WordPress 2.7.1 has been released this week. Even though it is a maintenance release, I strongly suggest you to upgrade to it. If you are already using WordPress 2.7, you can take advantage of the automatic built-in upgrade of WordPress. If you are not, then you should immediately do that because your blog is becoming more vulnerable to some serious security threats day by day. With this addition 68 WordPress bugs were fixed. You can check the  fixes and feature improvements at Lorelle On WordPress.
