RFCs Tracked
About this page: Tracks which RFCs in the library obsolete or update other RFCs. An OBSOLETES relationship means the newer RFC entirely replaces the older one. An UPDATES relationship means the newer RFC modifies or extends the older one without replacing it. Entries link to detail pages where available in this library.
