Release Notes: This version adds a documented example of how to enable secure search. It is modified to avoid passing arguments explicitly by reference, and to remove use of the PHP short open tag.
Release Notes: This release has a secure search option to make it work with recent versions of htsearch that do not allow custom configurations to be used from the CGI interface. An option has been added to specify the path of the htsearch program, which may differ from that of the of htdig program. The htdig automatic version detection algorithm before indexing has been improved.
