BLOBvalues for a compressed table. This regression was introduced in Percona Server 5.5.28-29.2. Bug fixed #1100159 (Laurynas Biveinis).
DROP TABLEperformance were not adjusted for XtraDB. This could cause server assertion errors. Bugs fixed #934377, bug #1111211, bug #1116447 and #1110102 (Laurynas Biveinis).
innodb_flush_method=O_DIRECTwas set up, log bitmap files were created and treated as InnoDB data files for flushing purposes, which wasn’t original intention. Bug fixed #1105709 (Laurynas Biveinis).
INFORMATION_SCHEMAplugin name innodb_changed_pages serves also as a command line option, but it is also a prefix of another command line option innodb_changed_pages_limit. MySQL option handling would then shadow the former with the latter, resulting in start up errors. Fixed by renaming the innodb_changed_pages_limit option to innodb_max_changed_pages. Bug fixed #1105726 (Laurynas Biveinis).
AIOroutines if large innodb_log_block_size value is used in the combination with changed page tracking. Bug fixed #1114612 (Laurynas Biveinis).
