 * Non-Blocking Manual Compaction (CompactRange()) - Support non-blocking manual compactions by setting a new CompactRangeOptions option (async_completion_cb). When set, the CompactRange() call will return control to the caller immediately. The manual compaction iteslf will be performed in an internally created thread. The manual compaction will ALWAYS call the specified callback upon completion and provide the completion status (#597).
 
 ### Enhancements
+* Unit Testing: Expose the disallow_trivial_move flag in the MoveFilesToLevel testing utility (#677).
 
 ### Bug Fixes
 db_bench: fix SeekRandomWriteRandom valid check. Use key and value only after checking iterator is valid.
