- As of 0.14.0, ``Float64Index`` is backed by a native ``float64`` dtype

 By default a ``Float64Index`` will be automatically created when passing floating, or mixed-integer-floating values in index creation.
 This enables a pure label-based slicing paradigm that makes ``[],ix,loc`` for scalar indexing and slicing work exactly the
 same.
