OK, so I have removed Richard's items from the wiki page (since they're now
in the manual) and added items I have gathered from reviewing all of the 
git commits in the release. Let me know if you need clarification on anything
- everyone else, let us know if I missed or messed up something.

BTW I think the section on postinstalls (from Richard's input) is a little terse
and needs expansion - most importantly it needs to describe what actions the
user might need to take. I'll take care of this on review if nobody else does.

Cheers,
Paul
