> 5: The fix for [JDK-8340852](https://bugs.openjdk.org/browse/JDK-8340852) changed the behavior of `ScrollPane`. With the latest update, `ScrollPane` only responds to keyboard navigation when it is the focused node. If you prefer the previous behavior, where `ScrollPane` always reacts to arrow keys and other navigational inputs, you can manually restore it by adding an event handler:

Suggestion:

Adding this event handler will make `ScrollPane` react to navigation keys as it did before the update.

> 68: JavaFX 24 supports the Java Image I/O API, allowing applications to use third-party image loaders in addition to the built-in image loaders. This includes the ability to use variable-density image loaders for formats like SVG. When an image is loaded using a variable-density image loader, JavaFX rasterizes the image with the screen's DPI scaling.

"Refer to the Java Image I/O documentation for more information."

Perhaps give a link to the Image I/O documentation?

Should we give a link to https://openjfx.io/javadoc/24/new-list.html to easily see new API (when the docs are published)? Maybe even to https://openjfx.io/javadoc/24/deprecated-list.html.

I'm not sure it's beneficial to include obsolete version updates. If the final update of a dependency is to 1.2.3, then any previous update (1.2.1) doesn't need to be listed, in my opinion.
