Additional context
Release notes

Note: Currently, the Does it ARM website lists EndNote X9. Clarivate (the developers) have since replaced this with EndNote 20 (similar to Office Releases). Not sure whether you wish to treat this as a separate product or not, if so I can create another issue specifically for X9 (runs via Rosetta).
