Activated work gas for (p)scr mode: In previous version setting of change depth for work (travel) gases was not possible. For (p)scr operation this is not possible. Work gases will not be considered for deco calculation. In addition the first gas will be handled as "deco" gas. This allows switching back to the first gas in case the current gas becomes no longer breathable (ppo2 low).
