[erlang-questions] R14B03 compiled code vs R15B compiled code

[Wes James]

I've been pushing some R15B compiled code to some workstations that
have R14B03 on them, but they crash when run.  If I take my code and
compile it on the R14B03 system and run it, it does not crash.  What
is the compatibility between versions?  I don't remember having any
issue in the past between versions (like R14 and R13).

Thanks,
