `night_mode` boolean with
 | 
						||
  `color_scheme` as part of supporting automatic night theme detection.
 | 
						||
 | 
						||
**Feature level 20**
 | 
						||
 | 
						||
* Added support for inviting users as organization owners to the
 | 
						||
  invitation endpoints.
 | 
						||
 | 
						||
**Feature level 19**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): The `subscription` events for
 | 
						||
  `peer_add` and `peer_remove` now identify the modified
 | 
						||
  stream by the `stream_id` field, replacing the old `name` field.
 | 
						||
 | 
						||
**Feature level 18**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added
 | 
						||
  `user_avatar_url_field_optional` to supported `client_capabilities`.
 | 
						||
 | 
						||
**Feature level 17**
 | 
						||
 | 
						||
* [`GET /users/me/subscriptions`](/api/get-subscriptions),
 | 
						||
  [`GET /streams`](/api/get-streams): Added
 | 
						||
  `message_retention_days` to Stream objects.
 | 
						||
* [`POST /users/me/subscriptions`](/api/subscribe), [`PATCH
 | 
						||
  /streams/{stream_id}`](/api/update-stream): Added `message_retention_days`
 | 
						||
  parameter.
 | 
						||
 | 
						||
**Feature level 16**
 | 
						||
 | 
						||
* [`GET /users/me`](/api/get-own-user): Removed `pointer` from the response,
 | 
						||
  as the "pointer" concept is being removed in Zulip.
 | 
						||
* Changed the rendered HTML markup for mentioning a time to use the
 | 
						||
  `<time>` HTML tag.  It is OK for clients to ignore the previous time
 | 
						||
  mention markup, as the feature was not advertised before this change.
 | 
						||
 | 
						||
**Feature level 15**
 | 
						||
 | 
						||
* [Markdown message formatting](/api/message-formatting#spoilers): Added
 | 
						||
  [spoilers](/help/spoilers) to supported message formatting features.
 | 
						||
 | 
						||
**Feature level 14**
 | 
						||
 | 
						||
* [`GET /users/me/subscriptions`](/api/get-subscriptions): Removed
 | 
						||
  the `is_old_stream` field from Stream objects.  This field was
 | 
						||
  always equivalent to `stream_weekly_traffic != null` on the same object.
 | 
						||
 | 
						||
**Feature level 13**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added
 | 
						||
  `bulk_message_deletion` to supported `client_capabilities`.
 | 
						||
* [`GET /events`](/api/get-events): `delete_message`
 | 
						||
  events have new behavior.  The `sender` and `sender_id` fields were
 | 
						||
  removed, and the `message_id` field was replaced by a `message_ids`
 | 
						||
  list for clients with the `bulk_message_deletion` client capability.
 | 
						||
  All clients should upgrade; we expect `bulk_message_deletion` to be
 | 
						||
  required in the future.
 | 
						||
 | 
						||
**Feature level 12**
 | 
						||
 | 
						||
* [`GET /users/{user_id}/subscriptions/{stream_id}`](/api/get-subscription-status):
 | 
						||
  New endpoint added for checking if another user is subscribed to a stream.
 | 
						||
 | 
						||
**Feature level 11**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added
 | 
						||
  `realm_community_topic_editing_limit_seconds` to the response, the
 | 
						||
  time limit before community topic editing is forbidden.  A `null`
 | 
						||
  value means no limit. This was previously hard-coded in the server
 | 
						||
  as 86400 seconds (1 day).
 | 
						||
* [`POST /register`](/api/register-queue): The response now contains
 | 
						||
  an `is_owner` boolean field, which is similar to the existing
 | 
						||
  `is_admin` and `is_guest` fields.
 | 
						||
* [`POST /typing`](/api/set-typing-status): Removed legacy
 | 
						||
  support for sending email addresses in the `to` parameter, rather
 | 
						||
  than user IDs, to encode direct message recipients.
 | 
						||
 | 
						||
**Feature level 10**
 | 
						||
 | 
						||
* [`GET /users/me`](/api/get-own-user): Added `avatar_version`, `is_guest`,
 | 
						||
  `is_active`, `timezone`, and `date_joined` fields to the User objects.
 | 
						||
* [`GET /users/me`](/api/get-own-user): Removed `client_id` and `short_name`
 | 
						||
  from the response to this endpoint.  These fields had no purpose and
 | 
						||
  were inconsistent with other API responses describing users.
 | 
						||
 | 
						||
**Feature level 9**
 | 
						||
 | 
						||
* [`POST /users/me/subscriptions`](/api/subscribe), [`DELETE
 | 
						||
  /users/me/subscriptions`](/api/unsubscribe): Other users to
 | 
						||
  subscribe/unsubscribe, declared in the `principals` parameter, can
 | 
						||
  now be referenced by user_id, rather than Zulip display email
 | 
						||
  address.
 | 
						||
* [`PATCH /messages/{message_id}`](/api/update-message): Added
 | 
						||
  `send_notification_to_old_thread` and
 | 
						||
  `send_notification_to_new_thread` optional parameters.
 | 
						||
 | 
						||
**Feature level 8**
 | 
						||
 | 
						||
* [`GET /users`](/api/get-users), [`GET /users/{user_id}`](/api/get-user)
 | 
						||
  and [`GET /users/me`](/api/get-own-user): User objects now contain the
 | 
						||
  `is_owner` field as well.
 | 
						||
* [Markdown message formatting](/api/message-formatting#global-times):
 | 
						||
  Added [global times](/help/global-times) to supported message
 | 
						||
  formatting features.
 | 
						||
 | 
						||
**Feature level 7**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): `realm_user` and
 | 
						||
  `realm_bot` events no longer contain an `email` field to identify
 | 
						||
  the user; use the `user_id` field instead.  Previously, some (but
 | 
						||
  not all) events of these types contained an `email` key in addition to
 | 
						||
  to `user_id`) for identifying the modified user.
 | 
						||
* [`PATCH /users/{user_id}`](/api/update-user): The `is_admin` and
 | 
						||
  `is_guest` parameters were removed in favor of the more general
 | 
						||
  `role` parameter for specifying a change in user role.
 | 
						||
* [`GET /events`](/api/get-events): `realm_user` events
 | 
						||
  sent when a user's role changes now include `role` property, instead
 | 
						||
  of the previous `is_guest` or `is_admin` booleans.
 | 
						||
* [`GET /realm/emoji`](/api/get-custom-emoji): The user who uploaded a
 | 
						||
  given custom emoji is now indicated by an `author_id` field, replacing
 | 
						||
  a previous `author` object that had unnecessary additional data.
 | 
						||
 | 
						||
**Feature level 6**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): `realm_user` events to
 | 
						||
  update a user's avatar now include the `avatar_version` field, which
 | 
						||
  is important for correctly refetching medium-size avatar images when
 | 
						||
  the user's avatar changes.
 | 
						||
* [`GET /users`](/api/get-users) and [`GET
 | 
						||
  /users/{user_id}`](/api/get-user): User objects now contain the
 | 
						||
  `avatar_version` field as well.
 | 
						||
 | 
						||
**Feature level 5**
 | 
						||
 | 
						||
* [`GET /events`](/api/get-events): `realm_bot` events,
 | 
						||
  sent when changes are made to bot users, now contain an
 | 
						||
  integer-format `owner_id` field, replacing the `owner` field (which
 | 
						||
  was an email address).
 | 
						||
 | 
						||
**Feature level 4**
 | 
						||
 | 
						||
* `jitsi_server_url`, `development_environment`, `server_generation`,
 | 
						||
  `password_min_length`, `password_min_guesses`, `max_file_upload_size_mib`,
 | 
						||
  `max_avatar_file_size_mib`, `server_inline_image_preview`,
 | 
						||
  `server_inline_url_embed_preview`, `server_avatar_changes_disabled` and
 | 
						||
  `server_name_changes_disabled` fields are now available via
 | 
						||
  `POST /register` to make them accessible to all the clients;
 | 
						||
  they were only internally available to Zulip's web app prior to this.
 | 
						||
 | 
						||
**Feature level 3**
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): `zulip_version` and
 | 
						||
  `zulip_feature_level` are always returned in the endpoint response.
 | 
						||
  Previously, they were only present if `event_types` included
 | 
						||
  `zulip_version`.
 | 
						||
* Added new `presence_enabled` user notification setting; previously
 | 
						||
  [presence](/help/status-and-availability) was always enabled.
 | 
						||
 | 
						||
**Feature level 2**
 | 
						||
 | 
						||
* [`POST /messages/{message_id}/reactions`](/api/add-reaction):
 | 
						||
  The `reaction_type` parameter is optional; the server will guess the
 | 
						||
  `reaction_type` if it is not specified (checking custom emoji, then
 | 
						||
  Unicode emoji for any with the provided name).
 | 
						||
* `reactions` objects returned by the API (both in `GET /messages` and
 | 
						||
  in `GET /events`) now include the user who reacted in a top-level
 | 
						||
  `user_id` field.  The legacy `user` dictionary (which had
 | 
						||
  inconsistent format between those two endpoints) is deprecated.
 | 
						||
 | 
						||
**Feature level 1**
 | 
						||
 | 
						||
* [`PATCH /messages/{message_id}`](/api/update-message): Added the
 | 
						||
  `stream_id` parameter to support moving messages between streams.
 | 
						||
* [`GET /messages`](/api/get-messages), [`GET /events`](/api/get-events):
 | 
						||
  Added `prev_stream` as a potential property of the `edit_history` object
 | 
						||
  within message objects to indicate when a message was moved to another
 | 
						||
  stream.
 | 
						||
* [`GET /messages/{message_id}/history`](/api/get-message-history):
 | 
						||
  `prev_stream` is present in `snapshot` objects within `message_history`
 | 
						||
  object when a message was moved to another stream.
 | 
						||
* [`GET /server_settings`](/api/get-server-settings): Added
 | 
						||
  `zulip_feature_level`, which can be used by clients to detect which
 | 
						||
  of the features described in this changelog are supported.
 | 
						||
* [`POST /register`](/api/register-queue): Added `zulip_feature_level`
 | 
						||
  to the response if `zulip_version` is among the requested
 | 
						||
  `event_types`.
 | 
						||
* [`GET /users`](/api/get-users): User objects for bots now
 | 
						||
  contain a `bot_owner_id`, replacing the previous `bot_owner` field
 | 
						||
  (which had the email address of the bot owner).
 | 
						||
* [`GET /users/{user_id}`](/api/get-user): New endpoint added to get
 | 
						||
  a single user's details by the user's ID.
 | 
						||
* [`GET /messages`](/api/get-messages): Add support for string-format
 | 
						||
  values for the `anchor` parameter, deprecating and replacing the
 | 
						||
  `use_first_unread_anchor` parameter.
 | 
						||
* [`GET /messages`](/api/get-messages), [`GET /events`](/api/get-events):
 | 
						||
  Message objects now use `topic_links` rather than `subject_links` to
 | 
						||
  indicate links either present in the topic or generated by linkifiers
 | 
						||
  applied to the topic.
 | 
						||
* [`GET /streams`](/api/get-streams),
 | 
						||
  [`POST /users/me/subscriptions`](/api/subscribe),
 | 
						||
  [`PATCH /streams/{stream_id}`](/api/update-stream): Stream objects now
 | 
						||
  have `stream_post_policy` enum for specifying who can post to the stream,
 | 
						||
  deprecating and replacing the `is_announcement_only` boolean.
 | 
						||
* [`GET /user_uploads/{realm_id_str}/{filename}`](/api/get-file-temporary-url):
 | 
						||
  New endpoint added for requesting a temporary URL for an uploaded
 | 
						||
  file that does not require authentication to access (e.g., for passing
 | 
						||
  from a Zulip desktop, mobile, or terminal app to the user's default
 | 
						||
  browser).
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events),
 | 
						||
  `PATCH /realm`: Nobody added as an option for the realm setting
 | 
						||
  `email_address_visibility`.
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events),
 | 
						||
  `PATCH /realm`: Added realm setting `private_message_policy`.
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events):
 | 
						||
  `muted_topics` array objects now are 3-item tuples that include the
 | 
						||
  stream name, the topic name, and the time when the topic was muted.
 | 
						||
  Previously, they were 2-item tuples and did not include the time when
 | 
						||
  the topic was muted.
 | 
						||
* [`GET /server_settings`](/api/get-server-settings): Added `gitlab` boolean
 | 
						||
  to deprecated `authentication_methods` object.
 | 
						||
* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events),
 | 
						||
  `PATCH /realm`: None added as an option for the realm setting
 | 
						||
  `video_chat_provider` to disable video call UI.
 | 
						||
 | 
						||
## Changes in Zulip 2.1
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added
 | 
						||
  `realm_default_external_accounts` to endpoint response.
 | 
						||
* [`GET /messages`](/api/get-messages): Added support for
 | 
						||
  [search/narrow options](/api/construct-narrow#changes) that use stream/user
 | 
						||
  IDs to specify a message's sender, its stream, and/or its recipient(s).
 | 
						||
* [`GET /users`](/api/get-users): Added `include_custom_profile_fields`
 | 
						||
  to request custom profile field data.
 | 
						||
* [`GET /users/me`](/api/get-own-user): Added `avatar_url` field,
 | 
						||
  containing the user's avatar URL, to the response.
 | 
						||
* [`GET /users/me/subscriptions`](/api/get-subscriptions): Added
 | 
						||
  `include_subscribers` parameter controlling whether data on the
 | 
						||
  other subscribers is included.  Previous behavior was to always send
 | 
						||
  subscriber data.
 | 
						||
* [`GET /users/me/subscriptions`](/api/get-subscriptions):
 | 
						||
  Stream-level notification settings like `push_notifications` were
 | 
						||
  changed to be nullable boolean fields (true/false/null), with `null`
 | 
						||
  meaning that the stream inherits the organization-level default.
 | 
						||
  Previously, the only values were true/false.  A client communicates
 | 
						||
  support for this feature using `client_capabilities`.
 | 
						||
* [`GET /users/me/subscriptions`](/api/get-subscriptions): Added
 | 
						||
  `wildcard_mentions_notify` notification setting, with the same
 | 
						||
  global-plus-stream-level-override model as other notification settings.
 | 
						||
* [`GET /server_settings`](/api/get-server-settings): Added
 | 
						||
  `external_authentication_methods` structure, used to display login
 | 
						||
  buttons nicely in the mobile apps.
 | 
						||
* Added `first_message_id` field to Stream objects.  This is helpful
 | 
						||
  for determining whether the stream has any messages older than a
 | 
						||
  window cached in a client.
 | 
						||
* Added `is_web_public` field to Stream objects.  This field is
 | 
						||
  intended to support web-public streams.
 | 
						||
* [`GET /export/realm`](/api/get-realm-exports): Added endpoint for
 | 
						||
  fetching public data exports.
 | 
						||
  [`POST /export/realm`](/api/export-realm): Added endpoint for
 | 
						||
  triggering a public data export.
 | 
						||
* `PATCH /realm`: Added `invite_to_stream_policy`,
 | 
						||
  `create_stream_policy`, `digest_emails_enabled`, `digest_weekday`,
 | 
						||
  `user_group_edit_policy`, and `avatar_changes_disabled` organization settings.
 | 
						||
* Added `fluid_layout_width`, `desktop_icon_count_display`, and
 | 
						||
  `demote_inactive_streams` display settings.
 | 
						||
* `enable_stream_sounds` was renamed to
 | 
						||
  `enable_stream_audible_notifications`.
 | 
						||
* [`POST /users/me/subscriptions/properties`](/api/update-subscription-settings):
 | 
						||
  Deprecated `in_home_view`, replacing it with the more readable
 | 
						||
  `is_muted` (with the opposite meaning).
 | 
						||
* Custom profile fields: Added `EXTERNAL_ACCOUNT` field type.
 | 
						||
 | 
						||
## Changes in Zulip 2.0
 | 
						||
 | 
						||
* [`PATCH /users/me/subscriptions/muted_topics`](/api/mute-topic):
 | 
						||
  Added support for using stream IDs to specify the stream in which to
 | 
						||
  mute/unmute a topic.
 | 
						||
* [`POST /messages`](/api/send-message): Added support for using user
 | 
						||
  IDs and stream IDs for specifying the recipients of a message.
 | 
						||
* [`POST /messages`](/api/send-message), [`POST
 | 
						||
  /messages/{message_id}`](/api/update-message): Added support for
 | 
						||
  encoding topics using the `topic` parameter name.  The previous
 | 
						||
  `subject` parameter name was deprecated but is still supported for
 | 
						||
  backwards-compatibility.
 | 
						||
* [`POST /typing`](/api/set-typing-status): Added support for specifying the
 | 
						||
  recipients with user IDs, deprecating the original API of specifying
 | 
						||
  them using email addresses.
 | 
						||
 | 
						||
------------------
 | 
						||
 | 
						||
## Changes not yet stabilized
 | 
						||
 | 
						||
* [`POST /register`](/api/register-queue): Added `slim_presence`
 | 
						||
  parameter.  Changes the format of presence events, but is still
 | 
						||
  being changed and should not be used by clients.
