+# shiny.react 0.4.0
+
+- Upgrade React to 18.3.1:
+  - Replace deprecated React API. React 18 deprecates (React 19 removes) `ReactDOM.render` and `ReactDOM.unmountComponentAtNode`. `ReactDOM.createRoot` is used in place of those functions according to the [React 19 migration guide](https://react.dev/blog/2024/04/25/react-19-upgrade-guide#removed-deprecated-react-dom-apis).
+  - Changed rendering mechanism of React components. This change is motivated by the fact that it's impossible to call `ReactDOM.createRoot` on a container more than one time while `ReactDOM.render` allowed that. A `data-react-id` attribute is used to find and render React roots in place iterating over all nodes with `.react-data` class.
+
 # shiny.react 0.3.0
 
 1. Render React asynchronously and only once Shiny is fully initialized:

+## Author comment
+
+Submission of this version of the package breaks shiny.fluent and shiny.blueprint packages which depend on shiny.react due to the React upgrade.
+
+The submission of shiny.react 0.4.0 will be followed by a submissions of shiny.fluent and shiny.blueprint, which will address compatibility issues.
