Notable changes

This release includes one notable change.

1. Add top-level mediatypes folder (#27168)

Previously, support data for media formats was not available.

Now, a new top-level mediatypes folder has been created to host 11 image formats (mediatypes.image.*), and to support future data additions for other media types.
