 * Bison should now work on 64-bit hosts.
 
+* Indonesian translation thanks to Tedi Heriyanto.
+
+* GLR parsers
+  Fix spurious parse errors.
+
+* Pure parsers
+  Some people redefine yyerror to steal yyparse' private variables.
+  Reenable this trick until an official feature replaces it.
+
+* Type Clashes
+  In agreement with POSIX and with other Yaccs, leaving a default
+  action is valid when $$ is untyped, and $1 typed:
+
+       untyped: ... typed;
+
+  but the converse remains an error:
+
+       typed: ... untyped;
+
+* Values of mid-rule actions
+  The following code:
+
+       foo: { ... } { $$ = $1; } ...
+
+  was incorrectly rejected: $1 is defined in the second mid-rule
+  action, and is equal to the $$ of the first mid-rule action.
