Release Notes: This release brings much enhanced core dedupe logic that improves performance, chunking, and matching accuracy, and implements a K-Min-Values (MinHash) sketch for similarity matching. Delta Compression extent is now user-selectable. Support for FIxed-Block dedupe has been added. Adaptive compression modes now use a heuristic for significant speedup, reduced memory use, and have become much more practical to use. There are several bugfixes.
