Bugs Fixed
INSTALL PLUGIN statement would crash server if User Statistics were enabled. Bug fixed #1011047.
Running top-level make would fail while running autoreconf in UDF subdirectory if the Automake version was 1.13. Bug fixed #1244110.
Server would fail to build with GCC 4.8 in build configurations that have the MySQL maintainer mode enabled. Bugs fixed #1244154 (upstream bug #68909) and #1186190 (upstream bug #69407).
PURGE CHANGED_PAGE_BITMAPS BEFORE statement would delete the changed page data after the specified LSN and up to the start of the next bitmap file. If this data were to be used for fast incremental backups, its absence would cause Percona XtraBackup to fall back to the full-scan incremental backup mode. Bug fixed #1260035 (Andrew Gaul).
