  11. ## Breaking Changes
  13. ### Behavior Changed: macOS notifications now use `UNNotification` API
  15. 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](https://github.com/electron/electron/pull/47817)
  17. ### Behavior Changed: `electron` no longer downloads itself via `postinstall` script
  19. 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](https://github.com/electron/rfcs/pull/22) for more context. [#49328](https://github.com/electron/electron/pull/49328)
  21. ### Behavior Changed: Offscreen rendering default device scale factor
  23. 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](https://github.com/electron/electron/pull/49683)
  25. ### Removed: `quotas` object from `Session.clearStorageData(options)`
  27. When calling `Session.clearStorageData(options)`, the `options.quotas` object is no longer supported because it has been removed from upstream Chromium.
  29. ### Removed: `ELECTRON_SKIP_BINARY_DOWNLOAD` environment variable
  31. This environment variable is no longer supported due to the new lazy download behavior. [#50459](https://github.com/electron/electron/pull/50459)
  33. ## Features
  35. ### Additions
  37. * Added `app.configureWebAuthn({ touchID: { keychainAccessGroup } })` to enable the WebAuthn Touch ID platform authenticator on macOS.
