-* Changes in version 2.5.1_rc1 (2012-05-14):
+* Noteworthy changes in release ?.? (????-??-??) [?]
+
+** Future changes:
+
+  The next major release will drop support for generating parsers in K&R C,
+  and remove the definition of yystype (removal announced since Bison
+  1.875).
+
+** The generated header is included (yacc.c)
+
+  Instead of duplicating the content of the generated header (definition of
+  YYSTYPE, yyltype etc.), the generated parser now includes it, as was
+  already the case for GLR or C++ parsers.
+
+** Headers (yacc.c, glr.c, glr.cc)
+
+*** Guards
+
+  The generated headers are now guarded, as is already the case for C++
+  parsers (lalr1.cc).  For intance, with --defines=foo.h:
+
+  #ifndef YY_FOO_H
+  # define YY_FOO_H
+  ...
+  #endif /* !YY_FOO_H  */
+
+*** New declarations
+
+  The generated header now declares yydebug and yyparse.  Both honor
+  --name-prefix=bar_, and yield
+
+  int bar_parse (void);
+
+  rather than
+
+  #define yyparse bar_parse
+  int yyparse (void);
+
+  in order to facilitate the inclusion of several parser headers inside a
+  single compilation unit.
+
+* Noteworthy changes in release 2.5.1 (2012-06-05) [stable]
