Although there doesn't seem to be any official announcement as of yet, a new build of WLMd is available. Sign up at ideas.live.com if you haven't tried out the public beta, or if you're signed up you can download it here.
And while it's been out for a few days, this might be a good time to mention that you can provide feedback or submit bugs on WLMd through Microsoft Connect. This is a new feature for public betas, previously access to Connect was limited to "managed beta" testers.
