But not in 3.2. And the new API appeared in 2.7. That is a deprecation period of seven and a half months. > If you go from 2.7 to 3.2, you should expect things to break.

Yes, but we are now in a period of parallell support for Python 2 and Python 3. So it doesn't work like that. We need to support both Python 2 and Python 3 at the same time. Therefore, the deprecation period was seven and a half month, because it was impossible to support the new API before, and impossible to support the new API after, if you need to support both Python 2 and Python 3. >> Let's make no bones about this: The PyCObject API should *not* have >> been removed in 3.2.

It is too short, and so is 19 months, but this change does *not* conform. //Lennart _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
