[phobos] Is it time to release a beta?

[Don Clugston]

It's more than a week since bugfix week was announced. There have been
~ 50 commits to Phobos + druntime, and a huge number of important
compiler bugs have been fixed, including the three most important
regressions, and including patches by an unprecedented number of
contributors.
Is it time to prepare a release? Or is there something we still need to do?
