One case I could see is the use of the requires_python metadata. It was not included in the recent release of Django 2.0 (which is py 3 only) and making a new release will be useless as pip on py2 will still see Django 2.0.0 as Py 2 compatible download it and crash. I'm going to assume with time more packages will be affected even with minor version of Python. -- M On Dec 19, 2017 21:17, "Sumana Harihareswara" <sh@changeset.nyc> wrote: For those who want to track the relevant GitHub issues: * supporting Markdown https://github.com/pypa/warehouse/issues/869 * staged releases https://github.com/pypa/warehouse/issues/726 * advising packagers to run `python setup.py check -r -s` https://github.com/pypa/python-packaging-user-guide/issues/210 -- Sumana Harihareswara Changeset Consulting https://changeset.nyc _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org https://mail.python.org/mailman/listinfo/distutils-sig
