OK, out of interest when working on a theoretical 1.0.3 where are you
going to do this, in the head of Release-1-0 ? This is OK, but I think
there should have been a Release-1-0-0 which is treated as read-only,
otherwise it isn't possible to discover what was in the original
Release-1-0-0. 

Just putting my two cents in, in case there is ever a 2.0.0.
