破壊的変更​

Removed: macOS 11 support​

macOS 11 (Big Sur) is no longer supported by Chromium.

Older versions of Electron will continue to run on Big Sur, but macOS 12 (Monterey) or later will be required to run Electron v38.0.0 and higher.

Removed: ELECTRON_OZONE_PLATFORM_HINT environment variable​

The default value of the --ozone-plaftform flag changed to auto.

You should use the XDG_SESSION_TYPE=wayland environment variable instead to use Wayland.

Removed: plugin-crashed event​

The plugin-crashed event has been removed from webContents.

Deprecated: webFrame.routingId property​

The routingId property will be removed from webFrame objects.

You should use webFrame.frameToken instead.

Deprecated: webFrame.findFrameByRoutingId(routingId)​

The webFrame.findFrameByRoutingId(routingId) function will be removed.

You should use webFrame.findFrameByToken(frameToken) instead.

Google Summer of Code Concludes​

Our two Google Summer of Code contributors have just completed their summer projects!

  • @nilayarya crafted a new Save/Restore Window State API in Electron core. The new APIs will provide a built-in, standardized way to handle window state persistence. See Nilay's original RFC at electron/rfcs#16.
  • @hitarth-gg put a lot of hard work into modernizing the long-dormant Devtron extension using Chrome Manifest V3 APIs. This project provides tooling for developers to debug IPC communication, track event listeners, and visualize module dependencies in their Electron applications.

Stay tuned for a more detailed blog post outlining their projects and the outcomes.
