-* Bison can no longer be built by a K&R C compiler; it requires C89 or
-  later to be built.  This change originally took place a few versions
-  ago, but nobody noticed until we recently asked someone to try
-  building Bison with a K&R C compiler.
+* %destructor
+  It is now possible to reclaim the memory associated to symbols
+  discarded during error recovery.  This feature is still experimental.
+
+* Bison now parses C99 lexical constructs like UCNs and
+  backslash-newline within C escape sequences, as POSIX 1003.1-2001 requires.
+
+* --no-line works properly.

 
 * %error-verbose
   This new directive is preferred over YYERROR_VERBOSE.

+  #defining yyerror to steal internal variables is strongly
+  discouraged.  It is not guaranteed to work for ever.

+* #line
+  Bison now recognizes #line in its input, and forwards them.
+
+* #line
+  File names are properly escaped. E.g. foo\bar.y give #line 123 "foo\\bar.y".
