* Noteworthy changes in release ?.? (????-??-??) [?]
+** New value for %define variable: api.pure full
+
+ The %define variable api.pure requests a pure (reentrant) parser. However,
+ for historical reasons, using it in a location-tracking Yacc parser resulted
+ in an yyerror function that did not take a location as a parameter. With this
+ new value, the user may request a better pure parser, where yyerror does take
+ a location as a parameter (in location-tracking parsers).
+
+ The use of "%define api.pure true" is deprecated in favor of this new
+ "%define api.pure full".
+
** Changes in the format of error messages
This used to be the format of many error reports:
position_type are deprecated in favor of api.location.type and
api.position.type.
-** Graphviz improvements
+** Graph improvements in DOT and XSLT
The graphical presentation of the states is more readable: their shape is
now rectangular, the state number is clearly displayed, and the items are
The reductions are now explicitly represented as transitions to other
diamond shaped nodes.
+ These changes are present in both --graph output and xml2dot.xsl XSLT
+ processing, with minor (documented) differences.
+
+ Two nodes were added to the documentation: Xml and Graphviz.
