+ - Add new functions Net::Z3950::ZOOM::diag_srw_str() and
+ ZOOM::diag_srw_str() to map SRW diagnostic codes into
+ human-readable messages.
+ - ZOOM::Exception() constructor uses diag_srw_str() to fill in
+ the error message, if it is undefined, for SRW errors.
+ - The render() method of ZOOM::Exception(), and therefore the
+ overloaded stringifying operator, deals with exceptions that
+ have no message().
+ - Corrected the scan parts of the test-suite that use CQL so
+ that they explicitly perform client-side CQL compilation and
+ send the resulting Type-1 query. Previously, these tests
+ were (accidentally) requesting that CQL be sent as-is to the
+ server, but this mistake was being masked by an error in
+ older versions of ZOOM-C that compiled client-side anyway!
