Except perhaps in scale. The same people that upgrade from 3.x to 3.x+1 without giving it a second thought, just to be on the latest version, will hesitate to go from 3.x to 4.y, because the major version change is a hint that they should be more careful. That means they're ready for it when they get the ModuleNotFoundError exception, instead of feeling ambushed. OK, it may be that this is not enough to warrant a 4.0 release, but I do think python-dev should get over its fear of major versions sometime. And that transitioning to a leaner standard library with some things moved to PyPI would not be a bad program statement for a Python 4.0. regards, Anders _______________________________________________ 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
