+** %language is no longer an experimental feature.
+
+  The introduction of this feature, in 2.4, was four years ago. The --language
+  option and the %language directive are no longer experimental.
+
+** New format for error reports: carets
+
+  Caret errors have been added to Bison, for example (taken from the
+  documentation):
+
+    input.y:3.20-23: error: ambiguous reference: '$exp'
+     exp: exp '+' exp { $exp = $1 + $2; };
+                        ^^^^
+
+  The default behaviour for now is still not to display these unless explictly
+  asked with -fall of -fcaret. However, in a later release, it will be made the
+  default behavior (but may still be deactivated with -fno-caret).
+
+** 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".
