I'm talking about 3rd party extensions. Those may require source compatibility with older Python versions. All I'm asking for is to not require source-level use of C99 features. Of course requiring a specific compiler to work with specific CPython versions is fine. On Sat, Jun 4, 2016 at 12:05 PM, Christian Heimes <christian@python.org> wrote:

On Windows extension modules must be compiled with a specific version of MSVC any way. For Python 3.6 VS 2015 or newer is a hard requirement.
We kept the old compiler directories around for embedders.
