For the 13.04 release, Ubuntu made a change to its procedure whereby source-only uploads to the development release (e.g. raring) actually go to e.g. raring-proposed first. The builds are attempted and only if they succeed, pass their autopkgtests, *and* don't make the archive less installable than before the new upload, are the packages copied over to the release, e.g. raring. In practice, I think this works very well. No users are exposed to broken packages, or new versions that introduce more installation problems, and developers can upload source-only. Mostly gone are the days since `apt-get dist-upgrade` is a cross-your-fingers-toes-and-eyes crap shoot, and the in-dev release is pretty darn usable even before the first alpha. Devs should *still* build and test locally of course, but this provides a great backstop, and it does make for a very quick and easy development cycle. -Barry  Even the first day after the stable release <wink>.
