 # [Versions](https://mui.com/versions/)
 
+## 6.3.0
+
+<!-- generated comparing v6.2.1..master -->
+
+_Dec 23, 2024_
+
+A big thanks to the 11 contributors who made this release possible. Here are some highlights ✨:
+
+- Fix invalid HTML structure in the Accordion component (#44408) @ZeeshanTamboli
+  The HTML elements of the Accordion summary have been updated:
+  - the root element is now button (previously div).
+  - summary content and the icon wrapper are now span (previously div).
+    This will only impact you if you used the HTML element as selectors in your styles.
