NEW FEATURES
Percona XtraBackup has been rebased on MySQL 5.6.24.
BUGS FIXED
Version check would crash innobackupex and abort the backup on CentOS 5. Bug fixed #1255451.
Percona XtraBackup could crash when preparing the backup taken on MySQL/Percona Server 5.5 if there were open temporary tables during the backup. Bug fixed #1399471 (Fungo Wang).
Percona XtraBackup would fail to prepare the backup if the xtrabackup_logfile was lager than 512GB. Bug fixed #1425269.
Fix for bug #1403237 was incomplete, due to setting wrong offset, last copied batch of log records was copied from wrong location. Bug fixed #1448447.
Percona XtraBackup now executes an extra FLUSH TABLES before executing FLUSH TABLES WITH READ LOCK to potentially lower the impact from FLUSH TABLES WITH READ LOCK. Bug fixed #1277403.
Regression introduced by fixing #1436793 in Percona XtraBackup 2.2.10 caused an error when taking an incremental backup from MariaDB 10. Bug fixed #1444541.
Percona XtraBackup now prints and stores the file based binlog coordinates in xtrabackup_binlog_info even though GTID is enabled. Bug fixed #1449834.
Percona XtraBackup doesn’t print warnings anymore during the prepare phase about missing tables when a filtering option (--databases, --tables, etc.) is provided. Bug fixed #1454815 (Davi Arnaut).
