doc-files/release-notes-24.md line 70:

> 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.
> 69: 
> 70: Applications that want to use this feature can use existing open-source Image I/O extension libraries, or register a custom Image I/O service provider instance with the `IIORegistry` class. Refer to the Java [Image I/O documentation](https://docs.oracle.com/en/java/javase/23/docs/api/java.desktop/javax/imageio/package-summary.html) for more information.

NOTE to reviewers: I will change this to 24 with the next commit, but since it will be transiently broken, I wanted to give reviewers a chance to see the page with working links.

I'll change this from 23 to 24 in the next commit.
