+*** A skeleton for the D programming language
+  Since a few releases, Bison ships with a stealth experimental skeleton:
+  lalr1.d.  It was first contributed by Oliver Mangold, based on Paolo
+  Bonzini's, and was cleaned and improved thanks to H. S. Teoh.
+  However, for lack of a genuine maintainer, committed to supporting this
+  skeleton (improving, testsing, documenting, etc.), this feature might be
+  DOA.
+  The lalr1.d skeleton *is functional*, and works well, as demonstrated in
+  examples/d/calc.d.  Please try it, enjoy it, and... commit to support it.

   %define variable (disabled by default).
+*** Clean up
+  Several new compiler warnings in the generated output have been avoided.
+  Some unused features are no longer emitted.  Cleaner generated code in

+** Bug Fixes
+*** Crashes when reporting verbose error messages
+  When using %nonassoc, in some situations extremely difficult to reach on

+  about it), the generated parsers could crash.  This is fixed.
