New Features
Packages are now available for Ubuntu 17.10 (Artful).
xbcrypt now can decrypt files in parallel by specifying the number of threads with the --encrypt-threads option.
Percona XtraBackup --copy-back option can now be used with --parallel option to copy the user data files in parallel (redo logs and system tablespaces are copied in the main thread).
Bugs Fixed:
Percona XtraBackup failed to build with GCC 7. Bug fixed #1681721.
Percona XtraBackup would crash while preparing the 5.5 backup with utf8_general50_ci collation. Bug fixed #1533722 (Fungo Wang).
Percona XtraBackup would crash if --throttle was used while preparing backups. Fixed by making this option available only during the backup process. Bug fixed #1691093.
Percona XtraBackup could get stuck if backups are taken with --safe-slave-backup option, while there were long-running queries. Bug fixed #1717158.
