[CC-ing cython-devel, but please keep the discussion on cython-users] Hi all,
we were recently asked on the bug tracker [1] when Cython is planning to end its support for Python 2.x, so I'd like to get some more user opinions on this. We are planning to release Cython 3.0 this year [2], with some well selected backwards incompatible changes and a tiny bit of feature reduction, so … wouldn't that be a good time to cut off even more of the old cruft? Should we really have a release that supports the CPython versions 3.8 (~October) all the way back to 2.7? Or would Python 2.7-3.7 be enough in 0.29, and only Python 3.[345]-3.8+ for Cython 3.0? (*) Remember, removing legacy support as part of a new release doesn't change anything about the old releases, so they will still keep working for everyone who wants Python 2.x support, even long after January 1st, 2020. As I wrote in the ticket, I would not object to anyone backporting fixes to 0.29 that we implement for newer releases, and continuing with point releases for it whenever there is something to release in the legacy maintenance branch. (And as long as there aren't any breaking changes in Py3.8, 0.29.x might also work there.) What do you think?

Py3.4 is expected to reach its EOL in March, but still seems worth supporting for another while. Not sure about 3.3, probably an "as long as it doesn't hurt" case. _______________________________________________ cython-devel mailing list cython-devel@python.org https://mail.python.org/mailman/listinfo/cython-devel
