And are there any major changes in the routine rules for calling back retired officers in this new document?

Yes, starting in March 2024, the Army has now given itself the authority to fill vacancies through retiree recall, so get ready:

THE RETIREE RECALL PROGRAM CAN BE AN EFFECTIVE TOOL TO FILL PERSONNEL SHORTAGES OF AUTHORIZED REGULAR ARMY VACANCIES THAT ARE CONSIDERED KEY AND ESSENTIAL.

Retired officers have always been liable to call back, even enlisted are if their initial enlistment doesn’t cover their much tinier window of obligation.

I said officers, but retirees are liable to recall and it isn’t new.

After 9/11 retired green berets were being sought at the time, I was under the impression they were being asked to come back rather than ordered, but there are many slots that doctors, dentists, scientists, experts in older systems etc. that can be needed during various situations.
