Pennzoil MS-12633 No longer?

[Ram Vendetta]

Case of Pennzoil 0w-40 ultra platinum full synthetic just delivered, however on the back there is no longer the “Meets or exceeds Chrysler MS-12633.” Now rear of bottle states meets or exceeds Chrysler MS-A0921 Is this compatible if known? The bottles are dated Jan,27,2021 so don’t want to hear it’s an old batch.

It’s still listed on the Pennzoil website as meeting the MS-12633 spec, for what it’s worth.....
