Percona is glad to announce the latest stable release of Percona XtraBackup 1.6.7 on December 20th, 2012 (Downloads are available here).
This release is purely composed of bug fixes to the previous stable release of Percona XtraBackup. New users should head for Percona XtraBackup 2.0 rather than 1.6.
--remote-hostoptions. Bugs fixed #723318 and #787988 (Stewart Smith).
FLUSH TABLES WITH READ LOCKwas not used when creating incremental backups, which could lead to inconsistent backups when updates to non-InnoDB tables or DDL statements on any tables occurred during the backup process. Bug fixed #771981 (Alexey Kopytov).
--safe-slave-backupwas resulting in incorrect binlog info, because in some cases innobackupex confused the response from
SHOW SLAVE STATUSwith the one from
SHOW MASTER STATUS. Bug fixed #977101 (Alexey Kopytov).
--apply-log, it was reading configuration from the server configuration file instead of backup-my.cnf in backup directory. Bug fixed #996493 (Sergei Glushchenko).
--backup. This was fixed by reusing the existing file descriptor so no leak occurs. Bug fixed #713267 (Alexey Kopytov).
The full release notes and details about fixed bugs are available in the release notes.
