Highlighted Features
UtilityProcess API #36089
The new UtilityProcess main process module allows the creation of a lightweight Chromium child process with only Node.js integration while also allowing communication with a sandboxed renderer using MessageChannel. The API was designed based on Node.js child_process.fork to allow for easier transition, with one primary difference being that the entry point modulePath must be from within the packaged application to allow only for trusted scripts to be loaded. Additionally the module prevents establishing communication channels with renderers by default, upholding the contract in which the main process is the only trusted process in the application.

Windows 7/8/8.1 Support Update
2023/02/16: An update on Windows Server 2012 support
Last month, Google announced that Chrome 109 would continue to receive critical security fixes for Windows Server 2012 and Windows Server 2012 R2 until October 10, 2023. In accordance, Electron 22's (Chromium 108) planned end of life date will be extended from May 30, 2023 to October 10, 2023. The Electron team will continue to backport any security fixes that are part of this program to Electron 22 until October 10, 2023.
Note that we will not make additional security fixes for Windows 7/8/8.1. Also, Electron 23 (Chromium 110) will only function on Windows 10 and above as previously announced.
Electron 22 will be the last Electron major version to support Windows 7/8/8.1. Electron follows the planned Chromium deprecation policy, which will deprecate Windows 7/8/8.1 support in Chromium 109 (read more here).
Windows 7/8/8.1 will not be supported in Electron 23 and later major releases.

Критические изменения в API
Below are breaking changes introduced in Electron 22. You can read more about these changes and future changes on the Planned Breaking Changes page.
Obsoleto: webContents.incrementCapturerCount(stayHidden, stayAwake)
webContents.incrementCapturerCount(stayHidden, stayAwake) has been deprecated. It is now automatically handled by webContents.capturePage when a page capture completes.
const w = new BrowserWindow({ show: false })
- w.webContents.incrementCapturerCount()
- w.capturePage().then(image => {
- console.log(image.toDataURL())
- w.webContents.decrementCapturerCount()
- })
+ w.capturePage().then(image => {
+ console.log(image.toDataURL())
+ })
Obsoleto: webContents.decrementCapturerCount(stayHidden, stayAwake)
webContents.decrementCapturerCount(stayHidden, stayAwake) has been deprecated. It is now automatically handled by webContents.capturePage when a page capture completes.
const w = new BrowserWindow({ show: false })
- w.webContents.incrementCapturerCount()
- w.capturePage().then(image => {
- console.log(image.toDataURL())
- w.webContents.decrementCapturerCount()
- })
+ w.capturePage().then(image => {
+ console.log(image.toDataURL())
+ })
Removed: WebContents new-window event
The new-window event of WebContents has been removed. Заменяется на webContents.setWindowOpenHandler().
- webContents.on('new-window', (event) => {
- event.preventDefault()
- })
+ webContents.setWindowOpenHandler((details) => {
+ return { action: 'deny' }
+ })
Deprecated: BrowserWindow scroll-touch-* events
The scroll-touch-begin, scroll-touch-end and scroll-touch-edge events on BrowserWindow are deprecated. Instead, use the newly available input-event event on WebContents.
// Deprecated
- win.on('scroll-touch-begin', scrollTouchBegin)
- win.on('scroll-touch-edge', scrollTouchEdge)
- win.on('scroll-touch-end', scrollTouchEnd)
// Replace with
+ win.webContents.on('input-event', (_, event) => {
+ if (event.type === 'gestureScrollBegin') {
+ scrollTouchBegin()
+ } else if (event.type === 'gestureScrollUpdate') {
+ scrollTouchEdge()
+ } else if (event.type === 'gestureScrollEnd') {
+ scrollTouchEnd()
+ }
+ })
