It is not just regular WordPress that is closing in on version 2.8, the multiuser variant, called WordPress MU, is being updated as well. Donncha O Caoimh announced the changes, so far just available from the trunk, but there nonetheless.
I merged WP 2.8 beta1 and I’m fixing bugs. Please install and try it out on a test server! The get_option() and related code is using the same code as WordPress.org which is one of the main reasons I went digging into the object cache. It leans a lot more on the cache than previously. Please test!
Remember, this is not a beta and is not intended for public use, but if you like to see things break then this is your thing. Just put it on a test server. WordPress MU is what powers sites like WordPress.com, among other things. It is for blog hosts (and networks) primarily, not for users.
