*** POTENTIAL INCOMPATIBILITY ***
There is no more ClassPtr classes, so, if in the past you
needed to resort in some kind of trick to use, or overcome
their presence, it is no longer needed, but the extra code
you added could break.
There is no more ClassPtr classes in the python code. Hence,
if in the past you needed to resort in some kind of trick
to use them, or overcome their presence, it is no longer
required, but the extra code you added could now break
things arounds.
If needed, you can use the option -classptr, i.e.,
swig -classptr -python ...
to generate the old ClassPtr classes.
