MediaWiki 1.5rc1 is a preview release of the new 1.5 release series. Numerous bug fixes since last beta, plus a security fix; see change log in the release notes for full details.

A flaw in the interaction between extensions and HTML attribute sanitization was discovered which could allow unauthorized use of offsite resources in style sheets, and possible exploitation of a JavaScript injection feature on Microsoft Internet Explorer.

This version expands the returned text and properly checks it before output.

MediaWiki 1.4.8 is a bug fix and security maintenance release. It fixes the above bug, plus an update to skins/MonoBook.php ensures that sites using the default MonoBook skin will display correctly in the Internet Explorer 7 beta. (1.3 and 1.5 are not affected by this display problem.)

MediaWiki 1.3.14 is a security maintenance release.

The 1.3.x series is no longer maintained except for security fixes; new users and those seeking bug fixes should upgrade to 1.4.8 or 1.5rc1. Existing 1.3.x installations not willing to upgrade to the current stable relase should apply the change manually; details are in the release notes.

If you are actively using extensions to generate HTML attribute values, upgrade to 1.4 or 1.5 for a full fix; 1.3.14 simply disables any attempt to use such.
