Version 2.5.0
All of room-runtime sources has been converted from Java to Kotlin. Note that you may encounter source incompatibility issues if your code is in Kotlin due to the library conversion to Kotlin. For example, a known source incompatible change is that in InvalidationTracker you will now need to declare onInvalidate() in Observer to have a param of type Set and not MutableSet. Moreover, certain getter methods were converted to properties requiring the property access syntax on Kotlin files. Please file a bug if there are any significant incompatibilities. Added a new shortcut annotation, @Upsert, which attempts to insert an entity when there is no uniqueness conflict or update the entity if there is a conflict. ( I7aaab, b/241964353) New room-paging artifacts room-paging-rxjava2, room-paging-rxjava3 and room-paging-guava have been added for support in Room Paging. Added APIs for providing key and value tables names for disambiguation in @MapInfo ( Icc4b5)
