Damn, I was tired, launched the 15.09 instead of the next gcs
Okay, progress, now the battery voltage and current are correct on the osd, the disarmed warning disappears when I arm the quad,
but the battery low warning is still there even if the tresholds are set to 0 :/(edit: set the treshold in gcs instead of the osd config)
Also still can't change panels with a simple switch and rotation enabled. (edit: without the rotation option I have panel 1 and empty panel, not panel 1 and panel 2)
