The PHP group has released an update to the recent PHP 5.1.3 version of the popular web development language, correcting a critical bug that caused issues with the values in the $_POST superglobal - version 5.1.4.

As Chris Shiflett mentions here, as of this posting, there's no official announcemnt, but you can grab the copy from a mirror site via this link.

For more information on the bug and what was fixed, keep an eye on the downloads page on PHP.net for its posting.
