Notable Changes​

Improved app startup performance​

Electron 43 ships several improvements to app startup performance. The main process now boots from an embedded Node.js startup snapshot, framework bundles and preload scripts are cached as compiled V8 bytecode, and sandboxed renderer startup data is pushed ahead of navigation instead of fetched via blocking IPC. As a bonus, preload stack traces now show the correct file path and line number. #51792

Frameless windows on Linux now have rounded corners by default​

On Linux, frameless windows now have rounded corners by default, matching the behavior on macOS and Windows. Rounded corners can be disabled on all platforms by setting roundedCorners: false on the window. #52111

File downloads now open in the Downloads folder by default​

File downloads will now open by default in the user's Downloads folder (or the Home directory if Downloads doesn't exist). #49868

New macOS Notification management APIs​

Electron 43 adds Notification.remove(), Notification.removeAll(), and Notification.removeGroup() static methods on macOS, giving developers finer control over delivered notifications. Combined with the existing Notification.getHistory() API, you can now fully manage the lifecycle of notifications in Notification Center. #51690

Stack Changes​

Electron 43 upgrades Chromium from 148.0.7778.96 to 150.0.7871.46, Node.js from v24.15.0 to v24.17.0, and V8 from 14.8 to 15.0.

  • Added JS stack trace to crash reports on renderer OOM. #50043
  • Added Linux support for app.getApplicationInfoForProtocol(). #51297
  • Added Notification.remove(), Notification.removeAll(), and Notification.removeGroup() static methods for macOS. #51690

  • Improved performance of app.getApplicationNameForProtocol() on Linux. #51251
  • Improved performance of app.isDefaultProtocolClient() and app.setAsDefaultProtocolClient() on Linux. #51316
  • Improved performance of webRequest header conversions and several other gin converter hot paths. #51608

Breaking Changes​

Behavior Changed: File downloads now open in the Downloads folder​

File downloads will now open by default in the user's Downloads folder (or the Home directory if the Downloads folder doesn't exist). #49868

Behavior Changed: nativeImage pixel values are normalized to SRGB​

If a nativeImage was passed an image with a color profile, its pixel values will now be normalized to SRGB. This ensures that two visually identical images after color space application will receive similar pixel values when converted to a nativeImage. #51565

Behavior Changed: Frameless windows have rounded corners on Linux by default​

On Linux, frameless windows now have rounded corners by default, matching the behavior on macOS and Windows. Rounded corners can be disabled on all platforms by setting roundedCorners: false on the window. #52111

Behavior Changed: WCO respects the native title bar layout on Linux​

Frameless windows with Window Controls Overlay (WCO) now adopt the native title bar layout and user settings on Linux. For example, controls will appear on the left side of the frame on RTL systems, and only the close button will be visible by default on GNOME. Depending on the user's desktop environment and configuration, buttons can appear on the left or right side of the frame (or both). To account for all possibilities, use the CSS variables env(titlebar-area-x, 0px) and env(titlebar-area-width, 100%) to constrain your app's title bar content to a safe area. #52018

Behavior Changed: chrome.scripting CSS injection matches more fallback frames​

Extensions using chrome.scripting.insertCSS() or chrome.scripting.removeCSS() now follow Chrome's behavior when Electron cannot match a frame's URL directly, such as with about:blank or data: frames. If the extension has access to the page that created the frame, CSS may now be inserted into or removed from those fallback frames as well. Apps or extensions that relied on Electron skipping those frames should narrow their injection target, frame IDs, or match patterns. #51376

Removed: showHiddenFiles from dialog API on Linux​

showHiddenFiles support has been removed from the dialog API on Linux. #51880

End of Support for 40.x.y​

Electron 40.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. See https://releases.electronjs.org/schedule to see the timeline for supported versions of Electron.

Support for 32-bit platforms ending​

Electron 43.x.y will be the last version series of Electron to ship with prebuilt binaries for 32-bit platforms: Windows x86 (win32-ia32) and Linux ARM (linux-armv7l). Once the v43 series reaches end of life in January 2027, these 32-bit platforms will no longer be supported.

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.
