Other enhancements
^^^^^^^^^^^^^^^^^^

- :meth:`IntegerArray.astype` now supports ``datetime64`` dtype (:issue:`32538`)
- :class:`IntegerArray` now implements the ``sum`` operation (:issue:`33172`)
- Added :class:`pandas.errors.InvalidIndexError` (:issue:`34570`).
- Added :meth:`DataFrame.value_counts` (:issue:`5377`)
- Added a :func:`pandas.api.indexers.FixedForwardWindowIndexer` class to support forward-looking windows during ``rolling`` operations.

- Bug in :meth:`DataFrame.append` when appending a :class:`Series` containing a scalar tz-aware :class:`Timestamp` to an empty :class:`DataFrame` resulted in an object column instead of datetime64[ns, tz] dtype (:issue:`35038`)
- ``OutOfBoundsDatetime`` issues an improved error message when timestamp is out of implementation bounds. (:issue:`32967`)
