Hello! The SP304 battery has been discontinued. Replacement for SP306. This battery is not suitable for the M3 programmer, you need to update the BIOS, but version v140107 is not suitable for this! Will Siemens have a BIOS update for the SP306 battery?

------------------------------------------------------------------------------------------
Split from How to update the Bios of the M3 PG?.

the latest M3 BIOS update supports SP305 only.

It seems Siemens will not support the M3 further and was end of life support in 2020.
