Notes

Percona XtraBackup (as of 2.4) will not work with MariaDB 10.2 (and MariaDB 10.1) compression. However, MariaDB's fork, mariadb-backup, will work with compression. A beta version of mariadb-backup was included in MariaDB 10.2.7 and declared stable in MariaDB 10.2.10.

A file format compatibility bug that was introduced in MariaDB 10.2.2 was present in this release. Creating tables with the attribute page_compressed=yes created InnoDB internal data dictionary records that are incompatible with MariaDB 10.1. MariaDB 10.2.7 and later will write the dictionary records in a format that is compatible with MariaDB 10.1 and will also support the malformed metadata from affected 10.2 versions.This bug may prevent a downgrade from later MariaDB 10.2 versions to MariaDB 10.2.6.See the commit for details.
