To quote my summary email: "This will at least include Visual Studio 2012
on Windows, and Clang 3.1 or GCC 4.7.x on Mac and Linux."

These versions were in my original email and in the release notes update.

The biggest debate has been around 2010 vs. 2012 (we decided 2012 was
viable and desirable), and on which value of 'x' to use in GCC 4.7.x. My
suggestion would be "whatever version of 'x' is on your distro", and if
other distributions come with other versions, we'll test them and try to
make them work. 4.7.0 was fairly broken, but 4.7.1 seems to have been quite
stable and to have gotten into essentially all of the recent releases I've
checked. I've not heard any objections to these versions with specific
problems they present.
