+* Previously, Bison sometimes generated parser tables with states that were
+  unreachable due to conflicts in predecessor states.  Bison now:
+
+    1. Removes unreachable states.
+
+    2. Does not report any conflicts that appeared in unreachable states.
+       WARNING: As a result, you may need to update %expect and %expect-rr
+       directives in existing grammar files.
+
+    3. For any rule used only in such states, Bison now reports the rule as
+       "never reduced because of conflicts".

 * The -g and --graph options now output graphs in Graphviz DOT format,
   not VCG format.

 * Instead of %union, you can define and use your own union type
   YYSTYPE if your grammar contains at least one <type> tag.
   Your YYSTYPE need not be a macro; it can be a typedef.
