Bugs fixed

Parallel Applying was not functioning which was evident from the wsrep_cert_deps_distance being 1.0 at all times. Bug fixed #1277703.

Binlog events were created for the statements for non-InnoDB tables, but they were never cleaned from transaction cache, which could lead to node crash. Bug fixed #1277986.

Percona XtraDB Cluster didn’t validate the parameters of wsrep_provider_options when starting it up. Bug fixed #1260193.

clustercheck script would mark node as down on Debian based systems if it was run with default values because it was looking for the defaults-extra-file in the wrong directory. Bug fixed #1276076.

Deadlock would happen when NULL unique key was inserted. Workaround has been implemented to support NULL keys, by using the md5 sum of full row as key value. Bug fixed #1276424.

Variables innodb-log-group-home-dir and innodb-data-home-dir are now handled by default (ie., there is no need to set them up in sst_special_dirs). Bug fixed #1276904.

Builds now use system Zlib instead of bundled one. Bug fixed #1277928.

If transaction size exceeds the wsrep_max_ws_size limit, there will appear a warning message in the error log and replication is skipped. However, the transaction was committed in the master node, and cluster would be in inconsistent state. Bug fixed #1280557.

wsrep_load_data_splitting defaults to OFF now, using it turned ON with autocommit set to 0 is not recommended.

Other bugs fixed: #1279844.
