+* HistoryContainer can now grow
+  dynamically. [PR412](https://github.com/quantopian/zipline/pull/412)
+
+  Calls to `history` will now be able to increase the size or change the shape
+  of the history container to be able to service the call. `add_history` now
+  acts as a preformance hint to pre-allocate sufficient space in the
+  container. This change is backwards compatible with `history`, all existing
+  algorithms should continue to work as intended.
