Bugs Fixed:

The buffer pool mutex split patch implemented in Percona Server could cause a race condition, involving a dirty compressed page block for which there is an uncompressed page image in the buffer pool, that could lead to a server crash. Bug fixed #1086680.

The buffer pool mutex split patch implemented in Percona Server could cause server crash with an assertion error on read-write workloads with compressed tables in debug builds. Bug fixed #1103850.

If binary log was enabled, Fake Changes transactions were binlogged. This could lead to data corruption issues with deeper replication topologies. Bug fixed #1190580.

Changes made to the RPM scripts for previous Percona Server version caused installer to fail if there were different datadir options in multiple configuration files. Bug fixed #1201036.

Percona Server used to acquire the buffer pool LRU list mutex in the I/O completion routine for the compressed page flush list flushes where it was not necessary. Bug fixed #1181269.

Other bug fixes: bug fixed #1188162 and bug fixed #1203308.
