Does anyone know if the new batches of pics, specifically the 18F452 and it's relatives, still have the errata where you have to insert 0xFFFF as the first instruction in the subroutine?

I noticed that CCS mentions it took out the 0xFFFF errata patch.

Beginning with the B5 errata sheet, Microchip no longer mentions
that particular bug.

Thanks for pointing that out. I asked a local FAE and he told me that he wasn't told if that problem was fixed. I'll be sure to relay the info over.
