I've just uploaded 0.90.06 to the downloads section on
www.stonekeep.com.
Primarily this includes all the bugfixes and updates I've been posting
over the last couple weeks (see the keystone-dev mailing list archives
for summaries).

I've also started keeping a CHANGELOG, which only has one or two rows
in
it, but as I'll try to keep it up to date.
