 1. Instantiating using a numpy numeric array now follows the dtype of the numpy array.
    Previously, all indexes created from numpy numeric arrays were forced to 64-bit. Now,
-   the index dtype follows the dtype of the numpy array. For example, it would for all
-   signed integer arrays previously return an index with ``int64`` dtype, but will now
-   reuse the dtype of the supplied numpy array. So ``Index(np.array([1, 2, 3]))`` will be ``int32`` on 32-bit systems.
+   for example, ``Index(np.array([1, 2, 3]))`` will be ``int32`` on 32-bit systems, where

    Instantiating :class:`Index` using a list of numbers will still return 64bit dtypes,
    e.g. ``Index([1, 2, 3])`` will have a ``int64`` dtype, which is the same as previously.
