Percona XtraDB Cluster 5.6.42-28.30 Is Now Available

Percona announces the release of Percona XtraDB Cluster 5.6.42-28.30 (PXC) on January 4, 2019. Binaries are available from the downloads section or our software repositories.

Percona XtraDB Cluster 5.6.42-28.30 is now the current release, based on the following:

• Percona Server 5.6.42
• Codership WSREP API release 5.6.42
• Codership Galera library 3.25

All Percona software is open-source and free.

Fixed Bugs

• PXC-2281: Debug symbols were missing in Debian dbg packages.
• PXC-2220: Starting two instances of Percona XtraDB Cluster on the same node could cause writing transactions to a page store instead of a galera.cache ring buffer, resulting in huge memory consumption because of retaining already applied write-sets.
• PXC-2230: rgcs.fc_limit=0 not allowed as dynamic setting to avoid generating flow control on every message was still possible in my.cnf due to the inconsistent check.
• PXC-2238: setting read_only=1 caused race condition.
