New Features

Percona XtraBackup packages are now available for Ubuntu 17.10 (Artful).

xbcrypt now has an ability to decrypt files in parallel by specifying the number of threads with the xtrabackup --encrypt-threads option.

xtrabackup --copy-back option can now be used with xtrabackup :option:–parallel option to copy the user data files in parallel (redo logs :option:and system tablespaces are copied in the main thread).

Bugs fixed

Percona XtraBackup failed to build with GCC 7. Bug fixed #PXB-502.

Percona XtraBackup would crash while preparing the 5.5 backup with utf8_general50_ci collation. Bug fixed #PXB-748 (Fungo Wang).

Percona XtraBackup would crash if xtrabackup --throttle was used while preparing backups. Fixed by making this option available only during the backup process. Bug fixed #PXB-789.

Percona XtraBackup could get stuck if backups are taken with xtrabackup --safe-slave-backup option, while there were long running queries. Bug fixed #PXB-1039.
