MediaWiki 1.19

This is a MediaWiki version which was deployed in February 2012, had betas released in March 2012, and will have a release candidate and hopefully the final release out in April 2012.

What's new?
The comprehensive list of what's new is in the release notes. But here's an overview:

Easier reading, editing, and maintenance

 * Disable the partial HTML and MathML rendering options for Math, and render as PNG by default (see RFC and )
 * MathML mode was so incomplete most people thought it simply didn't work.
 * Searching blocked usernames in block log is now clearer.
 * The default user signature now contains a talk link in addition to the user link.
 * Better timezone recognition in user preferences.

Internationalization

 * More gender support (for instance in user lists).
 * Added language: Canadian English.
 * Language converter improved, e.g. it now works depending on the page content language.
 * Time and number-formatting magic words also now depend on the page content language.
 * Bidirectional support further improved after 1.18.

Improvements for extensions developers

 * Extensions can now participate in the extraction of titles from URL paths.

Heads-up for MediaWiki administrators

 * Bumped MySQL version requirement to 5.0.2.
 * The command-line installer supports various RDBMSes better.
 * New skins/common/*.css files usable by skins instead of having to copy piles of generic styles from MonoBook or Vector's css.

And more!

 * The interwiki links table can now be accessed also when the interwiki cache is used (used in the API and the Interwiki extension).
