Release date: 12 Jul 2017
MariaDB 10.2 is the current stable series of MariaDB. It is an evolution of MariaDB 10.1 with several entirely new features not found anywhere else and with backported and reimplemented features from MySQL 5.6 and 5.7.
This is the second stable release in the MariaDB 10.2 series.
A file format compatibility bug that was introduced in MariaDB 10.2.2 was fixed in this version of MariaDB.
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 may prevent a downgrade to earlier MariaDB 10.2 versions.
