 All notable changes to the Zulip desktop app are documented in this file.
 
+### v5.5.0 --2020-12-01
+
+**Removed features**:
+* Removed legacy handling of custom certificates. Custom certificates can be configured in the same system certificate store that Chrome uses ([instructions](https://zulip.com/help/custom-certificates#desktop)).
+* Removed the unmaintained notification inline replies feature on macOS. We believe the `node-mac-notifier` library used by this feature had been responsible for the grey screen crash issue.
+
+**Fixes**:
+* Fixed a regression with the factory reset function.
+* Fixed the grey screen crash issue on macOS ([#1016](https://github.com/zulip/zulip-desktop/issues/1016)).
+* Whitespace is now stripped from the organization URL when adding a new organization.
+
+**Dependencies**:
+* Upgraded all dependencies, including Electron 11.0.3.
+
+### v5.4.3 --2020-09-10
+
+**Security fixes**:
+* CVE-2020-24582: Escape all strings interpolated into HTML to close cross-site scripting vulnerabilities that a malicious server could exploit.
+
+**Dependencies**:
+* Upgrade dependencies, including Electron 9.3.0.
+
+### v5.4.2 --2020-08-12
+
+**Dependencies**:
+* Upgrade all dependencies, including Electron 9.2.0.
+
+### v5.4.1-beta --2020-07-29
+
+**Fixes**:
+* Resized the large application icon on macOS dock to be coherent with other icons.
+
+**Dependencies**:
+* Upgrade all dependencies, including Electron 9.1.1.
+
+### v5.4.0 --2020-07-21
+
+**New features**:
+* Added support for certificates from system store.
+* Added support for Slovak as application language.
+
+**Fixes**:
+* Fix bug in *Copy Link* and add *Copy Email* option in context menu.
+* Enable *Copy* option in context menu only when copying is possible.
+* Remove leading and trailing separators in context menu on non-mac systems.
+* ignoreCerts: Accommodate WebSocket URLs in certificate-error handler.
+
+**Dependencies**:
+* Upgrade all dependencies, including Electron 8.4.0.
+
+**Deprecations**:
+* This release supports certificates from Zulip store as well as system store. Zulip certificate store will be deprecated in the next release.
+Users are hereby requested to move to system store. For more information, please see the [documentation](https://zulip.com/help/custom-certificates).
