+1.20 (IN PROGRESS)
+ - Add new sample program, samples/zoom/zoomscan.pl
+ - samples/zoom/zoomtst1.pl now accepts arbitrary options at
+ the end of the command-line, so that (for example) you can
+ specify a non-USMARC record syntax.
+ - The render() method of ZOOM::Exception(), and therefore the
+ overloaded stringifying operator, deals with exceptions that
+ have no message().
+
+1.19 Mon Jul 9 14:09:31 BST 2007
+ - 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).
+
+1.17 Thu Feb 22 20:38:45 GMT 2007
+ - Change Net::Z3950::ZOOM::event() to allocate its array of
+ connection pointers dynamically, so there is no longer an
+ arbitrary limit of 100.
+ - New connection-level option "_check_debug" emits messages on
+ standard error when checking a connection find an error that
+ is about to result in throwing an exception. There is no
+ reason for you ever to use this, though -- pretend you don't
+ know about it.
