ok, answered my question.
I reviewed the TSB from November. There are some fixes for 2023. The hardware identifier number is no surprise, some mentioned their version in the megasuperduper software thread.
anyway, I created a reference thread for firmware history, the Fixes are listed there, as are my other reference threads. I will update it as the 2020-2022 version so people will have a handy link for running the update/fix content.
This thread will have a better discussion about everything related to CP1.5 software.
TSB attached. Maybe someone will get the updated version before I do and throw it in the thread here. That would be nice.
ok- back to your 2023 software discussion.
