MediaWiki is a Wiki software package licensed under the GNU General Public License. It is a feature-rich wiki implementation written primarily for Wikipedia and other Wikimedia Foundation projects, but also used by many other wikis. It is also available to anyone who wishes to use it for their own personal website.

It is written in PHP with the texvc math renderer in OCaml and uses an underlying MySQL relational database management system. Its logo symbolizes how its markup language uses double brackets ("[[","]]") to link articles together. MediaWiki is capable of interfacing with other, optional programs to improve performance and capabilities. Support for memcached, the Squid cache system, and TeX math rendering are all available in the current version. An extension and hook system allows users to add their own features and program interfaces.

History

MediaWiki was originally written for Wikipedia by the German University of Cologne student and developer Magnus Manske. The site previously used Perl-based UseModWiki (nicknamed "Phase I" by the Wikipedia community), then switched to PHP with a new version ("Phase II") on January 25, 2002. The day is known within the Wikipedia community as "Magnus Manske Day."

In mid-2002, the software was further rewritten and improved ("Phase III") by Lee Daniel Crocker, and has been incrementally developed from this code base since. Starting in mid-2003, the previously unnamed program was named "MediaWiki" and regular public releases began to be made with non-Wikipedia users in mind.

The wiki engine was released under the name MediaWiki for the first time on August 29, 2003. The release name of that particular release was MediaWiki-stable 20030829.

The name was chosen by Wikipedian Daniel Mayer as a play on 'Wikimedia', Wikipedia's parent organization which was being formally established around this time. The name is, however, occasionally criticised for its similarity to "Wikimedia", which leads to confusion among people new to the project.

Version 1.4

MediaWiki 1.4 was released on March 20, 2005. Brion Vibber became the lead developer. For version 1.4, the code was cleaned up so that certain tasks could be performed in half the time. One new feature was the user's ability to change the interface language, making other language projects more accessible.

Mediawiki 1.4 used gzip to compress stored text, which resulted in compression to about 15% of the original disk storage used. Further storage saving was achieved by adding support for "block-compressed revisions", which combined multiple revisions before compressing.

Version 1.5

MediaWiki 1.5 was released on October 5, 2005. It continues the architectural changes started in version 1.4. Its most notable change is a substantially redesigned database schema, which finally completely decouples text storage from article revision tracking. This is expected to increase the speed of various operations like page moves and generating page history listings, as well as allowing unchanging bulk data to be stored outside the database. This new version also supports the use of the SVG file format for vector images.

Version 1.6

MediaWiki 1.6 is the current stable version, released April 5, 2006. See release notes on the official homepage. It is currently in use on Wikimedia Foundation's sites, including the English Wikipedia.
