BTW: import.c contains the following comment: /* XXX Perhaps the magic number should be frozen and a version field added to the .pyc file header? */
Judging from my decade long experience with exotic image and CAD data formats I think this is always the way to go for binary data files. Using this method newer versions of a program can always recognize the file format version and convert files generated by older versions in an appropriate way.
I have similar experience, notably with hacking graphics file formats. I concur with this recommendation. -- <a href="http://www.tuxedo.org/~esr">Eric S. Raymond</a> The end move in politics is always to pick up a gun. -- R. Buckminster Fuller
