The "MARC 21 encoding to accommodate new RDA elements 046 and 3XX in NARs and SARs" cheat-sheet listed on NACO's landing page saw a slight update on August 1. The only change I came across is the "Notes" area for the 373 field. Previously, separate comments were made on personal name and corporate body name application; these are done away with in the current iteration.
