No, Gerard. What I meant was that Montenegrin wasn't listed in the 2017 SIL approval process because it came to SIL through the ISO 639-2 process, not through a standard ISO 639-3 change request. But SIL most definitely has approved the code as an ISO 639-3. See http://www-01.sil.org/iso639-3/documentation.asp?id=cnr.
