Disclaimer: I am not asking for help; I am sharing my experiences. Installed sugar-0.84.17 in a couple of F11 XO-1s. It seemed to me that recognizing the presence of other XOs on the mesh (channel 1) was quicker and more reliable than what I had previously gotten used to. [Mesh has sugar-0.82 XO1s, sugar 0.84 XO1s, and sugar-0.88 XO1s.] mikus
