When will the firmware for the DM42 be updated?

[Thomas Okken]

• Better sign reversal detection in SOLVE
• New FUNC implementation, which protects the caller's RPN stack from operations like R↓ or CLST even in NSTK mode
• EDIT, EDITN, and INDEX now support editing lists, empty lists, nested lists, and matrices inside lists
• NN→S function: converts numbers to strings at full precision
  

There's more, but regardless, DM42 being at a Free42 version that is 16 months old is not great.
