Yesterday, the guys from WordPress.org released the next version of the popular CMS, WordPress. The 2.6.5 version doesn’t bring any features on the table, it’s more of a security update. If you want to see the changelog from the 2.6.3 version of WordPress to the current one, please visit the WordPress Trac.
The biggest security fix in this build was a discovered XSS exploit that was affecting virtual servers running under Apache 2.x.
Being a security update, we strongly recommend you to update your WordPress install.
