Our process for moving builds from one status to another is explained in the first section of this wiki article:
UpdatesAt the moment, we're serving build 95 on the download page and 142 on the MC15 board. That's a lot of builds with lots of changes. Normally we would have changed from 95 to something newer before this, but doing that requires a build that has something more to offer AND is stable. You might expect that to be a lot easier than it is.
I'm guessing that 142 will be moved to the download page this week.
