 |Percona XtraBackup| 2.2.6
============================

Percona is glad to announce the release of |Percona XtraBackup| 2.2.6 on November 3rd 2014. Downloads are available from our download site `here <http://www.percona.com/downloads/XtraBackup/2.2.6/>`_ and from :ref:`apt <apt_repo>` and :ref:`yum <yum_repo>` repositories. 

This release is the current stable release in the 2.2 series.

New Features
------------

 |Percona XtraBackup| now reads server options from ``SHOW VARIABLES`` rather than :file:`my.cnf` configuration file. 

 |Percona XtraBackup| now has more verbose output during initial table scan (it will now print a diagnostic message before performing a tablespace scan, which may take a long time on systems with large numbers of tablespaces) and before starting a backup/apply-log/copy-back operation in innobackupex (it will now print a diagnostic message with a timestamp to make it easier for users to get duration of the operation.)

Bugs Fixed
----------

 |innobackupex| didn't take the default datadir, which caused backups to fail if the datadir wasn't specified in the :file:`my.cnf` configuration file. Bug fixed :bug:`936934`.

 |innobackupex| will now fail with an error when :option:`innobackupex --slave-info` is used on  a multi-threaded non-GTID slave, because ``Exec_Master_Log_Pos`` cannot be trusted for a multi-threaded slave. Bug fixed :bug:`1372679`.

 InnoDB log scanning failure (bug :mysqlbug:`60788`) would cause backups to fail. Fixed by porting the fix from |MySQL| 5.7. Bug fixed :bug:`1375383`.  

 Options :option:`innobackupex --apply-log` and :option:`innobackupex --decompress` weren't marked as mutually exclusive, ie. if they were both specified, only :option:`innobackupex --decompress` would work, which could lead to |MySQL| instance being started with an unprepared backup. Fixed by making mutually exclusive categories of options: 1. :option:`innobackupex --decompress`, :option:`innobackupex --decrypt`; 2. :option:`innobackupex --copy-back`; 3. :option:`innobackupex --move-back`; 4. :option:`innobackupex --apply-log`. Bug fixed :bug:`1376874`.

 |innobackupex| wasn't creating directories specified in :option:`innodb_data_home_dir` and :option:`innodb_log_group_home_dir` when :option:`innobackupex --copy-back` option was used. Bug fixed :bug:`1382347`.

 |Percona XtraBackup| now supports all option modifiers supported by upstream MySQL: skip, disable, enable, maximum, loose. Bug fixed :bug:`664128`.

 |Percona Xtrabackup| would fail to perform a full backup on |Percona Server| 5.5 if :option:`innodb_log_file_size` variable wasn't set in the ``[mysqld]`` section of :file:`my.cnf`. Bug fixed :bug:`1334062`. 

Other bugs fixed: :bug:`1379905`, :bug:`1386013`, :bug:`1072695`, :bug:`1375241`, :bug:`1182841`, and :bug:`1343722`.
