WordPress 2.1.3 and 2.0.10 has just been released few hours ago. After getting some security issues and hack attempts last month, the team had been working hard on it just to prevent the same thing happen again.
These releases include fixes for several publicly known minor XSS issues, one major XML-RPC issue, and a proactive full sweep of the WordPress codebase to protect against future problems.
The fact is, how many users will update their WordPress version whenever there is a new version released? Will you? To be honest, I don’t 😆 . The best solution for me is to upgrade after a few versions released.
