New features

Percona XtraBackup has removed the multiple binaries (xtrabackup_56, xtrabackup_55, xtrabackup) and now uses single xtrabackup binary instead for handling backups. Single binary implementation removed the requirement to download server source tarballs and removed different patches which resulted in cleaner code.

Percona XtraBackup source layout has been changed to implement the single binary. Percona XtraBackup code can now be found in storage/innobase/xtrabackup.

Percona XtraBackup implemented support for Backup Locks.

Percona XtraBackup can now store backup history on the server itself in a special table created for that purpose.

innobackupex-1.5.1 symlink has been removed, instead innobackupex binary should be used.

Percona XtraBackup has removed the build.sh script and it’s now built with CMake.

Percona XtraBackup has been rebased on MySQL 5.6.16.

Bugs Fixed

Information about tool version used to take the backup was added by implementing backup history feature. Bug fixed #1133017.

If an XtraDB-based binary was used to a backup an InnoDB database, it will convert it to XtraDB by adding the XTRADB_1 marker in the dictionary header page and by adding the SYS_STATS table. Bug fixed #988310.

Other bugs fixed: #721690, #1255899, #1255901, #1268300, and #788316.
