Bugs 修复：

• Percona XtraBackup was vulnerable to MITM attack which could allow exfiltration of MySQL configuration information via --version-check option. This vulnerability was logged as CVE 2015-1027. Bug fixed #1408375.

• xtrabackup_galera_info file isn’t overwritten during the Galera auto-recovery. Bug fixed #1418584.

• Percona XtraBackup man pages are now included with binary packages. Bug fixed #1156209.

• Percona XtraBackup now sets the maximum supported session value for lock_wait_timeout variable to prevent unnecessary timeouts when the global value is changed from the default. Bug fixed #1410339.

• New option --backup-locks, enabled by default, has been implemented to control if backup locks will be used even if they are supported by the server. To disable backup locks innobackupex should be run with innobackupex --no-backup-locks option. Bug fixed #1418820.
