+### Updated
+- [#939](https://github.com/plotly/dash-core-components/pull/939) Upgrade Plotly.js to v2.2.1. Note that this is a major version upgrade to Plotly.js, however we are not treating this as a breaking change for DCC as the majority of breaking changes in Plotly.js do not affect the Dash API. The one exception is that several trace types that have long been deprecated are removed entirely.
+  - [Major release 2.0.0](https://github.com/plotly/plotly.js/releases/tag/v2.0.0):
+    - Stop exporting d3 as `Plotly.d3`, and remove many other deep pieces of the public API. This does not affect the `dcc.Graph` component, but if you make use of `Plotly` from the global scope in some other way you may be affected.
+    - Drop the deprecated trace types `contourgl` and `area`, as well as legacy pre-`scatterpolar` polar attributes `bar.r`, `bar.t`, `scatter.r`, `scatter.t`, `layout.radialaxis`, `layout.angularaxis`. Use `scatterpolar`, `barpolar`, and `polar` subplots instead.
+    - `heatmapgl` and `pointcloud` trace types, and the `transform` attribute are deprecated, and will be removed in a future release.
+    - Increase CSP safety by removing function constructors. 3D plots still use function constructors, but if you place one of the non-3D bundles (including the new `strict` bundle) in your `assets` folder you will have no function constructors.
+    - Remove "Aa" text in legends.
+    - Default `hovermode` to "closest".
+    - Default `textposition` to "auto" in `bar` traces. If you previously used the `bar.text` attribute for hover only, you will need to explicitly set `textposition="none"`.
+    - Add `bar.marker.pattern`, `image.zsmooth`, and various other features and bugfixes.
+  - [Feature release 2.1.0](https://github.com/plotly/plotly.js/releases/tag/v2.1.0):
+    - New `icicle` trace type.
+    - New `legendrank` trace attribute.
+    - Several other additions and bug fixes.
+  - [Feature release 2.2.0](https://github.com/plotly/plotly.js/releases/tag/v2.2.0):
+    - Legend group titles
+    - Half-year directive (`%h`) for date formatting
+    - Several other bug fixes and performance improvements
+  - [Patch release 2.2.1](https://github.com/plotly/plotly.js/releases/tag/v2.2.1) containing a security fix.

 - [#948](https://github.com/plotly/dash-core-components/pull/948)] Adds `disabled_days` prop to `DatePickerRange` and `DatePickerSingle` components. With this prop you can specify days that should be made unselectable in the date picker, in addition to those that fall outside of the range specified by `min_date_allowed` and `max_date_allowed`.
