Distribution docs for next release

[Peter Stephenson <p.stephenson@xxxxxxxxxxx>]

It's high time we made a new release.  Here are some updates to the
distribution and I'll make a test release over the next few days.

I believe there's still some stuff from slightly before Christmas that
hasn't been properly sorted out.  I don't think anything was urgent ---
we can pick it up again after Easter.
