WordPress 3.0.4 has been released. This is considered a critical upgrade, as it addresses an important security vulnerability.
From the WordPress.org Blog:
Version 3.0.4 of WordPress, available immediately through the update page in your dashboard or for download here, is a very important update to apply to your sites as soon as possible because it fixes a core security bug in our HTML sanitation library, called KSES. I would rate this release as “critical.”
I realize an update during the holidays is no fun, but this one is worth putting down the eggnog for. In the spirit of the holidays, consider helping your friends as well.
All WordPress users should upgrade immediately. The process is quick and painless; just click the upgrade link in the WordPress dashboard.
