+#### Highlights

+- New Inbox view shows all unread messages in a conveniently
+  browsable experience, similar to the mobile home screen.

+  notification settings for followed topics and flexible configuration
+  options to automatically follow topics when sending a message or
+  otherwise interacting with it.
+- (Incomplete) New @topic mentions support mentioning only users who
+  have participated in a topic.

+  into corresponding Zulip markup. Improved pasting URLs with text
