+ - Add new function Net::Z3950::ZOOM::connection_scan1(), which
+ uses a query object to indicate the start-term. This opens
+ the way for using CQL queries for scanning once the
+ underlying ZOOM-C code supports this.
+ - NOTE BACKWARDS-INCOMPATIBLE CHANGE: The ZOOM::Connection
+ method scan() is renamed scan_pqf(), and a new scan() method
+ is introduced which calls the underlying scan1() function.
+ Thus the scan()/scan_pqf() dichotomy is consistent with that
+ between search()/search_pqf().
