- 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 MediaZilla (our version of BugZilla).
MediaWiki 1.23.5 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.

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.

- The future version 1.25 (used as 1.25wmf on MediaWiki projects)

- The stable version 1.23 (replaced by 1.24 in November 2014)

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.
