== MediaWiki 1.29 == THIS IS NOT A RELEASE YET MediaWiki 1.29 is an alpha-quality branch and is not recommended for use in production. === Configuration changes in 1.29 === * Default cookie expiration time has been reduced to 30 days. Login cookie expiration time is kept at 180 days. * A new configuration variable has been added: $wgCookieSetOnAutoblock. This determines whether to set a cookie when a user is autoblocked. Doing so means that a blocked user, even after logging out and moving to a new IP address, will still be blocked. === New features in 1.29 === * (T5233) A cookie can now be set when a user is autoblocked, to track that user if they move to a new IP address. This is disabled by default. === External library changes in 1.29 === ==== Upgraded external libraries ==== ==== New external libraries ==== ==== Removed and replaced external libraries ==== === Bug fixes in 1.29 === === Action API changes in 1.29 === * Submitting sensitive authentication request parameters to action=clientlogin, action=createaccount, action=linkaccount, and action=changeauthenticationdata in the query string is now an error. They should be submitted in the POST body instead. === Action API internal changes in 1.29 === === Languages updated in 1.29 === 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 Phabricator reports. === Other changes in 1.29 === * Database::getSearchEngine() (deprecated in 1.28) was removed. Use SearchEngineFactory::getSearchEngineClass() instead. == Compatibility == MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for HHVM 3.6.5 or later. 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 5.0.3 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 == 1.29 has several database changes since 1.28, 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. For notes on 1.28.x and older releases, see HISTORY. == Online documentation == Documentation for both end-users and site administrators is available on MediaWiki.org, and is covered under the GNU Free Documentation License (except for pages that explicitly state that their contents are in the public domain): https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation == Mailing list == A mailing list is available for MediaWiki user support and discussion: https://lists.wikimedia.org/mailman/listinfo/mediawiki-l A low-traffic announcements-only list is also available: https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce It's highly recommended that you sign up for one of these lists if you're going to run a public MediaWiki, so you can be notified of security fixes. == IRC help == There's usually someone online in #mediawiki on irc.freenode.net.
