Proposed errrata & minor admentments for PEP 425 can be submitted as a PyPUG issue with a PR against https://packaging.python.org/en/latest/specifications/#platform-compatibility-tags (the actual technical details of the proposed changes should still be discussed here) This does remind me I have unfinished work in officially amending that spec management process, though: https://github.com/pypa/pypa.io/issues/11#issuecomment-195412332 Regards, Nick. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org https://mail.python.org/mailman/listinfo/distutils-sig
