Bugs Fixed
Node eviction in the middle of SST now causes the node to shut down properly.
After an error during node startup, the state is now marked unsafe only if SST is required.
Fixed data inconsistency during multi-insert auto-increment workload on async master with binlog-format=STATEMENT when a node begins async slave with wsrep_auto_increment_control=ON.
Fixed crash when a prepare statement is aborted (due to conflict with applier) and then replayed.
Removed a special case condition in wsrep_recover() that whould not happen under normal conditions.
Percona XtraDB Cluster no longer fails during SST, if a node reserves a very large amount of memory for InnoDB buffer pool.
If the value of wsrep_cluster_address is not valid, trying to create a slave thread will now generate a warning instead of an error, and the thread will not be created.
Fixed error with loading data infile (LDI) into a multi-partitioned table.
The wsrep_node_name variable now defaults to host name.
Starting mysqld with unknown option now fails with a clear error message, instead of randomly crashing.
Optimized the operation of SST and IST when a node fails during startup.
The wsrep_desync variable can now be enabled only after a node is synced with cluster. That is, it cannot be set during node bootup configuration).
Fixed crash when setting a high flow control limit (fc_limit) and the recv queue fills up.
Only the default 16 KB page size (innodb_page_size=16384) is accepted until the relevant upstream bug is fixed by Codership (see All other sizes will report Invalid page size and shut down (the server will not start up).
If a node is executing RSU/FTWRL, explicit desync of the node will not happen until the implicit desync action is complete.
Fixed multiple bugs in test suite to improve quality assurance.
