Bug fixes

• PXC-3583: Fixed an issue where the validate-config tool incorrectly reported that ssl-ca, ssl-cert, and ssl-key must all be defined to use encrypted traffic.

• PXC-4753: Fixed an issue where Percona audit log filter execution did not sync across Percona XtraDB Cluster nodes, although the audit log filter synced correctly on async or Group Replication replicas when executed on their source.

• PXC-4765: Fixed an issue where creating a trigger with a definer caused an inconsistency error and disconnected the node from the cluster.

• PXC-4802: Fixed a misleading “Initiating SST cancellation” log message that was printed during fatal signal handling.

• PXC-4814: Fixed an issue where OPTIMIZE TABLE failed when wsrep_OSU_method was set to RSU (Rolling Schema Update), due to case-sensitive writes to the binary log with error_code=0.

• PXC-4823: Fixed an issue where an asynchronous Percona XtraDB Cluster replica stalled when replicating OPTIMIZE TABLE.

• PXC-4845: Fixed an issue where a node remained up and running after an Incremental State Transfer (IST) failure, which could cause other nodes in the cluster to become unresponsive.
