My own little tidbit on this: I have Stata 7, 8, 9 and 10 on my 
computer.  I have routines on SSC that work on Stata 8.  If I tweak 
those programs, I do it in 10, but then I go back and run some tests 
using Stata 8.  I figure I don't want to zap the program 
unnecessarily for Stata 8 users.  If I find I have zapped it, I find 
the fix is usually pretty straightforward, e.g. I have to find the 
Stata 8 name for some function that got renamed by Stata 10; or use 
slightly different code that accomplishes the same thing.
If I was doing really major changes though, I would probably just 
create a Stata 8 version whose code was frozen and require that users 
of the new version use Stata 10 or higher.
