注目すべき変更

Writing Tools Support

In Electron 36, you can enable macOS system-level features like Writing Tools (spelling and grammar), Autofill, and Services menu items in your context menus. To do so, pass a WebFrameMain instance into the frame parameter for menu.popup().

import { BrowserWindow, Menu, WebFrameMain } from 'electron';

const currentWindow = BrowserWindow.getFocusedWindow();
const focusedFrame = currentWindow.webContents.focusedFrame;
const menu = Menu.buildFromTemplate([{ label: 'Copy', role: 'copy' }]);

menu.popup({
  window: currentWindow,
  frame: focusedFrame,
});

破壊的変更

Deprecated: NativeImage.getBitmap()

The NativeImage.getBitmap() function is now deprecated and documented as an alias for NativeImage.toBitmap(). The two functions both return a newly-allocated copy of the bitmap and are functionally equivalent.

Deprecated: Extension methods and events on session

session.loadExtension, session.removeExtension, session.getExtension, session.getAllExtensions, and the events extension-loaded, extension-unloaded, and extension-ready have all moved to the new Extensions object accessible via the session.extensions instance property.

Removed: quota type syncable in session.clearStorageData(options)

When calling session.clearStorageData(options), the options.quota type syncable is no longer supported because it has been removed from upstream Chromium.

Deprecated: quota property in session.clearStorageData(options)

When calling Session.clearStorageData(options), the options.quota property is deprecated. Since the syncable type was removed, there is only type left -- 'temporary' -- so specifying it is unnecessary.

Behavior Changed: GTK 4 is the default when running on GNOME

After an upstream change, GTK 4 is now the default when running on GNOME.

In rare cases, this may cause some applications or configurations to error with the following message:

Gtk-ERROR **: 11:30:38.382: GTK 2/3 symbols detected. Using GTK 2/3 and GTK 4 in the same process is not supported

Affected users can work around this by specifying the gtk-version command-line flag:

$ electron --gtk-version=3   # or --gtk-version=2

The same can be done with the app.commandLine.appendSwitch function.

Behavior Changed: app.commandLine

app.commandLine will convert uppercases switches and arguments to lowercase.

app.commandLine was only meant to handle Chromium switches (which aren't case-sensitive) and switches passed via app.commandLine will not be passed down to any of the child processes.

If you were using app.commandLine to parse app-specific command line arguments, you should do this via process.argv.

33.x.y サポートの終了

プロジェクトの サポートポリシー に則り、Electron 33.x.y はサポート終了を迎えました。 開発者とアプリケーションは新しいバージョンの Electron にアップグレードすることを推奨します。

E36 (Apr'25)	E37 (Jun'25)	E38 (Aug'25)
36.x.y	37.x.y	38.x.y
35.x.y	36.x.y	37.x.y
34.x.y	35.x.y	36.x.y

次回予告

短期的には、Chromium、Node、V8 といった Electron を構成する主要コンポーネントの開発に遅れないでチームが注力し続けるでしょう。
