I just ran the 1.61 beta software...
Did not test it yet (actually I tested the "older" 100422 just yesterday on my bike with the Xerun 60A and Nosram 13.5T, see the HW Xerun thread).
so, the 1.61 contains three sw's: V1.10 205 mod, V2.0 422 stock and V1.10 323a_m
I installed the 422 stock to my 1/5 bike, and for the first time the "Apply" button is not greyed, and it didn't ask me to "upgrade software".
I may have some time to test it later today.
I took some screenshots...
Also note that the LCD Program Box now says V1.05_100420 on the initial screen.
