[boost] Have we lost a bunch of testers recently?

I'm looking at http://www.boost.org/development/tests/develop/developer/bind.html and I have the feeling that a bunch of columns that used to be there no longer are. I see no tests on OS X, for instance, no tests from Sandia at all, and very slim C++11 coverage. Is this related in some way to the cleanup of old test results perhaps?
