No, nothing new, same September 2021 one but the Enablement Packages msu files are only available with WSUS releases, hence the links
Thanks for clarification. Actually WSUS has 2 distinct releases, September 2021 and November 2021 which internally are the same, but there must be metadata differences, signatures etc.
I actually ment EP KB5003791 file from September WSUS releases are not the same September is 19044.1165 (old KB5003791, created in June) November is 19044.1288 (new KB5003791, created in September)
It will probably get cleaned up later. It's not like your phone's alarm clock won't go off in the morning because of this one update you duplicated.
