+ 
+### Added
+- Added new renderers for displaying figures from within the Databricks and CoCalc notebook services ([#1703](https://github.com/plotly/plotly.py/pull/1703))
+- Added `indicator` traces ([plotly/plotly.js#3978](https://github.com/plotly/plotly.js/pull/3978))
+- Added `choroplethmapbox` traces ([plotly/plotly.js#3988](https://github.com/plotly/plotly.js/pull/3988))

+- Added support for `sourcetype` value `raster` and `image` and `type` `raster`
+  for mapbox layout layers ([plotly/plotly.js#4006](https://github.com/plotly/plotly.js/pull/4006))
+- Added `below` attribute to `scattermapbox` traces ([plotly/plotly.js#4058](https://github.com/plotly/plotly.js/pull/4058))
+- Added support for `below: 'traces'` in mapbox layout layers ([plotly/plotly.js#4058](https://github.com/plotly/plotly.js/pull/4058))
+- Added `sourceattribution` attribute to mapbox layout layers ([plotly/plotly.js#4069](https://github.com/plotly/plotly.js/pull/4069))
+- Added `labelangle` and `labelside` attributes to `parcoords` traces ([plotly/plotly.js#3966](https://github.com/plotly/plotly.js/pull/3966))
+- Added `doubleClickDelay` config option ([plotly/plotly.js#3991](https://github.com/plotly/plotly.js/pull/3991))
+- Added `showEditInChartStudio` config option ([plotly/plotly.js#4061](https://github.com/plotly/plotly.js/pull/4061))
+
+### Fixed
+ - Fixed incorrect facet row ordering in figures generated by plotly.express functions ([plotly/plotly_express#129](https://github.com/plotly/plotly_express/issues/129)) 
+ - Fixed "The truth value of an array with more than one element is ambiguous" error when specifying subplot titles as numpy array of strings ([#1685](https://github.com/plotly/plotly.py/pull/1685)). Special thanks to [@MrQubo](https://github.com/MrQubo) for this contribution!
+ - The `line_3d` plotly express function was not visible by default when importing `*` from `plotly.express` ([#1667](https://github.com/plotly/plotly.py/pull/1667/files))
