This is an General Availability release. We did our best to eliminate bugs and problems during alpha and beta testing release, but this is a software, so bugs are expected. If you encounter them, please report them to our bug tracking system.
Based on Percona Server 5.5.23-25.3 including all the bug fixes in it, and the latest Galera 2.x replicator, Percona XtraDB Cluster 5.5.23-25.3 is now the current stable release. All of Percona‘s software is open-source and free.
For general inquiries, please send us your question and someone will contact you.
