+ for more information.
+ 
+### Added
+ - Added new `auto_play` argument to offline `plot` and `iplot` to control
+ whether figures with frames are automatically animated when the figure is
+ loaded
+ ([#1447](https://github.com/plotly/plotly.py/pull/1447))
+ - Added support for uploading "offline" animations (those with inline data
+ arrays rather than grid references) to Chart Studio using `plotly.plotly.create_animations`

+ 
+### Updated

+ 
+### Fixed
