No, we're issuing a warning about old API versions but still try to work with them. After all most extensions don't create frame or code objects. I added the flags for the tp_richcompare field when I tried 2.1a1 with Zope's ExtensionClasses and Acquisition modules. Turns out I cot a core dump, while 2.1 ran flawlessly. The reason: they have their own type struct which has the same lay-out as the Python 1.5.2 (or even older) type struct, followed by fields of their own. They have the tp_flags field set to 0, so up to 2.0, it was compatible. I expect that 2.1a2 will work with the unchanged Zope code because of the flag I added. --Guido van Rossum (home page: http://www.python.org/~guido/)
