[Changelog](https://mariadb.com/docs/release-notes/community-server/changelogs/changelogs-mariadb-52-series/mariadb-520-changelog) | [MariaDB 5.2](https://mariadb.com/docs/release-notes/community-server/old-releases/5.2/changes-improvements-in-mariadb-5-2) contains features that didn't have time to go into [MariaDB\ 5.1](https://mariadb.com/docs/release-notes/community-server/old-releases/5.1/changes-improvements-in-mariadb-5-1). For all practical purposes it's a drop in replacement for [MariaDB 5.1](https://mariadb.com/docs/release-notes/community-server/old-releases/5.1/changes-improvements-in-mariadb-5-1) (and thus MySQL 5.1). [MariaDB 5.2](https://mariadb.com/docs/release-notes/community-server/old-releases/5.2/changes-improvements-in-mariadb-5-2) is based on [MariaDB 5.1](https://mariadb.com/docs/release-notes/community-server/old-releases/5.1/changes-improvements-in-mariadb-5-1) and thus MySQL 5.1. The new features in 5.2 are quite isolated and as most have been in use by\ members in the MySQL community for a long time. Current versions of [MariaDB 5.2](https://mariadb.com/docs/release-notes/community-server/old-releases/5.2/changes-improvements-in-mariadb-5-2) are [stable](https://mariadb.com/docs/release-notes/community-server/about/release-criteria) and can be downloaded from [downloads.askmonty.org](https://downloads.askmonty.org). ### New storage engines * [OQGRAPH](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/oqgraph-storage-engine) * Allows you to handle hierarchies (tree structures) and complex graphs (nodes\ having many connections in several directions) * [SphinxSE](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/sphinx-storage-engine): Text search within MariaDB. * A built-in Sphinx client which allows MariaDB to talk to searchd, run search\ queries, and obtain search results. ### New features * [Virtual columns](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-statements/data-definition/create/generated-columns) * Columns that are an expression and are calculated on retrieval. * [Extended User Statistics](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/optimization-and-tuning/query-optimizations/statistics-for-optimizing-queries/user-statistics) * Client, User, Index and Table statistics. * [Segmented MyISAM key cache](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/optimization-and-tuning/system-variables/segmented-key-cache) * The key cache's global mutex is split into several mutex which gives a\ notable speed improvement under multi user load. We have registered up to [250% more performance](https://mariadb.com/docs/release-notes/community-server/old-releases/5.2/broken-reference) thanks to this. * [Pluggable Authentication](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/plugins/authentication-plugins/pluggable-authentication-overview) * Authentication is done via an extensible plugin, which makes it easy to add\ any kind of authentication to MariaDB. * [Storage-engine-specific CREATE TABLE](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/product-development/plugin-development/storage-engines-storage-engine-development/engine-defined-new-tablefieldindex-attributes) * Allows one to specify additional attributes per field, index or table to the\ storage engine. * [Enhancements to INFORMATION SCHEMA.PLUGINS table](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/system-tables/information-schema/information-schema-tables/plugins-table-information-schema) * We expose more information about the plugins, like maturity levels. * [Group commit](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/aria/aria-group-commit) for the [Aria](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/aria) engine. * Speeds up multi user inserts. ### Other things We have also done several smaller speed improvements, bug fixes and code\ cleanups. ### Security Vulnerabilities Fixed in [MariaDB 5.2](https://mariadb.com/docs/release-notes/community-server/old-releases/5.2/changes-improvements-in-mariadb-5-2) For a complete list of security vulnerabilities (CVEs) fixed across all\ versions of MariaDB, see the [Security Vulnerabilities Fixed in MariaDB](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/security/cve)\ page. * [CVE-2013-1531](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1531): [MariaDB
