It includes the ruling on if Dash can elect not to use his ability when landing on obstacles (among other).
Keyan can (as we expected) remove Stress even if zero Eyes were rolled.
Also, if executing a zero maneuver when already touching now counts as still touching after the zero maneuver.
The maneuver from Stay on Target is ALWAYS red, even if changed due to a Navigator (or other means).
PtL and Experimentwl Interface "interrupts" other means to do actions that trigger them (e.g. Expert Handling) and can be used even if the triggering thing causes Stress.
And, if moving over both a debri field and an asteroid the opponent decides which obstacle you roll for.
