There is a documentation archive at:
http://code.google.com/apis/searchappliance/documentation/archive.html
However it only goes back as far as version 4.6
How can I get a copy of the documentation for an earlier release?
(In this instance, a client tells me they are running Google Mini
Software Version 4.4.102.M.36, and I would like to determine what that
entails before going any further.)
Tangentially, how can I find a list of the hardware versions mapped to
the most recent software version they can be upgraded to?
