MediaWiki 1.4beta5 released (SECURITY)

MediaWiki 1.4beta5 is a security and bug fix release for the 1.4 beta series. Previous MediaWiki 1.4 beta releases include an input validation error which could lead to execution of arbitrary PHP code on the server.

All users of 1.4 beta releases are strongly urged to upgrade to 1.4beta5 immediately. The 1.3.x stable release series is not affected by this problem.

Beta 5 additionally fixes a number of non-security-related bugs, and requires one minor database change. If upgrading from a previous beta, see the file UPGRADE in the release archive for instructions.

Due to a temporary problem with SourceForge's file release system, this release is currently hosted on Wikimedia's servers instead of the usual location.
