DocDB 7.5.1 Released

7.5.1
Two new perl modules are required for this release:
"XML::Twig" and "HTML::TreeBuilder"
Use the "CheckModules" script to verify installation.

Added the quick search to the homepage instead of the link to "Search" Link is
also there as "Advanced"

Added an XML output version of Search which will be used in the meta-search to
be added in the version 7.6.0

Add option for removing all subordinate groups of a group. Otherwise, once
a subordinate group was set for a group, that group always had to have at
least one. Also change help to better explain what is going on with groups.

A somewhat simpler user interface for administering personal account
(certificates, email notifications. You can still use the old form if you
know what user you want to act on and what you want to change. But, if you
click on the person's name in the summary table that follows, you get a
slightly simpler form for just that one person that (especially) makes adding
or removing a group easier.
