+## Chip Component Changes
+
+The chip component's behavior has been updated to match the standard behavior of other components like buttons.
+Previously, the chip component would lose focus when the escape button was pressed. This issue has been resolved, and the chip component retains focus as expected.
+
+You can provide a custom `onKeyUp` handler to implement the previous behavior.
+
+```js
+import * as React from 'react';
+import Chip from '@mui/material/Chip';
+
+export default function ChipExample() {
+  const chipRef = React.useRef(null);
+  const keyUpHandler= (event) => {
+    if (event.key === 'Escape' && chipRef.current) {
+        chipRef.current.blur();
+      }
+  }
+  return (
+      <Chip label="Chip Outlined" variant="outlined" ref={chipRef}
+        onKeyUp={keyUpHandler}
+      />
+  );
+}
+```
