YANG Catalog doesn't report the latest revision of iana-if-type module. Currently it has 2017-01-19, even though IANA already has revision 2019-07-16:
https://www.iana.org/assignments/iana-if-type/iana-if-type.xhtml
Possibly it could be the case for other modules that mirror IANA registries.
I would suggest to implement automatic checks of IANA pages such as the one above.
