* :class:`~zipline.assets.assets.AssetFinder` speedups (:issue:`830` and
:issue:`817`).
* Improved support for non-float dtypes in Pipeline. Most notably, we now
support ``datetime64`` and ``int64`` dtypes for ``Factor``, and
``BoundColumn.latest`` now returns a proper ``Filter`` object when the column
is of dtype ``bool``.

``float``, ``datetime``, and ``bool`` Pipeline terms. (:issue:`962`)
