Hi Laurent how can I help / convince you to get rpy2 3.x working on windows? I have invested heavily in rpy2 so don’t want to switch but need this to work on windows and my environments are no longer solving so I’m in a bind. Are you dropping windows support for good or is this a temporary glitch? And I’m happy to help but I’m fairly new at this. Please let me know. Thanks.
