From Wordpress.org:
Version 2.5.1 of WordPress is now available. It includes a number of bug fixes, performance enhancements, and one very important security fix. We recommend everyone update immediately, particularly if your blog has open registration. The vulnerability is not public but it will be shortly.
In addition to the security fix, 2.5.1 contains many bug fixes. If you are interested only in the security fixes, you can download these corrected copies of wp-includes/pluggable.php, wp-admin/includes/media.php, and wp-admin/media.php. Replace your existing copies of these files with these new copies.
If you download the entire 2.5.1 release, you will be getting over 70 other fixes. 2.5.1 focuses on fixing the most annoying bugs and improving performance.
I’m downloading now and will be updating here shortly… I suggest you do, too!
UPDATE – WordPress 2.51 is installed and live… so far, no issues! Whoo!
