[MariaDB 10.2](/docs/release-notes/community-server/old-releases/10.2/what-is-mariadb-102.md) is the current stable series of MariaDB. It is an evolution of [MariaDB 10.1](/docs/release-notes/community-server/old-releases/10.1/changes-improvements-in-mariadb-10-1.md) with several entirely new features not found anywhere else and with backported and reimplemented features from MySQL 5.6 and 5.7.

[MariaDB 10.2.7](/docs/release-notes/community-server/old-releases/10.2/10.2.7.md) is a [***Stable (GA)***](/docs/release-notes/community-server/about/release-criteria.md) release.

**For an overview of** [**MariaDB 10.2**](/docs/release-notes/community-server/old-releases/10.2/what-is-mariadb-102.md) **see the**[**What is MariaDB 10.2?**](/docs/release-notes/community-server/old-releases/10.2/what-is-mariadb-102.md) **page.**

## Notable Changes

This is the second stable release in the [MariaDB 10.2](/docs/release-notes/community-server/old-releases/10.2/what-is-mariadb-102.md) series.

A file format compatibility bug that was introduced in [MariaDB 10.2.2](/docs/release-notes/community-server/old-releases/10.2/10.2.2.md) was fixed in this version of MariaDB. Creating tables with the attribute [page\_compressed=yes](/docs/server/server-usage/storage-engines/innodb/innodb-page-compression.md) created InnoDB internal data dictionary records that are incompatible with [MariaDB 10.1](/docs/release-notes/community-server/old-releases/10.1/changes-improvements-in-mariadb-10-1.md). [MariaDB 10.2.7](/docs/release-notes/community-server/old-releases/10.2/10.2.7.md) and later will write the dictionary records in a format that is compatible with [MariaDB 10.1](/docs/release-notes/community-server/old-releases/10.1/changes-improvements-in-mariadb-10-1.md) and will also support the malformed metadata from affected 10.2 versions.**This may prevent a downgrade to earlier** [**MariaDB 10.2**](/docs/release-notes/community-server/old-releases/10.2/what-is-mariadb-102.md) **versions.**[See the commit for details.](https://github.com/MariaDB/server/commit/72378a25830184f91005be7e80cfb28381c79f23)

* The [JSON data type](/docs/server/reference/data-types/string-data-types/json.md) (an alias for LONGTEXT) was introduced.
* [InnoDB](/docs/server/server-usage/storage-engines/innodb/innodb-versions.md) updated to 5.7.18
* TokuDB updated to 5.6.36-82.0
* [mariadb-backup](https://mariadb.com/docs/server/server-usage/backup-and-restore/mariadb-backup) beta now included for Red Hat, CentOS, and Fedora packages. See [MDEV-13311](https://jira.mariadb.org/browse/MDEV-13311) for an important note about restoring with this version.
* [MDEV-13125](https://jira.mariadb.org/browse/MDEV-13125): Core dumps can now be enabled dynamically
* [MDEV-13132](https://jira.mariadb.org/browse/MDEV-13132): Literals in the `COLUMN_DEFAULT` column in the [Information Schema COLUMNS](/docs/server/reference/system-tables/information-schema/information-schema-tables/information-schema-columns-table.md) table are now quoted to distinguish them from expressions.
* New variables:
  * [tmp\_disk\_table\_size](/docs/server/server-management/variables-and-modes/server-system-variables.md#tmp_disk_table_size)
  * [tmp\_memory\_table\_size](/docs/server/server-management/variables-and-modes/server-system-variables.md#tmp_memory_table_size)
* As per the [MariaDB Deprecation Policy](/docs/release-notes/community-server/about/platform-deprecation-policy.md), this will be the last release of [MariaDB 10.2](/docs/release-notes/community-server/old-releases/10.2/what-is-mariadb-102.md) for Ubuntu 16.10 "Yakkety"
