 Revision history for Perl extension Net::Z3950::SimpleServer
 
+1.10  Tue Mar  3 22:47:16 GMT 2009
+       - Document the init-handler's PEER_NAME argument.
+       - Update URL into YAZ documentation.
+       - bend_delete() no longer returns without value.
+       - Route around ActivePerl's damage to the "open" symbol.
+
+1.09  Mon Sep 10 15:54:38 BST 2007
+       - *Argh*  Another mixed statement/declaration.
+
+1.08  Mon Sep 10 12:15:29 BST 2007
+       - *Sigh*  Fix mixed statement/declaration.
+
+1.07  Sat Sep  1 10:31:26 BST 2007
+       - When the scan-handler callback returns, do not attempt to
+         copy the terms from Perl structures if the error-code is
+         non-zero (i.e. if an error has occurred).  This protects
+         against a segmentation fault when the Perl callback does not
+         explicitly set $args->{NUMBER} = 0 on error.
+       - Correct transcription of string-valued attributes in
+         $args->{RPN}.
+       - Scan handler is now passed RPN as well as TERM, a tree of
+         Perl structures representing the entire scan clause
+         including access-points and other attributes (which are
+         discarded from TERM).
+       - The various classes used to represent nodes in the RPN query
+         tree (Net::Z3950::APDU::Query, Net::Z3950::RPN::And,
+         Net::Z3950::RPN::Or, Net::Z3950::RPN::AndNot,
+         Net::Z3950::RPN::Term and Net::Z3950::RPN::RSID) now all
+         share a newly introduced superclass Net::Z3950::RPN::Node,
+         making it possible to write methods that apply to all node
+         types.
+       - A utility method toPQF() is provided for
+         Net::Z3950::RPN::Node, enabling the RPN tree to be converted
+         back into a flat PQF query.
+       - Add support for the Delete Result Set service.
+       - Add documentation for the Sort service.
+       - Some clarifications to documentation.
+
+1.06  Fri Aug 10 23:30:00 BST 2007
+       - New global-handle element can be specified when creating a
+         simple-server object and will be passed to all callback
+         functions.  This allows global state to be eliminated from
+         SimpleServer applications ... finally!
+       - Search handler now deals correctly with undefined addinfo:
+         previously a (harmless) error message was emitted.
+       - Add Perl API to yaz_diag_srw_to_bib1(), which SimpleServer
+         applications will need if they access SRU/SRW back-end
+         databases and need to report errors.
+       - Add Perl API to yaz_diag_bib1_to_srw(), because it would
+         seem churlish not to.
+
+1.05  Wed Dec 27 13:19:13 CET 2006
+        - Taking new naming convention for YAZ constants into account.
+
 1.04  Fri Dec  1 10:48:32 CET 2006
         - Build such that SimpleServer links to new yaz shared object.
