My July 21 order has a January delivery date as of yesterday. Long range, Red/White, 20" wheels, 7 seats, no FSD, based in southern California. Started as Jan/Feb when I ordered, then January a week later (right around the first $5k price increase), stayed Jan until about labor day, blank for a few weeks and January just came back.
You can also now see your estimated delivery date in the app (at least on the latest iOS version). People on r/teslamotors also notice better, more accurate renders of their vehicles and other improvements.
