DocDB 8.2.0 released

DocDB now supports additional meta-information for events and sessions. A 2nd
location (Alternate Location) field has been added for things like video
conferencing numbers, virtual rooms, etc. Also, moderators (from the author
list) and topics can be attached to both events and sessions and lists of
events and sessions moderated by an author or on a topic can be retrieved. All
of this information is shown on the event page if present.

Add a new variable HTTP_ENCODING to allow DocDB to say it is unicode or other
character encodings. Set automatically to ISO-8859-1 (default Latin alphabet)
Change a bunch of header lines to enable this
