 - [#2260](https://github.com/plotly/dash/pull/2260) Experimental support for React 18. The default is still React v16.14.0, but to use React 18 you can either set the environment variable `REACT_VERSION=18.2.0` before running your app, or inside the app call `dash._dash_renderer._set_react_version("18.2.0")`. THIS FEATURE IS EXPERIMENTAL. It has not been tested with component suites outside the Dash core, and we may add or remove available React versions in any future release.
 - [#2414](https://github.com/plotly/dash/pull/2414) Add `dash.Patch`for partial update Output props without transferring the previous value in a State.
 - [#2414](https://github.com/plotly/dash/pull/2414) Add `allow_duplicate` to `Output` arguments allowing duplicate callbacks to target the same prop.
