It is purely procedural. The old one was "informational", whereas the new one is "standards track". Since the IS-IS protocol is technically "owned" by ISO, any IETF work on IS-IS could only be informational. However, following an agreement with ISO, IP related IS-IS work can now become standards track. Hence the change of status, which required the issuance of a new
RFC.
Similar changes have been made to other IS-IS RFCs.
