 Changes in version 2.3+:
 
+* Except for LALR(1) parsers in C with POSIX Yacc emulation enabled (with `-y',
+  `--yacc', or `%yacc'), Bison no longer generates #define statements for
+  associating token numbers with token names.  Removing the #define statements
+  helps to sanitize the global namespace during preprocessing, but POSIX Yacc
+  requires them.  Bison still generates an enum for token names in all cases.
+
 * The option `--report=look-ahead' has been changed to `--report=lookahead'.
   The old spelling still works, but is not documented and may be removed
   in a future release.
