Here are some of my thoughts, Allan:

a particular command, and the resulting program must be tested with
the earliest Stata version with which it is claimed to be compatible.
Unfortunately this is not always the case (testing like that is often
omitted, because only one version of Stata is typically installed).
This is why I keep old versions of Stata installed. If I update one
of my programs on SSC that currently works with Stata 8 or 9, I don't
want to needlessly zap its functionality under those older
versions. It is one thing to take advantage of major new features in
Stata 10, but quite another to have your program break because some
function got a new name in Stata 10. Luckily, Stata isn't that big
as computer programs go, so keeping old versions around isn't that
much of a problem. When I tweak my programs, I rerun some old do
files under different versions of Stata to make sure I am still
getting the same results and don't get errors.
