The main substantive changes are the fourth board appointment and this paragraph: If ISOC further modifies [ISOC-By-Laws] concerning the number of IAB appointments to the ISOC Board or the timing thereof, the IAB will make reasonable modifications to the processes embodied in this document, without requiring further modification to this document. Such changes will be announced via an IAB statement. While this is certainly expedient, it's quite open-ended, entirely left up to the judgment of the sitting IAB about what "reasonable modifications" might mean. Certainly, with a by-law change that adds a board appointment, most anyone would consider it reasonable to just add that appointment with the appropriate periodicity, and it's reasonable not to have to rev this document for that. But 3677bis is now basically saying that BCP 77 is now obsolete, that this version is the last one and is indeed documenting current practice, and that future changes will be made by IAB decision and not by revision of BCP 77. Is that the intent? If so, maybe it would be better now to simply make BCP 77 obsolete and shift the whole thing into an IAB statement at this point. Barry
