Last piece of news for tonight, this time from the Release Team:
"We are pleased to announce the release of Pre-RC1 build 5536.16385! This build represents significant progress incorporating your Beta 2 and 5472 feedback.
We have made a lot of progress since Beta 2 and 5472, and we think you will notice the quality improvements that we’ve been seeing in the daily builds."
This interim build is not widely distributed (you'll have to wait for RC1) but does serve to underscore the progress the Dev and Test teams have made since Beta 2, while also confirming that we're still on track for the release of RC1 in the near future.
