Percona XtraBackup 2.2.10 发布，此版本现已提供在下载页面和 Percona Software Repositories。
此版本主要是 bug 修复：
Decrypting backup with the wrong key would make the backup unusable and unrecoverable. Bug fixed #1413044.
XtraDB Changed Page Tracking wasn’t working with innobackupex. Bug fixed #1436793.
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 --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.
