Current versions:
1.4.7
1.5 beta4
MediaWiki is a free Wiki software package licensed under the GNU General Public License. It is used to run Wikipedia and other Wikimedia Foundation projects, as well as many other wikis. In case you don't already know, a wiki is a publicly editable website which allows its visitors to collaborate by editing its pages.
What is a Wiki?
To overcome without danger, one triumphs without glory. (Pierre Corneille)
Welcome to visitors who are new to the Wiki concept
and probably came here because they clicked on a Powered by MediaWiki icon.
You are entering a world of respect and trust.
Yes : you can modify this page and you can even (temporarily) publish dummy sentences,
and you can even (temporarily) completely destroy the page.
You don't need to be a hacker to do this.
We suggest you rather exercise yourself within another page (just click here to reach such a page)
to avoid other visitors needing to clean up this main page after you.
If you want to share your knowledge about MediaWiki, you may edit this page.
If you have a question or a suggestion, do not edit this page, but, instead, use the related discussion page.
I prefer the wicked rather than the foolish. The wicked sometimes rest. (Alexandre Dumas, père 1802-1870)
How does MediaWiki work?
MediaWiki uses PHP to process and display data stored in its MySQL database. Pages use MediaWiki's wikitext format, so that users without knowledge of XHTML or CSS can edit them easily. When a user submits an edit to a page, MediaWiki writes it to the database, but without deleting the previous versions of the page, thus allowing easy reverts in case of vandalism or spamming. MediaWiki can manage image and multimedia files, too, which are stored in the filesystem. For large wikis with lots of users, MediaWiki supports caching and can be easily coupled with Squid.
To install MediaWiki, you will need any operating system (GNU/Linux is suggested), any web server (apache2 is suggested), PHP >= 4.3 (PHP 4.3.11 is suggested) and MySQL >= 3.23 (MySQL 4.0.23 is suggested). You do not need a specific software to manage MySQL but such a tool may help you for backups and other tasks (phpMyAdmin 2.6.1 is suggested). MediaWiki ships with an installation utility which will enable you to install it using your Web browser. If you do not operate your own server and have only access to one database, mind that MediaWiki is able to share its database with other applications. You don't need to know SQL, HTML, XHTML or CSS. A basic knowledge of PHP is required if you need to modify the configuration files.

Important Release Notes
Stable releases series 1.4.x
1.4.7 released 2005-07-16: Stable series bugfix release
[[[:Template:Download]] mediawiki-1.4.7.tar.gz]
- MediaWiki 1.4.7 is a bug fix release. Those affected by the following problems in 1.4.6 should upgrade:
- Watchlist breakage on MySQL 3.23.x and with table prefix enabled
- Possible breakage in watchlist, some image resizing modes on PHP 4.1.2
- 1.4.6 included a fix for a cross-site scripting vulnerability, so anyone running older 1.4 releases is very strongly encouraged to upgrade as well.
- Note to upgraders: current versions of MediaWiki are known to produce a large number of notice-level warnings under the newly released PHP 4.4.0. These appear however to be harmless; if you encounter them add this to your LocalSettings.php to suppress the notices:
error_reporting( E_ALL & ~E_NOTICE );
- PHP 5.1.0beta3 is known to be incompatible at this time.
- Changes since last release: (full release notes)
- (MediaZilla:2755, MediaZilla:2747) MySQL 3.23.x and table prefix compatibility fix: restore old watchlist code
- PHP 4.1.2 compatibility fix: define floatval() equivalent if missing
1.4.6 released 2005-07-07: Stable series security and bugfix release. For details of this and all earlier releases, please see the old main page at wikipedia.sourceforge.net.
