I believe the 2.x update happened when HC was moved to Claris and we had 
to start buying our copies. At any rate, in order to provide the new 2.7 
features, the file format had to be expanded. There was no room left in 
the old format to do what was needed. Scott Raney had to do the same 
thing several times in MetaCard too, and his updates were not free. I 
never saw any complaints about it; of course, that was a somewhat 
different user base than we have here now.

I rarely release this kind of stack (almost all my work is NDA) but if I 
did, I would save stacks in 2.6 format for at least a while. It's a 
minor thing.

I'm not sure what else they could have done. The old file format was 
full and needed to be extended. What would a 2.6 engine do when it hit 
all the new code in a 2.7 file?
