 ## Breaking changes coming soon
 
-in an upcoming major release - see [`xpbrew/cordova-sqlite-storage#922`](https://github.com/xpbrew/cordova-sqlite-storage/issues/922):
+in an upcoming major release - see [`xpbrew/cordova-sqlite-storage#922`](https://github.com/xpbrew/cordova-sqlite-storage/issues/922)
+
+some highlights:
 
 - drop support for Android pre-5.1, which will also be dropped by `cordova-android`, including deprecated `armeabi` target (superseded by `armeabi-v7a`, seems to be not supported by Android 5.0) - more info in [`xpbrew/cordova-sqlite-storage#922`](https://github.com/xpbrew/cordova-sqlite-storage/issues/922)
 - error `code` will always be `0` (which is already the case on Windows); actual SQLite3 error code will be part of the error `message` member whenever possible (see [`xpbrew/cordova-sqlite-storage#821`](https://github.com/xpbrew/cordova-sqlite-storage/issues/821))
 - drop support for location: 0-2 values in openDatabase call (please use `location: 'default'` or `iosDatabaseLocation` setting in openDatabase as documented below)
+- throw an exception in case of `androidDatabaseImplementation: 2` setting which is now superseded by `androidDatabaseProvider: 'system'` setting
+
+under consideration:
+
+- remove `androidLockWorkaround: 1` option if not needed any longer - [`xpbrew/cordova-sqlite-storage#925`](https://github.com/xpbrew/cordova-sqlite-storage/issues/925)
