+
+### v5.10.3 --2023-09-30
+
+**Fixes**:
+
+- Fixed an error in the third-party `gatemaker` library that broke the display of notifications for completed downloads.
+
+**Dependencies**:
+
+- Upgraded all dependencies, including Electron 25.8.4.
+
+### v5.10.2 --2023-09-14
+
+**Dependencies**:
+
+- Downgraded Electron to 25.8.1 to avoid a renderer process crash on Linux.
+
+### v5.10.1 --2023-09-13
+
+**Dependencies**:
+
+- Upgraded all dependencies, including Electron 26.2.1.
+
+### v5.10.0 --2023-05-05
+
+**Removed features**:
+
+- Removed support for Windows 8.1 and earlier, which reached end-of-life earlier this year and are [no longer supported](https://www.electronjs.org/blog/windows-7-to-8-1-deprecation-notice) by Electron.
+- Removed support for Zulip Server 3.x and earlier, which have been obsolete for more than 18 months, in accordance with our [release lifecycle](https://zulip.readthedocs.io/en/latest/overview/release-lifecycle.html). A notice will now be displayed when connecting to a server with an unsupported version.
+
+**Fixes**:
+
+- Fixed display of the dropdown for the spellchecker languages setting.
+- Fixed various bugs related to displaying and updating organization icons.
+- Fixed settings to disable visual display of notifications.
+
+**Dependencies**:
+
+- Upgraded all dependencies, including Electron 24.2.0.
+
+### v5.9.5 --2023-02-06
+
+**Fixes**:
+
+- Fixed a hang on startup when an organization cannot be connected at startup.
+
+**Enhancements**:
+
+- Enabled Chromium sandboxing in remote renderer processes for improved security hardening.
+
+**Dependencies**:
+
+- Upgraded all dependencies, including Electron 22.2.0.
+
+### 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.)
