Minor releases?

[David Raleigh Arnold]

I don't see any straightforward way of seeing a changelog or
anything which tells the differences between minor releases.
I think I can justify x.x.1 on one machine and x.x.2 on
another, but I would like to know what the differences are
to avoid open manholes.  Is there a CHANGELOG somewhere, 
and wouldn't it be a good idea to have that information on
the Documentation or Download page in some form?  Regards, daveA
