This release is the current stable release in the 2.2 series.
Decrypting backup with the wrong key would make the backup unusable and unrecoverable. innobackupex doesn’t automatically delete the *.qp and .xbcrypt files anymore, after innobackupex --decrypt and innobackupex --decompress are used. Bug fixed #1413044.
Fixed Percona XtraBackup assertion caused by dirty pages remaining in the buffer pool after the log was fully applied. Bug fixed #1368846.
Backup will not be prepared and innobackupex will stop with an error if the transaction log file is corrupted and it wasn’t applied to the intended LSN. Previously this was showing only as a warning. Bug fixed #1414221.
New status log-applied is introduced for backup prepared with innobackupex --redo-only to avoid making the backup unusable by preparing full or incremental backup without --redo-only and then applying next incremental on top of it. Incremental backup now can be applied only to backup in log-applied state, but not to full-prepared as it was earlier. Bug fixed #1436790.
