New features
Percona XtraBackup has been rebased on MySQL 5.7.13.
Bugs Fixed
Percona XtraBackup reported the difference in the actual size of the system tablespace and the size which was stored in the tablespace header. This check is now skipped for tablespaces with autoextend support. Bug fixed #1550322.

Because Percona Server 5.5 and MySQL 5.6 store the LSN offset for large log files at different places inside the redo log header, Percona XtraBackup was trying to guess which offset is better to use by trying to read from each one and compare the log block numbers and assert lsn_chosen == 1 when both LSNs looked correct, but they were different. Fixed by improving the server detection. Bug fixed #1568009.

Percona XtraBackup didn’t correctly detect when tables were both compressed and encrypted. Bug fixed #1582130.

Percona XtraBackup would crash if the keyring file was empty. Bug fixed #1590351.

Backup couldn’t be prepared when the size in cache didn’t match the physical size. Bug fixed #1604299.

Free Software Foundation address in copyright notices was outdated. Bug fixed #1222777.

Backup process would fail if the datadir specified on the command-line was not the same as one that is reported by the server. Percona XtraBackup now allows the datadir from my.cnf override the one from SHOW VARIABLES. xtrabackup will print a warning that they don’t match, but continue. Bug fixed #1526467.

With upstream change of maximum page size from 16K to 64K, the size of incremental buffer became 1G. Which increased the requirement to 1G of RAM in order to prepare the backup. While in fact there is no need to allocate such a large buffer for smaller pages. Bug fixed #1582456.

Backup process would fail on MariaDB Galera cluster operating in GTID mode if binary logs were in non-standard directory. Bug fixed #1517629.
Other bugs fixed: #1583717, #1583954, and #1599397.
