I think I agree with Chris.  The intention is certainly to have a stable
ABI within a stable series, so 3.0.3 should have the same CURRENT.

It's certainly correct that a --disable-deprecated 3.0.3 build has a
different ABI than 3.0.2, and if that were what we were looking at, we
would indeed need the CURRENT version bump; but I think the premise is
wrong: we do *not* have a stable ABI in --disable-deprecated builds, and
we never have.  Otherwise we wouldn't ever be able to deprecate anything
within a stable series.

WDYT about a quick 3.0.4 that restores the CURRENT ?

Cheers,
