   - `BlockTransaction`: allows creating batch commits of block changes with validation conditions - if any block can't be applied, the whole transaction fails to apply.
   - `ChunkListenerNoOpTrait`: contains default no-op stubs for chunk listener implementations
   - `ChunkListener`: interface allowing subscribing to events happening on a given chunk
+- The following classes have been renamed:
