+ - Implementation of asynchronous events! The Net::Z3950::ZOOM
+ interface provides this through the event, last_event() and
+ event_str() functions. The ZOOM interface provides it
+ through the ZOOM::event() and ZOOM:event_str() functions,
+ and the ZOOM::Connection class's last_event() function.
+ - New sample programs added illustrating both asynchronous
+ interfaces: samples/net-z3950-zoom/zoomtst3.pl and
+ samples/zoom/zoomtst3.pl respectively.
