@jreback Not entirely sure where this should go - Adding x.astype(int) under elif is_bool_dtype(x) higher up throws an error in tests with the existing np.where(x.notna(), x.view(np.int64), np.nan) statement if x is ndarray - it passes if x is Series though.
AttributeError: 'numpy.ndarray' object has no attribute 'isnan'
It passes if adding is_bool_dtype(x) with new np.where condition using ~np.isnan(x) like i've done here to account for x being an ndarray

so don't use np.isnan, change this to
x = np.where(notna(x), x.astype(np.int64, copy=False), np.nan)

I've gone with doing the integer conversion in the elif block higher up and leaving dtype as None as @jschendel suggested, rather than making any changes here.

| - Bug in :meth:`Series.replace` and :meth:`DataFrame.replace` when replacing timezone-aware timestamps using a dict-like replacer (:issue:`27720`) | ||
| - Bug in :meth:`Series.rename` when using a custom type indexer. Now any value that isn't callable or dict-like is treated as a scalar. (:issue:`27814`) | ||
| - :func:`qcut` and `cut` now handle boolean input (:issue:`20303`) |

can you put :func:`cut` as well
