Breaking Changes
Behavior Changed: macOS notifications now use UNNotification API
Electron has migrated from the deprecated NSUserNotification API to the UNNotification API on macOS. The new API requires that an application be code-signed in order for notifications to be displayed. If an application is not code-signed, notifications will emit a failed event on the Notification object. #47817
Behavior Changed: electron no longer downloads itself via postinstall script
Previously, the electron npm package would download the Electron binary from the repository's GitHub Releases in the package's postinstall script. With recent supply chain security attacks against the npm ecosystem with postinstall scripts as a common attack vector, Electron will now download itself dynamically the first time that its main bin script is run (e.g. via npx electron). See RFC #22 for more context. #49328
Behavior Changed: Offscreen rendering default device scale factor
Previously, OSR used the primary display's device scale factor for rendering. Starting from Electron 42, the default changes to a constant value of 1.0 for more consistent output sizes. Use webPreferences.offscreen.deviceScaleFactor to specify a custom value. #49683
Removed: quotas object from Session.clearStorageData(options)
When calling Session.clearStorageData(options), the options.quotas object is no longer supported because it has been removed from upstream Chromium.
Removed: ELECTRON_SKIP_BINARY_DOWNLOAD environment variable
This environment variable is no longer supported due to the new lazy download behavior. #50459
