Firmware V30 has been released for DM1x and DM41 units.
All models
A new serial console command has been added that allows software to place the calculator into bootloader mode via the serial port, which in turn will pave the way for a new updater that can preserve the calculator's memory and won't ask you to poke paperclips into the back of the machine.
Because of the increasing number of features going into these calculators we have had to drop support for early DM1x/DM1xL models based on the LPC1114 chip with a flash ROM of only 32kB. There simply isn't room in there for all of the features now.
There are a few cosmetic changes to the emulator's status screens and the calculator emits a reassuring beep when it boots after a reset.
DM41/DM41L
Some improvements in the Nut CPU emulation layer driven by development of the DM41X have been backported to the DM41(L).
Bugs in the handling of a stopwatch countdown timer alarm have been fixed.

Remember, folks, that a firmware update on a DM1x results in "Pr Error" on the display. This does not indicate a failure, it is normal behaviour!
