Notable Changes

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.See the commit for details.

• The JSON data type (an alias for LONGTEXT) was introduced.

• InnoDB updated to 5.7.18

• TokuDB updated to 5.6.36-82.0

• mariadb-backup beta now included for Red Hat, CentOS, and Fedora packages. See MDEV-13311 for an important note about restoring with this version.

• MDEV-13125: Core dumps can now be enabled dynamically
