I often talk about "Python 4000" as the next possible opportunity for major backwards incompatible changes, but of course that's not decided yet, and given the long term pain of the 2->3 transition, it may be quite conservative, with no radical changes. Perhaps I ought to use Python 5000 as my target for radical language changes? > For example, I propose to release the next major Python version (3.5) > with the version 4.0 but without removing anything. (It's just an > example, it can wait another release.) If Python 4 is a conservative release, I don't see any reason to bump the major version number until after Python 3.9. So, assuming no further radical changes to the language like 2->3, we'd have five more point releases before needing to deal with 4.0. Perhaps we need a long-term schedule? 3.5: August 2015 3.6: February 2017 3.7: August 2018 3.8: February 2020 3.9: August 2021 4.0: February 2023 give or take a few months. -- Steven _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
