Notable Changes​

Stack Changes​

Electron 39 upgrades Chromium from 140.0.7339.41 to 142.0.7444.52, Node.js from 22.18.0 to v22.20.0, and V8 from 14.0 to 14.2.

ASAR Integrity graduates to stable​

A long-standing "experimental" feature -- ASAR integrity -- is now stable in Electron 39. When you enable this feature, it validates your packaged app.asar at runtime against a build-time hash to detect any tampering. If no hash is present or if there is a mismatch in the hashes, the app will forcefully terminate.

See the ASAR integrity documentation for full information on how on the feature works, on how to use it in your application, and how to use it in Electron Forge and Electron Packager.

In related news, Electron Packager v19 now enables ASAR by default. #1841

Deprecated: --host-rules command line switch​

Chromium is deprecating the --host-rules switch.

You should use --host-resolver-rules instead.

Behavior Changed: window.open popups are always resizable​

Per current WHATWG spec, the window.open API will now always create a resizable popup window.

To restore previous behavior:

webContents.setWindowOpenHandler((details) => {
  return {
    action: 'allow',
    overrideBrowserWindowOptions: {
      resizable: details.features.includes('resizable=yes'),
    },
  };
});

Behavior Changed: shared texture OSR paint event data structure​

When using the shared texture offscreen rendering feature, the paint event now emits a more structured object. It moves the sharedTextureHandle, planes, modifier into a unified handle property. See the OffscreenSharedTexture documentation for more details.
