  14. ## Breaking Changes
  16. * Reduced sandboxed renderer startup work for preload scripts that do not use `Buffer`. [#54048](https://github.com/electron/electron/pull/54048)
  17. * Removed the `events`, `timers` and `url` modules and the `Buffer`, `setImmediate` and `clearImmediate` globals from sandboxed preload scripts; use a polyfill.
  18. * Made sandboxed renderers without a preload script start faster.
  19. * Made sandboxed preload scripts start faster; Electron no longer evaluates a JavaScript bundle of its own in sandboxed renderers unless `webviewTag` is enabled.
  20. * 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.
  21. * 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`.
  22. * The legacy `chromeMediaSource: 'desktop'` constraint now only accepts screen and window source ids from [`desktopCapturer.getSources`](https://github.com/electron/electron/blob/v45.0.0/docs/api/desktop-capturer.md#desktopcapturergetsourcesoptions). 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()`](https://github.com/electron/electron/blob/v45.0.0/docs/api/web-contents.md#contentsgetmediasourceidrequestwebcontents), or use [`ses.setDisplayMediaRequestHandler`](https://github.com/electron/electron/blob/v45.0.0/docs/api/session.md#sessetdisplaymediarequesthandlerhandler-opts).
  23. * 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](https://perfetto.dev/docs/reference/trace-packet-proto).
  24. * Changed heap profiling in `contentTracing` recordings to now use a perfetto heap-profiling data source. [#54863](https://github.com/electron/electron/pull/54863)
  25. * 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](https://github.com/electron/electron/pull/52824)
  26. * Chromium has disabled `document.requestStorageAccessFor` by default ahead of its removal. The API can temporarily be restored with the [`enableBlinkFeatures`](https://github.com/electron/electron/blob/v45.0.0/docs/api/structures/web-preferences.md) web preference set to `RequestStorageAccessFor`. See [Chromium's intent to remove discussion](https://groups.google.com/a/chromium.org/g/blink-dev/c/bqHGZYHWxnQ) for more information.
  27. * `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`.
  28. * 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](https://github.com/electron/electron/pull/52472)
  29. * 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()`.
  30. * 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](https://github.com/electron/electron/pull/52162) <sup>(Also in [44](https://github.com/electron/electron/pull/52397))</sup>
  31. * Clipboard module is now aligned with the W3C Clipboard API. [#51707](https://github.com/electron/electron/pull/51707) <sup>(Also in [44](https://github.com/electron/electron/pull/52508))</sup>
  32. * Removed 32-bit builds (Windows ia32 and Linux armv7l). Electron is now published only for 64-bit (x64 and arm64) platforms. [#51816](https://github.com/electron/electron/pull/51816) <sup>(Also in [44](https://github.com/electron/electron/pull/52326))</sup>
  33. * Removed `openAsHidden` option from `app.setLoginItemSettings()`. [#52351](https://github.com/electron/electron/pull/52351) <sup>(Also in [44](https://github.com/electron/electron/pull/52667))</sup>
  34. * Removed `openAsHidden`, `wasOpenedAsHidden` and `restoreState` fields from return value of `app.getLoginItemSettings()`.
  35. * Fixed potential deadlock inside `app.getLoginItemSettings()` on macOS.
  36. * Updated the Linux support policy. [#52429](https://github.com/electron/electron/pull/52429) <sup>(Also in [44](https://github.com/electron/electron/pull/52538))</sup>
  38. See the [Breaking Changes](https://github.com/electron/electron/blob/v45.0.0/docs/breaking-changes.md) doc for more details about these changes.
  40. ## Features
  42. * 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](https://github.com/electron/electron/pull/50805) <sup>(Also in [43](https://github.com/electron/electron/pull/53045), [44](https://github.com/electron/electron/pull/53046))</sup>
  43. * Added a Save/Restore Window State API for cross-platform use. [#51510](https://github.com/electron/electron/pull/51510) <sup>(Also in [44](https://github.com/electron/electron/pull/52270))</sup>
  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](https://github.com/electron/electron/pull/53851)
  45. * Added app shims on macOS to show windows under another app's Dock icon. [#55072](https://github.com/electron/electron/pull/55072) <sup>(Also in [44](https://github.com/electron/electron/pull/55073))</sup>
  46. * 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`](https://developer.apple.com/documentation/authenticationservices/asauthorizationcontroller?language=objc). [#51563](https://github.com/electron/electron/pull/51563)
  47. * Added `available` to `process.getSystemMemoryInfo()` on Linux, exposing `proc/meminfo` MemAvailable. [#52299](https://github.com/electron/electron/pull/52299) <sup>(Also in [42](https://github.com/electron/electron/pull/52378), [43](https://github.com/electron/electron/pull/52379), [44](https://github.com/electron/electron/pull/52380))</sup>
  48. * Added `disableWakeLocks` option to WebPreferences. [#52342](https://github.com/electron/electron/pull/52342)
  49. * Added `getIsolatedWorlds` method and `isolated-world-created` event for `webFrame` to enable discovery of isolated worlds. [#50633](https://github.com/electron/electron/pull/50633)
  50. * Added `initiatorOrigin` to webRequest and protocol handler requests, `DownloadItem.getInitiatorOrigin()`, and a trailing `frame` argument to the `will-download` and `preconnect` session events. [#53700](https://github.com/electron/electron/pull/53700) <sup>(Also in [43](https://github.com/electron/electron/pull/53704), [44](https://github.com/electron/electron/pull/53703))</sup>
  51. * Added launch-failure reporting with `systemErrorCode` to the `app` `child-process-gone` event. [#54230](https://github.com/electron/electron/pull/54230) <sup>(Also in [44](https://github.com/electron/electron/pull/54231))</sup>
  52. * Added support for `Notification` action buttons on Linux. [#54889](https://github.com/electron/electron/pull/54889) <sup>(Also in [44](https://github.com/electron/electron/pull/54890))</sup>
  53. * Added support for the Prompt API via the new `localAIHandler` module in UtilityProcess. [#50659](https://github.com/electron/electron/pull/50659)
  54. * Added the `ELECTRON_DEBUG_DRAGGABLE_REGIONS` environment variable, which visualizes and logs draggable regions in unpackaged apps to help debug custom title bars. [#53626](https://github.com/electron/electron/pull/53626) <sup>(Also in [43](https://github.com/electron/electron/pull/53633), [44](https://github.com/electron/electron/pull/53627))</sup>
  55. * Added the experimental `protocol.registerSource()` to serve a custom scheme from directories on disk without a JavaScript handler. [#54521](https://github.com/electron/electron/pull/54521) <sup>(Also in [44](https://github.com/electron/electron/pull/54522))</sup>
  56. * Added webContents.caretBrowsingEnabled for toggling caret browsing in a WebContents. [#52696](https://github.com/electron/electron/pull/52696) <sup>(Also in [43](https://github.com/electron/electron/pull/53034), [44](https://github.com/electron/electron/pull/53035))</sup>
  57. * Added `webFrameMain.printToPDF()` to allow printing individual frames to PDF from the main process. [#52439](https://github.com/electron/electron/pull/52439) <sup>(Also in [42](https://github.com/electron/electron/pull/52626), [43](https://github.com/electron/electron/pull/52627), [44](https://github.com/electron/electron/pull/52625))</sup>
  58. * Fixed an issue where `getDisplayMedia({ audio: { restrictOwnAudio: true } })` was ignored in `setDisplayMediaRequestHandler`, causing loopback audio to include local app playback. [#52455](https://github.com/electron/electron/pull/52455) <sup>(Also in [43](https://github.com/electron/electron/pull/52533), [44](https://github.com/electron/electron/pull/52534))</sup>
  59. * Frameless windows on Linux now use system-themed titlebar icons for Window Controls Overlay (WCO). [#52461](https://github.com/electron/electron/pull/52461) <sup>(Also in [44](https://github.com/electron/electron/pull/52531))</sup>
  60. * `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](https://github.com/electron/electron/pull/52833)
  61. * 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](https://github.com/electron/electron/pull/52739) <sup>(Also in [44](https://github.com/electron/electron/pull/52895))</sup>
  62. * 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](https://github.com/electron/electron/pull/52820) <sup>(Also in [44](https://github.com/electron/electron/pull/54204))</sup>
  64. ## Fixes
  66. * `<webview>` and `window.open` now inherit `nodeIntegrationInWorker` from the embedder, consistent with the other Node and sandbox preferences. [#52823](https://github.com/electron/electron/pull/52823) <sup>(Also in [41](https://github.com/electron/electron/pull/52829), [42](https://github.com/electron/electron/pull/52831), [43](https://github.com/electron/electron/pull/52830), [44](https://github.com/electron/electron/pull/52832))</sup>
  67. * `<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](https://github.com/electron/electron/pull/53717) <sup>(Also in [42](https://github.com/electron/electron/pull/53719), [43](https://github.com/electron/electron/pull/53718), [44](https://github.com/electron/electron/pull/53721))</sup>
  68. * Added validation to `protocol.registerSchemesAsPrivileged()` to reject protocol names that do not conform to RFC 3986 URI scheme grammar. [#53742](https://github.com/electron/electron/pull/53742) <sup>(Also in [44](https://github.com/electron/electron/pull/53743))</sup>
  69. * Changed the default trash implementation on KDE Plasma 6 to `kioclient`. [#54362](https://github.com/electron/electron/pull/54362) <sup>(Also in [44](https://github.com/electron/electron/pull/54361))</sup>
  70. * DevTools zoom in/out now uses the same zoom steps as Chromium. [#54388](https://github.com/electron/electron/pull/54388) <sup>(Also in [44](https://github.com/electron/electron/pull/54387))</sup>
  71. * 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](https://github.com/electron/electron/pull/53690) <sup>(Also in [42](https://github.com/electron/electron/pull/53695), [43](https://github.com/electron/electron/pull/53694), [44](https://github.com/electron/electron/pull/53691))</sup>
  72. * Fixed `--xdg-portal-required-version` having no effect and a spurious portal warning being logged for file dialogs on Linux. [#54302](https://github.com/electron/electron/pull/54302) <sup>(Also in [43](https://github.com/electron/electron/pull/54304), [44](https://github.com/electron/electron/pull/54303))</sup>
  73. * Fixed `<select>` dropdowns not rendering in offscreen windows on macOS. [#53716](https://github.com/electron/electron/pull/53716)
  74. * Fixed a 1-in-200 chance per renderer process on Windows of scripts on the first page load being compiled without their V8 code cache. [#52791](https://github.com/electron/electron/pull/52791) <sup>(Also in [42](https://github.com/electron/electron/pull/52988), [43](https://github.com/electron/electron/pull/52943), [44](https://github.com/electron/electron/pull/52792))</sup>
  75. * Fixed a browser process crash that could occur during Windows logoff, shutdown, or restart. [#52604](https://github.com/electron/electron/pull/52604) <sup>(Also in [42](https://github.com/electron/electron/pull/52621), [43](https://github.com/electron/electron/pull/52620), [44](https://github.com/electron/electron/pull/52619))</sup>
  76. * Fixed a browser-process crash (`ValidateIntegrityOrDie`) and spurious preload `ENOENT` errors when an app's `app.asar` is replaced on disk (e.g. by an updater or MDM software) while the app is running. [#52283](https://github.com/electron/electron/pull/52283) <sup>(Also in [42](https://github.com/electron/electron/pull/52294), [43](https://github.com/electron/electron/pull/52293), [44](https://github.com/electron/electron/pull/52292))</sup>
  77. * Fixed a bug where content-protected windows could temporarily appear in screen captures during picture-in-picture state changes. [#54612](https://github.com/electron/electron/pull/54612)
  78. * Fixed a child `WebContentsView` losing focus when its window is reactivated. [#54454](https://github.com/electron/electron/pull/54454) <sup>(Also in [43](https://github.com/electron/electron/pull/54456), [44](https://github.com/electron/electron/pull/54455))</sup>
  79. * Fixed a crash in `systemPreferences.promptTouchID(reason)` when an invalid reason value is passed. [#52764](https://github.com/electron/electron/pull/52764) <sup>(Also in [42](https://github.com/electron/electron/pull/52780), [43](https://github.com/electron/electron/pull/52782), [44](https://github.com/electron/electron/pull/52781))</sup>

  82. * 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. [#53022](https://github.com/electron/electron/pull/53022) <sup>(Also in [42](https://github.com/electron/electron/pull/53094), [43](https://github.com/electron/electron/pull/53095), [44](https://github.com/electron/electron/pull/53096))</sup>
  83. * Fixed a crash on macOS when a notification's icon could not be attached; the notification is now shown without the icon. [#53131](https://github.com/electron/electron/pull/53131) <sup>(Also in [42](https://github.com/electron/electron/pull/53148), [43](https://github.com/electron/electron/pull/53147), [44](https://github.com/electron/electron/pull/53146))</sup>

  275. * Improved the performance of building and showing menus. [#53914](https://github.com/electron/electron/pull/53914)
  276. * Improved the performance of `fs` operations and `require()` on files inside asar archives. [#53919](https://github.com/electron/electron/pull/53919) <sup>(Also in [44](https://github.com/electron/electron/pull/54051))</sup>

  278. * Improved throughput of responses that `protocol.handle` handlers return straight from `net.fetch`. [#53379](https://github.com/electron/electron/pull/53379) <sup>(Also in [44](https://github.com/electron/electron/pull/53378))</sup>
  279. * Page resources, `fetch()` calls and file:// loads in renderers no longer wait for the main process to be idle when no `webRequest` listeners or protocol interceptors are registered. [#53115](https://github.com/electron/electron/pull/53115) <sup>(Also in [42](https://github.com/electron/electron/pull/53143), [43](https://github.com/electron/electron/pull/53142), [44](https://github.com/electron/electron/pull/53141))</sup>

  281. * Reduced the macOS distribution size by shipping only the locale strings that Electron can actually use. [#52290](https://github.com/electron/electron/pull/52290)
  282. * Renderer network requests no longer waited on the main process when the session's `webRequest` listeners only observe requests (`onCompleted`, `onErrorOccurred`, `onSendHeaders`, `onBeforeRedirect`, `onResponseStarted`) or are filtered to other resource types. [#53204](https://github.com/electron/electron/pull/53204) <sup>(Also in [44](https://github.com/electron/electron/pull/53240))</sup>
  283. * The first sandboxed `BrowserWindow` now starts in a renderer process launched ahead of time when the default session already exists, shortening the time from window creation to the page's first script; apps that open many windows can keep a spare renderer warm at all times with `--enable-features=SpareRendererForSitePerProcess`. [#53116](https://github.com/electron/electron/pull/53116) <sup>(Also in [44](https://github.com/electron/electron/pull/53144))</sup>
