June 24, 2004
The following MediaWiki features are currently disabled in the English Wikipedia (and other large Wikimedia wikis) for performance reasons:
- Individual page access counters (for the foreseeable future)
- Most wanted, popular pages (temporary). As a temporary replacement the following static lists have been produced from a database dump: Most referenced pages, Most wanted pages
Recently, search, orphaned, short, and long pages were reenabled.
Wikipedia and its sister Wikimedia projects run on the same GPL-ed free software, called MediaWiki or Software Phase III (see m:MediaWiki). It was switched from UseModWiki software ("Phase I") to new software, written especially for Wikipedia using the PHP programming language, on January 25, 2002 ("Phase II"); in July 2002 it was replaced by what is now called MediaWiki.
Magnus Manske was the original author of the software, which is written in PHP and uses an underlying MySQL relational database. The software is released under the GNU General Public License. Other programmers are strongly urged to get involved.
MediaWiki was made for wikipedia and later for its sister sites and then released as the open-source MediaWiki
