WordPress has a new security upgrade with 2.8.5. The major fixes are a fix for the Trackback Denial-of-Service attack that is currently being seen. Removal of areas within the code where php code in variables was evaluated. Switched the file upload functionality to be whitelisted for all users including Admins. And, Retiring of the two importers of Tag data from old plugins.

It’s recommended that the upgrade be performed. I just upgraded a couple of my sites with no issues (so far). Read more about the upgrade here http://wordpress.org/development/2009/10/wordpress-2-8-5-hardening-release. You can either upgrade right in your blog administration if you’ve manually installed WordPress or you can just download the new version at http://wordpress.org.

You can also hire me to upgrade your blog for you. I offer WordPress Installation http://sweetboutiquedesign.com/item_26/WordPress-Installation.htm.
