        + Chg : A large chunk of boilerplate XS code, which is also used in
                other XS modules, has been factored out of the main .xs file
                to a collection of .h files in the xsh subdirectory.
        + Fix : [RT #128989] : Bleadperl v5.25.3-266-g1d7e644 breaks V::M.
                Len magic is no longer called for negative array indices
                fetches, so the relevant tests are now skipped.
                Thanks Andreas Koenig for reporting.
