Notable Changes​

Highlights​

  • ASAR Integrity fuse now supported on Windows (#40504)
    • Existing apps with ASAR Integrity enabled may not work on Windows if not configured correctly. Apps using Electron packaging tools should upgrade to @electron/packager@18.3.1 or @electron/forge@7.4.0.
    • Take a look at our ASAR Integrity tutorial for more information.
  • Added WebContentsView and BaseWindow main process modules, deprecating & replacing BrowserView (#35658)
    • BrowserView is now a shim over WebContentsView and the old implementation has been removed.
    • See our Web Embeds documentation for a comparison of the new WebContentsView API to other similar APIs.
  • Implemented support for the File System API (#41827)

Stack Changes​

New Features​

  • Added a new instance property navigationHistory on webContents API with navigationHistory.getEntryAtIndex method, enabling applications to retrieve the URL and title of any navigation entry within the browsing history. (#41662)
  • Added new BrowserWindow.isOccluded() method to allow apps to check occlusion status. (#38982)
  • Added proxy configuring support for requests made with the net module from the utility process. (#41417)

Breaking Changes​

Behavior Changed: cross-origin iframes now use Permission Policy to access features​

Cross-origin iframes must now specify features available to a given iframe via the allow attribute in order to access them.

See documentation for more information.

Removed: The --disable-color-correct-rendering command line switch​

This switch was never formally documented but its removal is being noted here regardless. Chromium itself now has better support for color spaces so this flag should not be needed.

Behavior Changed: BrowserView.setAutoResize behavior on macOS​

In Electron 30, BrowserView is now a wrapper around the new WebContentsView API.

Previously, the setAutoResize function of the BrowserView API was backed by autoresizing on macOS, and by a custom algorithm on Windows and Linux. For simple use cases such as making a BrowserView fill the entire window, the behavior of these two approaches was identical. However, in more advanced cases, BrowserViews would be autoresized differently on macOS than they would be on other platforms, as the custom resizing algorithm for Windows and Linux did not perfectly match the behavior of macOS's autoresizing API. The autoresizing behavior is now standardized across all platforms.

If your app uses BrowserView.setAutoResize to do anything more complex than making a BrowserView fill the entire window, it's likely you already had custom logic in place to handle this difference in behavior on macOS. If so, that logic will no longer be needed in Electron 30 as autoresizing behavior is consistent.

Removed: params.inputFormType property on context-menu on WebContents​

The inputFormType property of the params object in the context-menu event from WebContents has been removed. Use the new formControlType property instead.

Removed: process.getIOCounters()​

Chromium has removed access to this information.

End of Support for 27.x.y​

Electron 27.x.y has reached end-of-support as per the project's support policy. Developers and applications are encouraged to upgrade to a newer version of Electron.

What's Next​

In the short term, you can expect the team to continue to focus on keeping up with the development of the major components that make up Electron, including Chromium, Node, and V8.
