+Changes in version 2.1a:
 
-* Bison-generated C parsers use the _ macro to translate strings from
-  English to the user's language, e.g., _("syntax error").  By default,
-  _ is defined to be a no-op macro so the strings are not translated.
+Changes in version 2.1, 2005-09-16:
+
+* Bison-generated parsers now support the translation of diagnostics like
+  "syntax error" into languages other than English.  The default
+  language is still English.  For details, please see the new
+  Internationalization section of the Bison manual.  Software
+  distributors should also see the new PACKAGING file.  Thanks to
+  Bruno Haible for this new feature.
+
+* Wording in the Bison-generated parsers has been changed slightly to
+  simplify translation.  In particular, the message "memory exhausted"
+  has replaced "parser stack overflow", as the old message was not
+  always accurate for modern Bison-generated parsers.
+
+* Destructors are now called when the parser aborts, for all symbols left
+  behind on the stack.  Also, the start symbol is now destroyed after a
+  successful parse.  In both cases, the behavior was formerly inconsistent.
+
+* When generating verbose diagnostics, Bison-generated parsers no longer
+  quote the literal strings associated with tokens.  For example, for
+  a syntax error associated with '%token NUM "number"' they might
+  print 'syntax error, unexpected number' instead of 'syntax error,
+  unexpected "number"'.

   alloca is used only when compiled with GCC, to avoid portability
   problems as on AIX.

 * When the generated parser lacks debugging code, YYDEBUG is now 0
