Yes, it does, because the final release may be significantly different
from the pre-released versions. It is not unheard of entire features
being removed or modified in the final release.

Personally, I think MSVC already consumes too much effort to support its
new versions. For example, I don't see as much fuss about testing gcc or
clang pre-releases - these get introduced silently to the test matrix,
with apparently no required changes to Boost.Build or Boost.Config.
(Well, the latter may need to be updated if a previously missing/broken
feature is supported in the new compiler, but that is not a showstopper.)
