To the bloggers out there using WordPress as their platform of choice its time to upgrade. This release addresses a couple of security issues.
From WordPress:
WordPress 2.6.5 is immediately available and fixes one security problem and three bugs. We recommend everyone upgrade to this release.
The security issue is an XSS exploit discovered by Jeremias Reith that fortunately only affects IP-based virtual servers running on Apache 2.x. If you are interested only in the security fix, copy wp-includes/feed.php and wp-includes/version.php from the 2.6.5 release package.
Please note that the jump from 2.6.3 to revision 2.6.5 is intentional. There is not, nor will ever be, a version of WordPress at 2.6.4 due to a fake code release.
Right, on yer bike.
