注目すべき変更​

macOS notifications now use UNNotification API​

Electron has migrated from the deprecated NSUserNotification API to the UNNotification API on macOS. The new API requires that an application be code-signed in order for notifications to be displayed. If an application is not code-signed, notifications will emit a failed event on the Notification object. #47817

Additionally, Electron 42 adds Notification.getHistory() for macOS (#51123), and id and groupId options to the Notification constructor to allow custom identifiers and visual grouping in Notification Center (#50304).

electron no longer downloads itself via postinstall script​

Previously, the electron npm package would download the Electron binary from the repository's GitHub Releases in the package's postinstall script. With recent supply chain security attacks against the npm ecosystem with postinstall scripts as a common attack vector, Electron will now download itself dynamically the first time that its main bin script is run (e.g. via npx electron). With this change, you can now use Electron with the npm --ignore-scripts flag. See RFC #22 for more context. #49328

If you need to download the Electron binary on-demand, you can now call the install-electron script:

npm install electron --save-dev --ignore-scripts
npx install-electron

WebAuthn Touch ID support on macOS​

Added app.configureWebAuthn({ touchID: { keychainAccessGroup } }) to enable the WebAuthn Touch ID platform authenticator on macOS. This also introduces a select-webauthn-account session event for discoverable-credential selection. #51411

View animations and background blur​

Added animation functionality to view.setBounds() and added view.setBackgroundBlur(), allowing for smoother UI transitions and native background blur effects. #48812

破壊的変更​

Behavior Changed: macOS notifications now use UNNotification API​

Electron has migrated from the deprecated NSUserNotification API to the UNNotification API on macOS. The new API requires that an application be code-signed in order for notifications to be displayed. If an application is not code-signed, notifications will emit a failed event on the Notification object. #47817

Behavior Changed: electron no longer downloads itself via postinstall script​

With recent supply chain security attacks against the npm ecosystem with postinstall scripts as a common attack vector, Electron will now download itself dynamically the first time that its main bin script is run (e.g. via npx electron). See RFC #22 for more context. #49328

Behavior Changed: Offscreen rendering default device scale factor​

Previously, OSR used the primary display's device scale factor for rendering. Starting from Electron 42, the default changes to a constant value of 1.0 for more consistent output sizes. Use webPreferences.offscreen.deviceScaleFactor to specify a custom value. #49683

Removed: quotas object from Session.clearStorageData(options)​

When calling Session.clearStorageData(options), the options.quotas object is no longer supported because it has been removed from upstream Chromium.

Removed: ELECTRON_SKIP_BINARY_DOWNLOAD environment variable​

This environment variable is no longer supported due to the new lazy download behavior. #50459

Deprecated: Passing only an array hslShift to nativeImage.createFromNamedImage()​

Passing only an array hslShift to nativeImage.createFromNamedImage() is deprecated. You should now pass an options object with an hslShift property instead:

// Deprecated
nativeImage.createFromNamedImage(imageName, [0, 1, -1]);
// Replace with
nativeImage.createFromNamedImage(imageName, {
  hslShift: [0, 1, -1],
});

39.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 39.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。 サポートされているバージョンの Electron のタイムラインについては、https://releases.electronjs.org/schedule を参照してください。

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。
