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.
