+* Changes in version 2.4.1 (2008-12-11):
-* %language is an experimental feature.
+** In the GLR defines file, unexpanded M4 macros in the yylval and yylloc
   declarations have been fixed.
 ** Temporary hack for adding a semicolon to the user action.
  Bison used to prepend a trailing semicolon at the end of the user
  action for reductions.  This allowed actions such as
    exp: exp "+" exp { $$ = $1 + $3 };
  instead of
    exp: exp "+" exp { $$ = $1 + $3; };
  Some grammars still depend on this `feature'.  Bison 2.4.1 restores
  the previous behavior in the case of C output (specifically, when
  neither %language or %skeleton or equivalent command-line options
  are used) to leave more time for grammars depending on the old
  behavior to be adjusted.  Future releases of Bison will disable this
  feature.

 These skeletons are the only ones supported by the Bison team.

 finished, *we are not bound to it*.  In particular, Bison is not
 mature enough for us to consider that ``foreign skeletons'' are
 supported.
