WC 2.4 beta 4 was tagged yesterday evening and is ready to test. Beta 4 should be the final beta before a release candidate is tagged later this week. If you’re an extension of theme author make sure you test as soon as possible.
If you want to read more about whats changed in 2.4, see this post. To find out how you can beta test, we wrote a short post with a plugin based solution.
Thanks to everyone who gets involved.
