When Percona XtraBackup would run
FLUSH ENGINE LOGSduring the backup process on GTID master, command was recorded to the slave’s binary log as well。Bug fixed #1394632.
Exporting tables was inefficient when backup contained a large (and unrelated) change buffer. Bug fixed #1366065 (Davi Arnaut).
innobackupex was printing the GTID even if the GTID mode was disabled which could cause confusion since it wasn’t incrementing. Bug fixed #1391041.
其他 bug 修复：bug #1386157.
