Changes in version 2.3a+ (????-??-??):
* 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.

Changes in version 2.3a, 2006-09-13:
* Bison now supports generating Java parsers. Grammars written for
the Java language should include the `%language "Java"' directive.
* 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.
