The Apache BookKeeper team is pleased to announce Apache BookKeeper 4.2.3. This is the sixth release of the Apache BookKeeper subproject of ZooKeeper.
The BookKeeper project is made up of a distributed logging service called BookKeeper and a distributed publish/subscribe system build on top of BookKeeper called Hedwig. This is a bugfix release for 4.2.2. Notable fixes and improvements include new utilities to give administrators better visibility of cluster state (BOOKKEEPER-746), improvements to allow for smoother rolling upgrades (BOOKKEEPER-745), fixes to ledger polling to ensure metadata updates aren't missed (BOOKKEEPER-710 & BOOKKEEPER-747) and shading of protobuf libraries to avoid conflicts when included with other version (BOOKKEEPER-708).
