However (and including Simon's comments) I've always found the behaviour
annoying that LilyPond ends with a "failed file" although everything is
running properly.
I would also say that the *possibility* of changed output doesn't
warrant an error, at most a warning. And by the way, if I have a 2.18.2
file and compile it with 2.19.30 the result will be different as well.
So that's not really the issue.
As I see it that message is kind of a reminder that *if* something goes
wrong (when compiling a 2.19. file with 2.18) it *may* be due to the
version mismatch. But again:
- this doesn't justify an error condition
- the same is true the other way round.
My 2 cents
