Quick – how can there be two current versions of WordPress, 2.8.5 AND 2.8.5.2?

The answer – two quick releases, one for ‘regular’ WordPress, and the latter for WP MU.

The first, with several fixes, primarily focuses on security for trackbacks, which can be used for a denial of service attack. You can get it via their regular site.

For WP MU, the 2.8.5.2 version is a quick patchup to account for small bugs that crept into the 2.8.5 version – and that’s found on their MU site.

So while 2.9 is on its way, you have a little something new to bide the time with!
