- **added** — Restored app.setBadgeCount and win.setProgressBar for Linux with support for any dock or taskbar implementing the LauncherEntry D-Bus API without requiring libunity
- **fixed** — Fixed DevTools device metrics overrides persisting indefinitely when a remote debugging client disconnected without clearing them
- **fixed** — Fixed Uncaught illegal access errors and possible renderer crashes after closing a same-process child window or removing an iframe with nodeIntegrationInSubFrames enabled
- **fixed** — Fixed a possible main process crash at quit when a session was created from JavaScript that runs during shutdown
- **fixed** — Fixed a renderer crash when a page calls SpeechRecognition.available() or SpeechRecognition.install() with processLocally
- **fixed** — Fixed crash in sharedTexture module when GPU context becomes unavailable
- **fixed** — Fixed the primary instance being killed or receiving truncated arguments when a second instance passed a very long command line or large additionalData to app.requestSingleInstanceLock()
- **fixed** — Fixed document title updates when using back/forward navigation using the same document without utilizing browserWindow.setTitle()
- **fixed** — Fixed Tray icons not appearing and their menus not opening on Linux desktops that address the StatusNotifierItem by its unique D-Bus name or via the org.freedesktop.StatusNotifierItem interface
- **changed** — Improved performance of file lookups inside ASAR archives and of large files served from them to the renderer
- **changed** — Improved performance of calls through contextBridge-exposed APIs
- **changed** — Improved performance of Buffer.allocUnsafe() and of large file reads in the main and utility processes
- **changed** — Reduced the main-thread cost of sending large values through ipcRenderer, ipcMain handlers and webContents.send
- **changed** — Linux arm64, Windows arm64 and macOS x64 builds now start the main process from the embedded Node.js startup snapshot like the other platforms, improving startup time

* Fixed the primary instance being killed or receiving truncated arguments when a second instance passed a very long command line or large `additionalData` to `app.requestSingleInstanceLock()`. [#52950](https://github.com/electron/electron/pull/52950) 
* Fixeed document title updates when using back/forward navigation using the same document without utilizing `browserWindow.setTitle()`. [#52968](https://github.com/electron/electron/pull/52968) 
##### Other Changes

* Fixed `Tray` icons not appearing (and their menus not opening) on Linux desktops that address the StatusNotifierItem by its unique D-Bus name or via the `org.freedesktop.StatusNotifierItem` interface, such as GNOME with the AppIndicator extension, Cinnamon and XFCE. [#52951](https://github.com/electron/electron/pull/52951) 
* Fixed a stall of tens of milliseconds while creating the first `BrowserWindow` on Linux.
  * Improved the performance of file lookups inside ASAR archives and of large files served from them to the renderer.
  * Improved the performance of calls through `contextBridge`-exposed APIs.
  * Improved the performance of `Buffer.allocUnsafe()` and of large file reads in the main and utility processes.
  * Reduced the main-thread cost of sending large values through `ipcRenderer`, `ipcMain` handlers and `webContents.send`.
