MediaWiki 1.25
THIS IS NOT A RELEASE YET

MediaWiki 1.25 is an alpha-quality branch and is not recommended for use in production.

Languages updated in 1.25
MediaWiki supports over 350 languages. Many localisations are updated regularly. Below only new and removed languages are listed, as well as changes to languages because of Bugzilla reports.

Other changes in 1.25

 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for migration guide for creators and users of custom skins that relied on it.

Compatibility
MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for HHVM 3.3.0.

MySQL 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 5.0.2 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
1.25 has several database changes since 1.24, 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).

If upgrading from before 1.11, and you are using a wiki as a commons repository, make sure that it is updated as well. Otherwise, errors may arise due to database schema changes.

If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data.

If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed with MediaWiki 1.21.

Don't forget to always back up your database before upgrading!

See the file UPGRADE for more detailed upgrade instructions.
