- [ANDROID] [BUGFIX] [DATABASE] - Database listeners now correctly tearing down between RN reloads. (Fixes #1498 #1611 #1609) - [JS] [BUGFIX] [DATABASE] - Fixed an issue where `Reference.toString()` incorrectly contains `//` instead of `/` when joining the parent and child paths. - [JS] [BUGFIX] [DATABASE] - Rework `.push()` behaviour to match WebSDK and correctly return a Reference instance in all scenarios. (Fixes #893 #1464 #1572) - [JS] [ENHANCEMENT] [UTILS] - Added a `firebase.utils().database.cleanup()` utility method which removes all database listeners.
