 	- Some clarifications to documentation.
 	- 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.
