 ### Updated
   - Updated Plotly.js to from version 2.17.1 to version 2.18.0. See the [plotly.js CHANGELOG](https://github.com/plotly/plotly.js/blob/master/CHANGELOG.md#2180----2023-01-19) for more information. Notable changes include:
     - Add `sync` tickmode option [[#6356](https://github.com/plotly/plotly.js/pull/6356), [#6443](https://github.com/plotly/plotly.js/pull/6443)], with thanks to @filipesantiagoAM and @VictorBezak for the contribution!
+  - Build process now uses Node 18.x and version 2 lockfile (should be an invisible change for users) [[#4034](https://github.com/plotly/plotly.py/pull/4034)]
+
+### Fixed
+  - `write_html()` now explicitly encodes output as UTF-8 because Plotly.js' bundle contains such characters [[#4021](https://github.com/plotly/plotly.py/pull/4021)] and [[#4022](https://github.com/plotly/plotly.py/pull/4022)]
+  - fixed `iframe` renderer regression from 5.12 and also fixed error when this renderer was used in the very first cell in a notebook [[#4036](https://github.com/plotly/plotly.py/pull/4036)]
