-Enhancements
-~~~~~~~~~~~~
-
-* Added masking to :class:`zipline.pipeline.CustomFactor`.
-  Custom factors can now be passed a Filter upon instantiation. This tells the
-  factor to only compute over stocks for which the filter returns True, rather
-  than always computing over the entire universe of stocks. (:issue:`1095`)
-
-* Added :class:`zipline.utils.cache.ExpiringCache`.
-  A cache which wraps entries in a :class:`zipline.utils.cache.CachedObject`,
-  which manages expiration of entries based on the `dt` supplied to the `get`
-  method.
