+## 5.0.1 (2022-04-12)
+
+Create React App 5.0.1 is a maintenance release that improves compatibility with React 18. We've also updated our templates to use `createRoot` and relaxed our check for older versions of Create React App.
+
+# Migrating from 5.0.0 to 5.0.1
+
+Inside any created project that has not been ejected, run:
+
+```
+npm install --save --save-exact react-scripts@5.0.1
+```
+
+or
+
+```
+yarn add --exact react-scripts@5.0.1
+```
