The latest and greatest version of WordPress (Version 2.8.5) has been released. We cannot express enough how important keeping up with these changes are. Please do not ignore site maintenance.
You may be thinking that these changes reflect how vulnerable WordPress is, in reality it is just the opposite. All sites have a measure of risk regarding security – it is never a matter of “if” you will have a security breach, but rather “when” your will be breached. Because WordPress uses open source and their experts are continually making improvements, risks are more likely to be discovered prior to an actual security breach.

Below are some excerpts form their release notice:
As you know over the past couple of months we have been working on the new features for WordPress 2.9. We have also been working on trying to make WordPress as secure as possible and during this process we have identified a number of security hardening changes that we thought were worth back-porting to the 2.8 branch so as to get these improvements out there and make all your sites as secure as possible.
We would recommend that all sites are upgraded to this new version of WordPress to ensure that you have the best available protection.
