== MediaWiki 1.31 == THIS IS NOT A RELEASE YET MediaWiki 1.31 is an alpha-quality branch and is not recommended for use in production. === Configuration changes in 1.31 === * $wgEnableAPI and $wgEnableWriteAPI are now deprecated and will be removed in a future version. The API is now considered to be stable, secure and essential. * $wgUsejQueryThree was removed, as it is now the default. This was documented as a temporary variable during the migration period, deprecated since 1.29. * $wgLogoHD has been updated to support svg images and uses $wgLogo where possible for fallback images such as png. * (T44246) $wgFilterLogTypes will no longer ignore 'patrol' when user does not have the right to mark things patrolled. * Wikis that contain imported revisions or CentralAuth global blocks should run maintenance/cleanupUsersWithNoId.php. * $wgResourceLoaderMinifierStatementsOnOwnLine and $wgResourceLoaderMinifierMaxLineLength were removed (deprecated since 1.27). * (T180921) $wgReferrerPolicy now supports having fallbacks for browsers that are not using the latest version of the Referrer Policy specification. * $wgFragmentMode is now set to [ 'legacy', 'html5' ] by default.

Although HHVM 3.18.5 or later is supported, it is generally advised to use PHP 5.5.9 or later for long term support. MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used, but support for them is somewhat less mature. There is experimental support for Oracle and Microsoft SQL Server. The supported versions are: * MySQL 5.0.3 or later * PostgreSQL 8.3 or later * SQLite 3.3.7 or later * Oracle 9.0.1 or later * Microsoft SQL Server 2005 (9.00.1399) == Upgrading == 1.31 has several database changes since 1.30, and will not work without schema updates. Note that due to changes to some very large tables like the revision table, the schema update may take quite long (minutes on a medium sized site, many hours on a large site). Don't forget to always back up your database before upgrading! See the file UPGRADE for more detailed upgrade instructions, including important information when upgrading from versions prior to 1.11.
