Dougal Campbell's geek ramblings

WordPress 2.2.1 is now available. Most of the changes are minor bug fixes, however there are some security fixes as well. We can’t stress enough how important it is to upgrade your sites and keep them current so that you aren’t open to attacks. Many people see these “minor” version updates and assume that they don’t need to install them. Mainly it seems to be folks who worry about an upgrade breaking their theme or their plugins. But if the themes and plugins are written properly, this won’t normally be a problem. So, if you are running any version of WordPress older than 2.2.1, go download the new version now.

If you’re curious about what’s changed since 2.2.0, read the list of changes on Trac. Or, you can view the source code changes for all the changed files.
