Breaking Changes

• breaking

  Reduced sandboxed renderer startup work for preload scripts that do not use Buffer. #54048

  • Removed the events, timers and url modules and the Buffer, setImmediate and clearImmediate globals from sandboxed preload scripts; use a polyfill.

  • Made sandboxed renderers without a preload script start faster.

  • Made sandboxed preload scripts start faster; Electron no longer evaluates a JavaScript bundle of its own in sandboxed renderers unless webviewTag is enabled.

• breaking

  With nodeIntegrationInWorker: true, a Worker created from an <iframe> in the same process as the main frame used to get Node.js integration even though the iframe itself had none. Workers now only get Node.js integration when the frame that creates them has it: the main frame, or any frame when nodeIntegrationInSubFrames is enabled.

• breaking

  A chrome-extension:// document used to receive the window's preload script (and session preload scripts) wherever it was embedded. It now only does so when it is a top-level frame or is hosted inside the DevTools front-end (a devtools_page or panel); an extension frame embedded in an ordinary page is treated like any other subframe and follows nodeIntegrationInSubFrames.

• breaking

  The legacy chromeMediaSource: 'desktop' constraint now only accepts screen and window source ids from desktopCapturer.getSources. Passing a WebContents source id there now fails with an "Invalid state" error. To capture a WebContents, use chromeMediaSource: 'tab' with an id from webContents.getMediaSourceId(), or use ses.setDisplayMediaRequestHandler.

• breaking

  The experimental contentTracing.enableHeapProfiling() API has been removed. Chromium removed the memlog implementation that backed this API and replaced it with a Perfetto heap-profiling data source. Pass a nativeHeapProfiling option to contentTracing.startRecording() to enable heap profiling for the duration of a trace. Like all recordings, heap-enabled recordings use the Perfetto protobuf format.

• breaking

  Changed heap profiling in contentTracing recordings to now use a perfetto heap-profiling data source. #54863

• breaking

  Screen, window and tab capture requests are now reported to setPermissionRequestHandler as display-capture instead of media; a handler that allows only media must also allow display-capture to keep screen sharing working. #52824

• breaking

  Chromium has disabled document.requestStorageAccessFor by default ahead of its removal. The API can temporarily be restored with the enableBlinkFeatures web preference set to RequestStorageAccessFor. See Chromium's intent to remove discussion for more information.

• breaking

  fs.open, fs.openSync and fs.promises.open on a file inside an ASAR archive used to extract the file to a temporary copy and return a descriptor for that copy. They now return a descriptor that only identifies the entry to Node's fs module, which reads directly out of the archive with no temporary file (fs.read, fs.readv, fs.fstat, fs.readFile(fd), fs.createReadStream and the FileHandle methods). The descriptor itself is not backed by the file's contents: code that reads the raw descriptor (a native addon, child_process stdio, net.Socket({ fd }), http2stream.respondWithFile() / respondWithFD(), a FileHandle transferred to a worker, ...) fails with EBADF and is not supported. Opening a file inside an archive with a flag that allows writing (w, a, r+, ...) now fails with EACCES instead of silently writing to the temporary copy, and fs.fchmod, fs.fchown and fs.futimes on these descriptors fail with EACCES.

• breaking

  A window.open() child whose sandbox state differs from its opener's renderer process is now created in its own process with no opener relationship instead of silently sharing the opener's process; set sandbox: false in setWindowOpenHandler to keep sharing an unsandboxed opener's process. #52472

• breaking

  The synchronous safeStorage methods are deprecated and will be removed in Electron 46, following Chromium's removal of the synchronous OSCrypt backend they are built on. Use the asynchronous methods instead, which use the same per-platform key stores. Data encrypted with safeStorage.encryptString() can be decrypted with safeStorage.decryptStringAsync().

• breaking

  Added select-client-certificate event support for net.request and net.fetch; requests to servers requesting a client certificate no longer fail with ERR_SSL_CLIENT_AUTH_CERT_NEEDED, and applications can now select a certificate to present. #52162 (Also in 44)

• breaking

  Clipboard module is now aligned with the W3C Clipboard API. #51707 (Also in 44)

• breaking

  Removed 32-bit builds (Windows ia32 and Linux armv7l). Electron is now published only for 64-bit (x64 and arm64) platforms. #51816 (Also in 44)

• breaking

  Removed openAsHidden option from app.setLoginItemSettings(). #52351 (Also in 44)

  • Removed openAsHidden, wasOpenedAsHidden and restoreState fields from return value of app.getLoginItemSettings().

  • Fixed potential deadlock inside app.getLoginItemSettings() on macOS.

• breaking

  Updated the Linux support policy. #52429 (Also in 44)

See the Breaking Changes doc for more details about these changes.

Features

• Added a badge property to MenuItem on macOS 14+ for showing a count or custom text badge next to a menu item's label. #50805 (Also in 43, 44)

• Added a Save/Restore Window State API for cross-platform use. #51510 (Also in 44)

• Added a Windows Error Reporting helper (electron_wer.dll, renamed to <app>_wer.dll alongside the executable) so crashReporter captures __fastfail and other crashes that bypass the in-process handler on Windows. #53851

• Added app shims on macOS to show windows under another app's Dock icon. #55072 (Also in 44)

• Added app.configureWebAuthn() API to enable iCloud Keychain passkey support on macOS. When enabled, navigator.credentials.create() and .get() present Apple's native passkey UI via ASAuthorizationController. #51563

• Added available to process.getSystemMemoryInfo() on Linux, exposing proc/meminfo MemAvailable. #52299 (Also in 42, 43, 44)

• Added disableWakeLocks option to WebPreferences. #52342

• Added getIsolatedWorlds method and isolated-world-created event for webFrame to enable discovery of isolated worlds. #50633

• Added initiatorOrigin to webRequest and protocol handler requests, DownloadItem.getInitiatorOrigin(), and a trailing frame argument to the will-download and preconnect session events. #53700 (Also in 43, 44)

• Added launch-failure reporting with systemErrorCode to the app child-process-gone event. #54230 (Also in 44)

• Added support for Notification action buttons on Linux. #54889 (Also in 44)

• Added support for the Prompt API via the new localAIHandler module in UtilityProcess. #50659

• Added the experimental protocol.registerSource() to serve a custom scheme from directories on disk without a JavaScript handler. #54521 (Also in 44)

• Added webContents.caretBrowsingEnabled for toggling caret browsing in a WebContents. #52696 (Also in 43, 44)

• Fixed an issue where getDisplayMedia({ audio: { restrictOwnAudio: true } }) was ignored in setDisplayMediaRequestHandler, causing loopback audio to include local app playback. #52455 (Also in 43, 44)

• Frameless windows on Linux now use system-themed titlebar icons for Window Controls Overlay (WCO). #52461 (Also in 44)

• fs.open, fs.createReadStream, fs.copyFile, fs.cp and friends now read files inside ASAR archives directly from the archive instead of extracting a temporary copy; fs.opendir and fs.readlink work on archives; opening a packed file for writing fails with EACCES. #52833

• Restored app.setBadgeCount and win.setProgressBar for Linux. These APIs now support any dock or taskbar which implements the LauncherEntry D-Bus API, and they no longer require libunity. #52739 (Also in 44)

• The macOS autoUpdater now streams update downloads to disk, resumes an interrupted download on the next check instead of starting over, and applies a binary delta when the update feed offers one for the running version. #52820 (Also in 44)

Fixes

• <webview> and window.open now inherit nodeIntegrationInWorker from the embedder, consistent with the other Node and sandbox preferences. #52823 (Also in 41, 42, 43, 44)

• <webview> without allowpopups also blocks links opened into a new window by modifier-click, and such windows navigate as the clicking document rather than as a browser-initiated load. #53717 (Also in 42, 43, 44)

• Added validation to protocol.registerSchemesAsPrivileged() to reject protocol names that do not conform to RFC 3986 URI scheme grammar. #53742 (Also in 44)

• Changed the default trash implementation on KDE Plasma 6 to kioclient. #54362 (Also in 44)

• DevTools zoom in/out now uses the same zoom steps as Chromium. #54388 (Also in 44)

• File System Access permission requests and the file-system-access-restricted event are scoped to the requesting document, grants are reset when the origin's last page closes, and write access works in in-memory sessions. #53690 (Also in 42, 43, 44)

• Fixed --xdg-portal-required-version having no effect and a spurious portal warning being logged for file dialogs on Linux. #54302 (Also in 43, 44)
