 * 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.

+
+  > SIDData now has methods for:
+
+  > - `stddev`
+  > - `mavg`
+  > - `vwap`
+  > - `returns`
+
+  > These methods, except for `returns`, accept a number of days. If you are
+  > running with minute data, then this will calculate the number of minutes in
+  > those days, accounting for early closes and the current time and apply the
+  > transform over the set of minutes. `returns` takes no parameters and will
+  > return the daily returns of the given security.
+
+  > Example:
+  > ```
+  > # The standard deviation of the price in the last 3 days.
+  > data[security].stdev(3)
+  > ```
