WordPress 3.0 Released

Last Updated on by

It was just announced today that WordPress 3.0 has been released and you can get it here. This is considered a pretty big release with many new features and bug fixes, I’ll list some notable ones below:

  • A merge of WordPress MU and WordPress, making it possible to run multiple sites from one installation.
  • New features for theme developers including new APIs to have custom backgrounds, headers, menus, and more.
  • New custom post type and taxonomy features for posting new and different kinds of content (besides posts, pages, etc.).
  • A new default theme called Twenty Ten, which shows off all this new functionality. Say bye bye to Kubrick!

Watch the video below for more information:

If you’re upgrading, remember to backup your site. Also remember your themes probably won’t break but if they do, you can at least revert back to your backup and figure out what the problem is.

Have you upgraded to WordPress 3.0? I’d be interested in hearing your experience in the comments.

    We accidentally upgraded to WordPress 3.0 and would love some advice about reverting back to an earlier version. Our site uses a few plugins and one in particular, Events Calendar doesn’t seem to work wtih 3.0. Any advice?

      Carol, unless you took a backup there really isn’t a straightforward method that I’m aware of for reverting back.

    Unfortunately we did not anticipate this upgrade. Right now I am trying to install a 2.9.2 version of WordPress and rebuild the site using the files I have backed up. Fortunately we haven’t had much added to the site so if I have to go back and start using the protosite version, we’ll be okay. What a pain though.
