Electron Releases

Fixes

• Fixed DevTools device metrics overrides persisting indefinitely when a remote debugging client disconnected without clearing them. #52946 ^{(Also in 42, 44)}

• Fixed BrowserWindow.unmaximize() and restore() having no effect on Wayland when the window was maximized immediately after creation. #53125 ^{(Also in 42, 44)}

• Fixed fs.constants.O_DIRECTORY, O_NOFOLLOW and O_DIRECT holding x86 values on Linux arm64 and armv7l, which made opening a directory fail with EINVAL, and made require('trace_events') behave the same on cross-compiled builds as on native ones. #53319 ^{(Also in 42, 44, 45)}

• Fixed webContents.executeJavaScriptInIsolatedWorld resolving with undefined when worldId was not an integer. #53237 ^{(Also in 44)}

• Fixed webContents.print() honoring printBackground, duplexMode, and printer default duplex settings. #53160 ^{(Also in 42, 44)}

• Fixed a crash on Linux when the D-Bus session bus disconnected while the app was running, such as at logout or when dbus is restarted. #53095 ^{(Also in 42, 44)}

• Fixed a crash on Windows when V8 posted a delayed worker task during shutdown. #53013 ^{(Also in 42, 44)}

• Fixed a crash on macOS when a WebAuthn Touch ID prompt was requested while no locale resources were loaded. #53195 ^{(Also in 44)}

• Fixed a crash on macOS when a notification's icon could not be attached; the notification is now shown without the icon. #53147 ^{(Also in 42, 44)}

• Fixed a crash when calling node:wasi functions in optimized code. #53265 ^{(Also in 42, 44, 45)}

• Fixed a crash when calling utilityProcess.postMessage() after the utility process had exited. #53301 ^{(Also in 44, 45)}

• Fixed a regression where a window created with a custom title can show an empty title after using back/forward navigation. #53219 ^{(Also in 42, 44)}

• Fixed a renderer crash when a page calls SpeechRecognition.available() or SpeechRecognition.install() with processLocally. #53015 ^{(Also in 42, 44)}

• Fixed an issue where pages loaded in a detached WebContentsView wouldn't see the correct window size. #53152 ^{(Also in 42, 44)}

• Fixed crashes in sharedTexture, service-worker ipcRenderer and utilityProcess.fork() caused by object lifetime bugs. #53278 ^{(Also in 44, 45)}

• Fixed crashes in the main process when a webRequest.onBeforeRequest listener redirected a CORS preflight request, and when calling net.fetch() with a webRequest-permission extension loaded. #53304 ^{(Also in 44, 45)}

• Fixed crashes when a webContents or parent window is destroyed while other APIs still reference it. #53288 ^{(Also in 44, 45)}

• Fixed crashes when certain app event handlers call back into Electron synchronously. #53276 ^{(Also in 44, 45)}

• Fixed document title updates when using back/forward navigation using the same document without utilizing browserWindow.setTitle(). #53023 ^{(Also in 42, 44)}

• Fixed region-qualified --lang values such as de-DE loading no locale resources on macOS, which left localized strings empty and could crash WebAuthn Touch ID prompts. #53186 ^{(Also in 42, 44)}

• Fixed spellcheck not initializing on Linux when the dictionary was already cached from a previous run. #52717 ^{(Also in 44)}

• Fixed the GPU process being terminated in AppX/MSIX packaged apps on Windows when WebGPU fell back to SwiftShader. #53197 ^{(Also in 42, 44)}

• 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(). #53156 ^{(Also in 42, 44)}

• Fixed the tray icon not appearing on GNOME (and disappearing entirely on Wayland) since 43.4.1. #53215

• Fixed utility process crashes at exit on Windows 11 24H2 and later. #53092 ^{(Also in 42, 44)}
