It's going to be better, starting from Python 3.5; Microsoft is
guaranteeing a measure of binary compatibility for future compiler
versions. Unfortunately the guarantee requires some internal changes,
so it's moving forward only, not backward. The fate of Python 2.7 is
very much up in the air, because the compiler that was used for 2.7.0
won't be supported in 2020 (I think it might be already out of
support), so there's a big question of whether or not to change
compilers in the middle of a minor version. Neither option is good.
