-* Changes in version ?.? (????-??-??):
+* Changes in version 2.5 (????-??-??):
 
-**
+** %define can now be invoked via the command line.
+
+  Each of these bison command-line options
+
+    -D NAME=VALUE
+    --define=NAME=VALUE
+
+  is equivalent to this grammar file declaration
+
+    %define NAME "VALUE"
+
+  for any NAME and VALUE.  Omitting `=VALUE' on the command line is
+  equivalent to omitting `"VALUE"' in the declaration.
+
+* Changes in version 2.4.2 (????-??-??):
+
+* Changes in version 2.4.1 (2008-12-11):
+
+** 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.
+
+** A few minor improvements to the Bison manual.
