+## [5.19.0] - 2024-02-15
+
+### Updated
+
+- Updated Plotly.js from version 2.27.0 to version 2.29.1. See the [plotly.js CHANGELOG](https://github.com/plotly/plotly.js/blob/master/CHANGELOG.md#2291----2024-02-12) for more information. These changes are reflected in the auto-generated `plotly.graph_objects` module. Notable changes include:
+  - Add `layout.barcornerradius` and `trace.marker.cornerradius` properties to support rounding the corners of bar traces [[#6761](https://github.com/plotly/plotly.js/pull/6761)],
+   with thanks to [Displayr](https://www.displayr.com) for sponsoring development!
+  - Add `autotickangles` to cartesian and radial axes [[#6790](https://github.com/plotly/plotly.js/pull/6790)], with thanks to @my-tien for the contribution!
+  - Add `align` option to sankey nodes to control horizontal alignment [[#6800](https://github.com/plotly/plotly.js/pull/6800)],
+   with thanks to @adamreeve for the contribution!
+  - Add the possibility of loading "virtual-webgl" script for WebGL 1 to help display several WebGL contexts on a page [[#6784](https://github.com/plotly/plotly.js/pull/6784)], with thanks to @greggman for the contribution!
+  - Add options to use base64 encoding (`bdata`) and `shape` (for 2 dimensional arrays) to declare various typed arrays i.e. `dtype=(float64|float32|int32|int16|int8|uint32|uint16|uint8)` [[#5230](https://github.com/plotly/plotly.js/pull/5230)]
+  -  Adjust stamen styles to point to `stadiamaps.com`, the users may also need to provide their own API_KEY via `config.mapboxAccessToken` [[#6776](https://github.com/plotly/plotly.js/pull/6776), [#6778](https://github.com/plotly/plotly.js/pull/6778)]
+- Removed Python 3.6 and Python 3.7 support [[#4492](https://github.com/plotly/plotly.py/pull/4492)]
+
+### Fixed
+- Ensure scatter `mode` is deterministic from `px` [[#4429](https://github.com/plotly/plotly.py/pull/4429)]
+- Fix issue with creating dendrogram in subplots [[#4411](https://github.com/plotly/plotly.py/pull/4411)],
+- Fix issue with px.line not accepting "spline" line shape [[#2812](https://github.com/plotly/plotly.py/issues/2812)]
+- Fix KeyError when using column of `pd.Categorical` dtype with unobserved categories [[#4437](https://github.com/plotly/plotly.py/pull/4437)]
+- Fix dataframe interchange in case `column_names` returns an unmaterialized object: generator, iterator, etc. [[#4442]](https://github.com/plotly/plotly.py/pull/4442)
+- Fix issue with `FutureWarning` being displayed when setting the `color` argument in `plotly.express` [[#4519]](https://github.com/plotly/plotly.py/pull/4519)

MathJax is included by default in Jupyter-like environments, but when embedding Plotly figures in other contexts it may be required to ensure that MathJax is separately loaded, for example via a `<script>` tag pointing to a content-delivery network (CDN).

+##### Auto Tick Angle Options
+
+*New in 5.19*
+
+If `tickangle` is not explicitly set, its default value is `auto`, meaning if the label needs to be rotated to avoid labels overlapping, it will rotate by either 30 or 90 degrees. Using `autotickangles`, you can also specify a list of angles for `tickangle` to use. If `tickangle` is `auto` and you provide a list of angles to `autotickangles`, the label angle will be set to the first value in the list that prevents overlap. 
+
+```python
+import plotly.express as px
+df = px.data.gapminder()
+df = df.loc[(df.continent=="Asia") & (df.year==1992)]
+fig = px.histogram(df, x=df.country, y=df.gdpPercap)

+
+fig.show()

+
 #### Enumerated Ticks with Tickvals and Ticktext
 
 The `tickvals` and `ticktext` axis properties can be used together to display custom tick label text at custom locations along an axis. They should be set to lists of the same length where the `tickvals` list contains positions along the axis, and `ticktext` contains the strings that should be displayed at the corresponding positions.
