The File object now stores width and height of files that can supply this kind of information. Formats which we can not read natively in PHP do not currently benefit from this. However an event hook will be introduced later. The CreateFileImageThumbnail event is renamed to: CreateFileImageThumbnailSource to clarify that the hooks should not generate their own thumbnails but only the source image. Also it now accepts File objects, not MediaFile objects. The thumbnail generation is documented in the source code. For developers, call 'getThumbnail' on a File object and hope for the best. Default thumbnail sizes have increased to be more appealing.
