There is 0.20 and 0.20-fixes.   Early 0.20-fixes packages would work 
with a 0.20 base release, but later 0.20-fixes packages include a change 
that bumped the protocol version.  As such, you need 0.20-fixes packages 
on all your machines that include that change or later.  Best case and 
the only one supported is that all your systems are running the same 
release/package of 0.20-fixes.
