-  It is always recommended to prefer `%define api.value.type foo` to
-  `#define YYSTYPE foo`.  The latter is supported in C for compatibility
-  with Yacc, but not in C++.  Warnings are now issued if `#define YYSTYPE`

-  Support for the YYPRINT macro is removed. It worked only with yacc.c and

   In conformance with the recommendations of the Graphviz team

   now generates a *.gv file by default, instead of *.dot.  A transition

 ** New features
 
+*** A skeleton for the D programming language
+
+  The "lalr1.d" skeleton is now officially part of Bison.
+
+  It was originally contributed by Oliver Mangold, based on Paolo Bonzini's
+  lalr1.java, and was improved by H. S. Teoh.  Adela Vais then took over
+  maintenance and invested a lot of efforts to complete, test and document
+  it.
+
+  It now supports all the bells and whistles of the other deterministic
+  parsers, which include: pull/push interfaces, verbose and custom error
+  messages, lookahead correction, token constructors, internationalization,
+  locations, printers, token and symbol prefixes, etc.
+
+  Two examples demonstrate the D parsers: a basic one (examples/d/simple),
+  and an advanced one (examples/d/calc).
