Percona XtraBackup 2.1.7 发布，此版本包括了一些新特性和一些 bug 修复。更新内容如下：

新特性：

• Percona XtraBackup has now been rebased on MySQL versions 5.1.73, 5.5.35, 5.6.15 and Percona Server versions 5.1.73-rel14.11 and 5.5.35-rel33.0.

Bug 修复：

• After being rebased on MySQL 5.6.11 Percona XtraBackup has been affected by the upstream bug #69780. Fixed by rebasing Percona XtraBackup on MySQL 5.6.15 which contains a fix for the upstream bug. Bug fixed #1203669.

• Backup directory would need to be specified even for running the innobackupex with --help and --version options. Bug fixed #1223716.

• When creating an incremental backup with the changed page tracking feature available in Percona Server, innobackupexwould fail if the server had the ANSI_QUOTES SQL mode enabled. Bug fixed #1248331.

• When innobackupex --galera-info is specified and Percona XtraDB Cluster is using GTID replication (version 5.6 only),innobackupex will execute FLUSH BINARY LOGS and then carry the current binary log as indicated in SHOW MASTER STATUSinto the backup set. Bug fixed #1250375.

• Percona XtraBackup did not roll back prepared XA transactions when applying the log. Which was a regression introduced with the original port of Percona XtraBackup patches to 5.6. Fixed by restoring code that has been lost in the port. Bug fixed #1254227.

• Percona XtraBackup now uses libgcrypt built in randomization functions for setting the Initialization Vector. Bug fixed#1255300.

• xtrabackup_56 didn’t support ALL_O_DIRECT option for innodb_flush_method in Percona Server 5.6. Bug fixed #1261877.

其他 bug 修复： #1255019, #1268325, #1265759, #1269694, #1271501.
