Breaking Changes​

Removed: macOS 10.15 support​

macOS 10.15 (Catalina) is no longer supported by Chromium.

Older versions of Electron will continue to run on Catalina, but macOS 11 (Big Sur) or later will be required to run Electron v33.0.0 and higher.

Behavior Changed: Native modules now require C++20​

Due to changes made upstream, both V8 and Node.js now require C++20 as a minimum version. Developers using native node modules should build their modules with --std=c++20 rather than --std=c++17. Images using gcc9 or lower may need to update to gcc10 in order to compile. See #43555 for more details.

Behavior Changed: custom protocol URL handling on Windows​

Due to changes made in Chromium to support Non-Special Scheme URLs, custom protocol URLs that use Windows file paths will no longer work correctly with the deprecated protocol.registerFileProtocol and the baseURLForDataURL property on BrowserWindow.loadURL, WebContents.loadURL, and <webview>.loadURL. protocol.handle will also not work with these types of URLs but this is not a change since it has always worked that way.

// No longer works
protocol.registerFileProtocol('other', () => {
  callback({ filePath: '/path/to/my/file' });
});
const mainWindow = new BrowserWindow();
mainWindow.loadURL(
  'data:text/html,<script src="loaded-from-dataurl.js"></script>',
  { baseURLForDataURL: 'other://C:\\myapp' },
);
mainWindow.loadURL('other://C:\\myapp\\index.html');
// Replace with
const path = require('node:path');
const nodeUrl = require('node:url');
protocol.handle(other, (req) => {
  const srcPath = 'C:\\myapp\\';
  const reqURL = new URL(req.url);
  return net.fetch(
    nodeUrl.pathToFileURL(path.join(srcPath, reqURL.pathname)).toString(),
  );
});
mainWindow.loadURL(
  'data:text/html,<script src="loaded-from-dataurl.js"></script>',
  { baseURLForDataURL: 'other://' },
);
mainWindow.loadURL('other://index.html');

Behavior Changed: webContents property on login on app​

The webContents property in the login event from app will be null when the event is triggered for requests from the utility process created with respondToAuthRequestsFromMainProcess option.

Deprecated: textured option in BrowserWindowConstructorOption.type​

The textured option of type in BrowserWindowConstructorOptions has been deprecated with no replacement. This option relied on the NSWindowStyleMaskTexturedBackground style mask on macOS, which has been deprecated with no alternative.

Deprecated: systemPreferences.accessibilityDisplayShouldReduceTransparency​

The systemPreferences.accessibilityDisplayShouldReduceTransparency property is now deprecated in favor of the new nativeTheme.prefersReducedTransparency, which provides identical information and works cross-platform.

// Deprecated
const shouldReduceTransparency =
  systemPreferences.accessibilityDisplayShouldReduceTransparency;
// Replace with:
const prefersReducedTransparency = nativeTheme.prefersReducedTransparency;

End of Support for 30.x.y​

Electron 30.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.
