+1.19 (IN PROGRESS)
+ - Add $conn->exception() method.
+ - Set version number for Net::Z3950 to 0.99 -- less than the
+ 1.0 version number that will be used when it successfully
+ emulates the old Net::Z3950 module, but superseding the last
+ release, 0.51, of that module.
+ - Include samples/zoom/zdump.pl in distribution.
+ - Add "irspy" namespace to samples/zoom/zselect
+
+1.18 Mon Feb 26 14:57:48 GMT 2007
+ - When a connection is in asynchronous mode, failing
+ operations (search, scan, etc.) no longer throw exceptions.
+ This is because the event-loop in asychronous applications
+ needs to check for errors anyway, in case the server has
+ returned high-level diagnostics such as "unsupported use
+ attribute". So this check within the event-loop is now the
+ only place where error-checking need be done.
+ - Add new public ZOOM::Connection() function, check(), which
+ throws an exception if an error is pending (even if the
+ connection is asynchronous).
+ - New YAZ logging level, "zoom_check", notes when errors are
+ detected and either left unreported (asynchronous
+ connections) or thrown as exception (synchronous).
