Electron Releases

Added Linux support for app.getApplicationInfoForProtocol(). #51680

Added Notification.remove(), removeAll(), and removeGroup() static methods for macOS. #51691 ^{(Also in 43)}

Added session support to net module requests from utility process. #51698

Fixed DevTools Network panel missing most requests after navigating when webContents.debugger is attached. #51965 ^{(Also in 43)}

Fixed safeStorage.isAsyncEncryptionAvailable() incorrectly reporting false shortly after the app ready event, and a crash when calling safeStorage.encryptStringAsync() or safeStorage.decryptStringAsync() before async encryption initialization completed. safeStorage.isAsyncEncryptionAvailable() now returns a Promise as documented. #51924

Fixed a bug on Linux where a 1px line appeared at the top of frameless windows if the window and web contents had different background colors. #52005 ^{(Also in 41, 43)}

Fixed a renderer crash when calling WebAssembly.compileStreaming() or WebAssembly.instantiateStreaming() with nodeIntegration enabled. #51956 ^{(Also in 43)}

Fixed a browser process crash when calling webContents.reload() or navigating synchronously from the render-process-gone event; the event is now emitted after the renderer's teardown notification has completed. #51916 ^{(Also in 43)}

Fixed an issue on Linux and Windows where frameless windows would shrink when calling win.center(). Additionally, fixed an issue where frameless windows would appear slightly off-center on Windows. #51921 ^{(Also in 41, 43)}

Fixed an issue where the "Toggle Developer Tools" menu item failed to function correctly with BaseWindow. #51903 ^{(Also in 41, 43)}

Fixed sandboxed preload scripts running a stale cached version after the script was modified without its file size changing. #51933 ^{(Also in 43)}

Fixed the context menu in a detached DevTools window focusing the inspected page's window instead of the DevTools window. #51864 ^{(Also in 43)}

Fixed a crash when calling node:wasi functions with fast API calls enabled. #51867

Improved external resize band positioning and scaling for frameless windows on Windows. #51561 ^{(Also in 41, 43)}

Fixed a desktopCapturer crash when sharing a window on Windows. #51787

Fixed an issue where process and other Node globals were undefined in ESM preload scripts when contextIsolation was disabled. #51726 ^{(Also in 43)}

Fixed native addon compilation failure with undefined msvc intrinsic from v8 headers. #51706 ^{(Also in 43)}

Backported fixes from upstream Chromium and V8. #51934

Security: backported fixes for CVE-2026-9115, CVE-2026-9116. #51904

Fixed silent data truncation in Buffer/TextEncoder APIs and a crash in fs.writeFileSync with non-ASCII strings on Apple Silicon. #51849 ^{(Also in 41, 43)}

Improved app startup performance — the main process now boots from an embedded Node.js startup snapshot, framework bundles and preload scripts are cached as compiled V8 bytecode, and sandboxed renderer startup data is pushed ahead of navigation instead of fetched via blocking IPC. Preload stack traces now show the correct file path and line number. #51831 ^{(Also in 43)}

Enabled ThinLTO on macOS builds. #51823 ^{(Also in 43)}

Improved performance of Linux and Windows release builds by enabling ThinLTO link-time optimization for the main Electron binary. #51821 ^{(Also in 43)}
