+Revision history for Perl extension Net::Z3950::ZOOM.
+
+1.06 IN PROGRESS
+ - Avoid mixed statement/declaration in ZOOM.xs. *sigh* Why
+ the heck GCC allows this by default I will never understand.
+ - Add (commented out) OPTIMIZE option to Makefile.PL, to turn
+ on -Wdeclaration-after-statement, which makes mixed
+ statement/declaration illegal.
+
+1.05 Wed Apr 12 13:31:27 BST 2006
+ - 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. Additional sample
+ programs "async.pl" and "trivial-async.pl" for the ZOOM
+ interface only, the latter being a "shortest possible
+ broadcast search application".
+ - Added documentation on writing asynchronous applications.
+ - Added test-scripts "t/19-events.t" and "t/29-event.t" for
+ events on an asynchronous connection.
+ - Fix ZOOM::Connection::new so that options are handled in
+ accordance with the documentation: applied _before_ the
+ connection is forged, so that "async" and similar options
+ can take effect.
+
+1.04 Mon Apr 3 14:56:11 BST 2006
+ - The ZOOM-Perl layer now provides access to the underlying
+ ZOOM-C's character-translation functionality, through new
+ optional arguments to ZOOM::Record's render() and raw()
+ methods, and a new underlying get() method.
+
+1.03 Thu Mar 9 12:55:23 GMT 2006
+ - Allow additional key => value pairs as arguments to the
+ ZOOM::Connectoion constructor; these are added as Connection
+ options before the protocol connection is forged.
+
+1.02 Thu Mar 9 11:36:55 GMT 2006
+ - Add interface to yaz_version().
+ - Emit big warning at startup time if YAZ version is less than
+ 2.0.11 (which is what ZOOM-Perl 1.02 requires) unless the
+ file /tmp/ignore-ZOOM-YAZ-version-mismatch exists.
+ - Fix incorrect ZOOM-package URL in documentation.
+ - Fix typo ("createdb" package) in documentation.
+ - The ZOOM::Connection constructor may now be called with only
+ a single argument (host-string) and does not require a
+ dummy port-number argument.
+
+1.01 Thu Dec 22 14:13:34 GMT 2005
+ - Place some CODE: chunks in "ZOOM.xs" inside curly brackets
+ so that the declarations they begin with are at the start of
+ the block. This avoid mixed code/declarations. (The
+ "correct" solution is to use INIT: clauses in the XS file,
+ but they don't seem to work: the code in them is slapped
+ down right next to the CODE:, so declarations are not
+ acceptable there either.)
+ - 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().
+ - The tests t/15-scan.t and t/25-scan.t now also test for
+ scanning by CQL query. To support these tests, a new files
+ is added to the distribution, "samples/cql/pqf.properties"
+ - Remove nonsensical clause about CQL sort-specifications from
+ the documentation.
+ - Add new function Net::Z3950::ZOOM::query_cql2rpn(), for
+ client-side CQL compilation.
+ - Add new ZOOM::Query::CQL2RPN class, encapsulating CQL
+ compiler functionality as a Query subclass.
+ - Add two new error-codes, CQL_PARSE and CQL_TRANSFORM,
+ returned by the client-side CQL facilities.
+ - The test-scripts t/12-query.t and t/22-query.t are extended
+ to also test client-side CQL compilation.
+ - Add all the yaz_log*() functions within the Net::Z3950::ZOOM
+ namespace.
+ - Add new ZOOM::Log class for logging, providing aliases for
+ the functions in the Net::Z3950::ZOOM layer.
+ - Add diagnostic set to rendering of Exception objects.
+ - Documentation added for CQL compilation and logging.
+
+1.00 Wed Dec 14 11:18:33 GMT 2005
+ - First distributed version.
