重要变化​

Smooth Corners: Native CSS Squircles​

An image showing different corner smoothing values (0%, 30%, 60%, and 100%) applied to rectangles, with 60% labeled as matching macOS style

Electron 37 introduces the custom -electron-corner-smoothing CSS property, which allows apps to create smoother rounded corners to match Apple's macOS design language. This feature originally landed in Electron 36, but we felt like it deserved a brighter spotlight.

Example with 100% Corner Smoothing

代码结果
.box {
  width: 128px;
  height: 128px;
  border-radius: 24px;
  -electron-corner-smoothing: 100%;
}

Unlike the standard border-radius property, which carves quarter-circle corners out of a rectangle, -electron-corner-smoothing smoothly transitions the curve into a squircle shape with a continuous perimeter.

You can adjust the smoothness using values from 0% to 100%, or use the system-ui value to match the operating system's style (60% on macOS and 0% otherwise). This design enhancement can be applied on borders, outlines, and shadows, giving your app a subtle layer of polish.

提示

Read more about Electron's squircle implementation in @clavin's RFC 0012. The document goes over the motivation and technical implementation in more detail.

The initial design drew inspiration from Figma's corner smoothing implementation. Read more about their own quest for smooth corners in "Desperately seeking squircles".

架构（Stack）更新​

Electron 37 upgrades Chromium from 136.0.7103.48 to 138.0.7204.35, and V8 from 13.6 to 13.8.

Google Summer of Code Begins​

Our two Google Summer of Code contributors have started the program's coding period!

  • @nilayarya is crafting 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 in-progress RFC at electron/rfcs#16.
  • @hitarth-gg is hard at work modernizing the long-dormant Devtron extension using Chrome Manifest V3 APIs. This project will provide tooling for developers to debug IPC communication, track event listeners, and visualize module dependencies in their Electron applications.

It has been an exciting couple of weeks for our GSOC participants, so stay tuned for more updates!

New Features and Improvements​

  • Added innerWidth and innerHeight options for window.open. #47039 (Also in 35, 36)
  • Added before-mouse-event to allow intercepting and preventing mouse events in webContents. #47364 (Also in 36)
  • Added scriptURL property to ServiceWorkerMain. #45863
  • Added sublabel functionality for menus on macOS >= 14.4. #47042 (Also in 35, 36)
  • Added support for HIDDevice.collections. #47483 (Also in 36)
  • Added support for --no-experimental-global-navigator flag. #47418 (Also in 35, 36)
  • Added support for screen.dipToScreenPoint(point) and screen.screenToDipPoint(point) on Linux X11. #46895 (Also in 35, 36)
  • Added support for menu item role palette and header on macOS. #47245
  • Added support for node option --experimental-network-inspection. #47031 (Also in 35, 36)
  • Exposed win.isContentProtected() to allow developers to check window protection status. #47310 (Also in 36)

重大更改​

Utility Process unhandled rejection behavior change​

Utility Processes will now warn with an error message when an unhandled rejection occurs instead of crashing the process.

To restore the previous behavior, you can use:

process.on('unhandledRejection', () => {
  process.exit(1);
});

Behavior Changed: process.exit() kills utility process synchronously​

Calling process.exit() in a utility process will now kill the utility process synchronously. This brings the behavior of process.exit() in line with Node.js behavior.

Please refer to the Node.js docs and PR #45690 to understand the potential implications of that, e.g., when calling console.log() before process.exit().

Behavior Changed: WebUSB and WebSerial Blocklist Support​

WebUSB and Web Serial now support the WebUSB Blocklist and Web Serial Blocklist used by Chromium and outlined in their respective specifications.

To disable these, users can pass disable-usb-blocklist and disable-serial-blocklist as command line flags.

Removed: null value for session property in ProtocolResponse​

This deprecated feature has been removed.

Previously, setting the ProtocolResponse.session property to null would create a random independent session. This is no longer supported.

Using single-purpose sessions here is discouraged due to overhead costs; however, old code that needs to preserve this behavior can emulate it by creating a random session with session.fromPartition(some_random_string) and then using it in ProtocolResponse.session.

Behavior Changed: BrowserWindow.IsVisibleOnAllWorkspaces() on Linux​

BrowserWindow.IsVisibleOnAllWorkspaces() will now return false on Linux if the window is not currently visible.

终止对 34.x.y 的支持​

根据项目的支持政策，Electron 34.x.y 已经达到了支持的终点。 我们鼓励开发者将应用程序升级到更新的 Electron 版本。
