Hot off the metaphorical press is the latest WordPress release – WordPress 2.2.1. This is a security update for WordPress 2.2, and upgrading is not regarded as optional. Do it now, while your site is your own.
If you’re still using WordPress 2.0.something, you can continue to do so safely. The latest security issue does not affect you, and updates for your version will be released as they are needed.
If you are using WordPress 2.1.something, stop reading this and upgrade your site now.
As usual, I upgraded using Bryan Layman’s remarkably painless latest version of WPEasyUpdate. If you have shell access, this has to be the best way to get your WordPress up to the latest release. It even backs up your files and database before it starts, which is good for the paranoid amongst us.
Just for laughs, I didn’t follow my usual advice of disabling all my plugins this time. So far, things seem to be working.
