The current separation looks good to me too.

I have a question related to issues to be included: we tend to normally not include backports in release notes. However, issues like [JDK-8299738](https://bugs.openjdk.org/browse/JDK-8299738) and [JDK-8335630](https://bugs.openjdk.org/browse/JDK-8335630) are included. Are these included because the backports were successfully made before the release of `jfx23`?
