* **Deprecated:** An API was marked as deprecated. The API will continue to function, but will emit a deprecation warning, and will be removed in a future release.
* **Removed:** An API or feature was removed, and is no longer supported by Electron.
## Planned Breaking API Changes (23.0)
### Removed: BrowserWindow `scroll-touch-*` events
The deprecated `scroll-touch-begin`, `scroll-touch-end` and `scroll-touch-edge`
events on BrowserWindow have been removed. Instead, use the newly available
[`input-event` event](api/web-contents.md#event-input-event) on WebContents.
