[LIST]
[]PXC-889: Fixed an issue where a node with an invalid value for wsrep_provider was allowed to start up and operate in standalone mode, which could lead to data inconsistency. The node will now abort in this case. Bug fixed #1728774.
[]Ensured that a node, because of data inconsistency, isolates itself before leaving the cluster, thus allowing pending nodes to re-evaluate the quorum. Bug fixed #1704404.
[]PXC-875: Fixed an issue where toggling wsrep_provider off and on failed to reset some internal variables and resulted in PXC logging an “Unsupported protocol downgrade” warning. Bug fixed #1379204.
[]PXC-883: Fixed ROLLBACK TO SAVEPOINT incorrect operation on slaves by avoiding useless wsrep plugin register for a savepoint rollback. Bug fixed #1700593.
[]PXC-887: gcache .page files were unnecessarily created due to an error in projecting gcache free size when configured to recover on restart.
[]Fixed transaction loss after recovery by avoiding interruption of the binlog recovery based on wsrep saved position. Bug fixed #1734113.
[]Fixed empty gtid_executed variable after recovering the position of a node with --wsrep_recover.
[]Fixed certification failure in the case of a node restarting at the same time when frequent TRUNCATE TABLE commands and DML writes occur simultaneously on other nodes. Bug fixed #1737731.
[]PXC-914: Suppressing DDL/TOI replication in case of sql_log_bin zero value didn’t work when DDL statement was modifying an existing table, resulting in an error.
