   metadata going forward, explicitly use `metadata(dims(obj, X))`
 - `val(obj)` no longer returns `map(val, dims(obj))` because that's just weird,
   val seems like it would return `parent` from that call. `lookup` does this anyway.
+- Added a `D` parameter to AbstractDimStack in ([#1128]) so that its more
+  interoperable with AbstractDimArray
 - Removed two methods that don't have much use and cause lots of invalidations:
   - `Base.convert(Type{<:AbstractString}, name::DD.AbstractName)` is removed, use `string(name)` instead.
   - `Base.merge(stack::AbstractDimStack, pairs)` is removed, use `merge(stack, NamedTuple(pairs))` instead.
