MediaWiki is wiki software, released under the GPL, that is used by Wikimedia projects and others. It is an implementation of a wiki, a content pool that anyone can freely edit. It is developed using Phabricator, our instance of Phacility phabricator.

MediaWiki 1.29.2 is the latest stable version, and is recommended for third-party users. Those running their own servers should upgrade for security reasons. Special:Version shows what version a site is running. You can play around in the local Sandbox to see this version in action.

MediaWiki 1.29.2 is available for download from, a site that is also responsible for the documentation of the software. MediaWiki 1.31.0-wmf.17 (d8c8c31) is currently running on all Wikimedia sites. Third-party users should probably not run the alpha/beta versions of MediaWiki on publicly accessible servers at this time.



Technical developers section




At the moment there is a current version maintained for at least one year after its release date, and the last legacy version still getting security fixes. Older versions are considered as insecure. As of April 2016 there are four supported versions:

  1. The future version 1.27 (used as 1.27wmf on MediaWiki projects)
  2. The stable version 1.26 supported until November 2016
  3. The legacy version 1.25 supported until June 2016
  4. The old LTS version 1.23 supported until May 2017
  5. The new LTS version will be 1.27 (2016 until 2019)

Database dump

For downloadable dumps of Wikipedia's article database, see Wikipedia:Database download. For a description of the database format and fields, see database layout.

To create your own dump of a local MediaWiki site, you can use the dumpBackup.php script found in the maintenance directory of your MediaWiki installation tree.

An example invocation to a full backup might look like:

 php maintenance/dumpBackup.php --full > full.xml

Command line options for dumpBackup.php are explained by running it with no parameters, i.e.

 php maintenance/dumpBackup.php

However, there are some extra undocumented options in its source code.
