Holy Week was destroyed by Bugnini under Pius XII in 1955.
John XXIII inserted St. Joseph in to the Canon, removed the second Confiteor and some other changes I think. Someone else knows, I’m sure.
There are no "other changes I think". No need to be vague or exaggerate.
There were only 2 changes. St. Joseph was added to the Canon, and yes technically the 2nd Confiteor was removed, though in practice the SSPX and most 1962 users keep it in. I can't speak to what Indult and "approved by Rome" communities do in this regard.
Other than that, it is completely Tridentine. Nothing wrong with it, nothing to be criticized. Nothing weak, nothing defective.
