LR 12.3 added support for file formats JPEGXL (JXL) and AVIF but forgot some things:
- The smart-collection criterion File Type is missing JXL and AVIF as values.
- The Metadata panel's File Type field is blank for JXL and AVIF photos.
The Metadata browser's File Type column does show JXL and AVIF. (And in case you're wondering, HIF files show up as file type HEIC in all these places.)
