Forgive me for I’m not sure who wrote the code (and can’t look it up as I’m at work), but there was some code written last year to manipulate the eeprom. Is the code still good for this year? What I mean is have those locations in the eeprom deemed safe to write to last year still safe to write to this year?

For a definitive answer, I would post your question on the IFI forum. However, to the best of my recollection, all 1K of EEPROM is available to the user.

No change.
EEPROM works the same as last year.
