MediaWiki is wiki software, released under the GPL, that is used by Wikimedia projects as well as other websites. 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 1.39.2 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 1.39.2 is available for download from MediaWiki.org, a site that is also responsible for the documentation of the software. MediaWiki 1.41.0-wmf.1 (4de0415) 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.

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.
