I agree in general, but Ivy 2 has been going in a deep code change, and we
decided to keep backward compatibility with 1.4 at ant tasks level, but not
at API level. We warned the users about that in the release notes, and
changing code in Ivy for backward compatibility with a beta  version (which
in Ivy language is not a release candidate) sounds not like a good idea to
me. But once again I'm alone to decide, and if more people think it makes
sense, I won't object.

Indeed.

Yes, in a way. That's the problem of using a beta version as a dependency.
And that's also a problem of long release cycles, I'd really like to get Ivy
2 final released asap to avoid or at least reduce this kind of problem in
the future.

This sounds like a good option.
