 All notable changes to the Zulip desktop app are documented in this file.
 
+### v5.9.4 --2023-01-04
+
+**Fixes**:
+
+- The `com.apple.quarantine` extended attribute is now correctly set for downloaded files on macOS.
+- The external link handler ignores invalid URLs.
+
+**Dependencies**:
+
+- Upgraded all dependencies, including Electron 22.0.0.
+
+### v5.9.3 --2022-04-28
+
+**Fixes**:
+
+- Fixed a bug in the automatic updater that would sometimes close the application instead of updating it.
+  (As with most updater fixes, this fix will take effect when updating _from_ 5.9.3. If you're having trouble updating _to_ 5.9.3, a workaround is to click **Install Later** rather than **Install and Relaunch**, then **Quit** from the menu bar and re-open the application manually.)
+
+**Dependencies**:
+
+- Upgraded all dependencies, including Electron 18.2.0.
+
+### v5.9.2 --2022-04-20
+
+**Dependencies**:
+
+- Upgraded all dependencies, including Electron 18.1.0. This fixes an upstream Electron bug that crashed the application when accessibility tools such as screen readers and grammar assistants are in use.
+
+### v5.9.1 --2022-04-08
+
+**Dependencies**:
+
+- Upgraded all dependencies, including Electron 18.0.3.
+
+### v5.9.0 --2022-04-01
+
+**Fixes**:
+
+- Fixed unread count display when viewing a topic with a parenthesized number.
+- Fixed parsing of system proxy settings.
+
+**Enhancements**:
+
+- Removed fade-in animation on page load.
+
+**Dependencies**:
+
+- Upgraded all dependencies, including Electron 18.0.1.
+
+### v5.8.1 --2021-07-29
+
+**Fixes**:
+
+- Downgraded electron-updater to fix automatic updates on macOS.
+  (Note that 5.7.0 and 5.8.0 users may still trigger electron-updater bugs trying to automatically update _to_ 5.8.1; once updated, future updates _from_ 5.8.1 should work correctly.)
+
+### v5.8.0 --2021-07-21
+
+**Fixes**:
+
+- Fixed the spell checker on macOS.
+- Fixed `TypeError` after closing the About page.
+
+**Enhancements**:
+
+- Removed `Ctrl`+`L`/`⌘L` keyboard shortcut to prevent accidental logouts.
+
+**Dependencies**:
+
+- Upgraded all dependencies, including Electron 13.1.7.
+
 ### v5.7.0 --2021-04-30
 
 **Fixes**:
