I had purchased two extra boards to play with and did put in the firmware change to the one of them. It refused to work after that, so I may have done something wrong (It did work before) . The board did say v1.3 but no motor running at all. The yellow light is on and it recognizes the usb but that's it. I then put 1.4 back in and still nothing.
So I tried the second board and it did take the change. The default PID really did act differently because the motor would not stabilize. I am pretty sure the pid settings could have been adjusted to help stop the oscillations.
As much as I would love to have the decelerate I am concerned with taking out any more boards and really would be great if the firmware didn't loose the current and speed limiting.
If there was a compromise firmware that just made acc/decel to be the same value that would make a lot of difference and I wouldn't think it would be that much of a change to have to remove the current limiting. So if you have a wish list put it on there.
I really do like these little controllers but for that one missing piece.
I will play with the PID with the rest of the boards I have using v1.4 to see if I can take out the overshoot that way.
