- Note: the name "MediaWiki" is often confused with several other, similar, names; please see the glossary for an explanation of these.
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's Phabricator.
MediaWiki 1.34.0 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 1.34.0 is available for download from MediaWiki.org, a site that is also responsible for the documentation of the software. MediaWiki 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.

At the moment there is a stable version maintained for at least one year after its release date, and the last legacy versions still getting security fixes. Older versions are considered as insecure. As of February 2020 there were three supported versions, with a new LTS 1.35 planned for May 2020:
- The future version 1.35 (REL1_35 branch in October 2019)
- The stable version 1.34 supported until November 2020
- The legacy version 1.33 supported until June 2020
- The old LTS version 1.35 supported until June 2021
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.
However, there are some extra undocumented options in its source code.
