+### Updated
+- [#2016](https://github.com/plotly/dash/pull/2016) Widespread dependency upgrades
+  - Upgrade Plotly.js to v2.11.1 (from v2.11.0). Patch release [2.11.1](https://github.com/plotly/plotly.js/releases/tag/v2.11.1) fixes regl-based traces in strict CSP mode, however you must manually switch to the strict bundle to use this.
+  - Upgrade `black` to v22.3.0 for Python 3.7+ - if you use `dash[ci]` and you call `black`, this may alter your code formatting slightly, including more consistently breaking Python 2 compatibility.
+  - Many other mainly JS dependency upgrades to the internals of Dash renderer and components. These may patch bugs or improve performance.

     - `fillpattern` for `scatter` traces with filled area
   - [Feature release 2.11.0](https://github.com/plotly/plotly.js/releases/tag/v2.11.0):
     - Every trace type can now be rendered in a stricter CSP environment, specifically avoiding `unsafe-eval`. Please note: the `regl`-based traces (`scattergl`, `scatterpolargl`, `parcoords`, and `splom`) are only strict in the `strict` bundle, which is NOT served by default in Dash. To use this bundle with Dash, you must either download it and put it in your `assets/` folder, or include it as an `external_script` from the CDN: https://cdn.plot.ly/plotly-strict-2.11.0.min.js. All other trace types are strict in the normal bundle.
