For American Truck Simulator the Update 1.6 and for Euro Truck Simulator 2 the Update 1.27 has been released on Steam for Linux.

These updates add many new features like e.g. country specific police cars in ETS 2 and a windshield-mounted weigh station pass device in ATS.

Announcement of the Update 1.6 for ATS on Steam:

MAIN FEATURES

Weigh station pass device
The windshield-mounted box expands situational awareness for those who prefer to switch off all user interface elements for an immersive experience. It works the same way as the weigh station functionality which is a part of the on-screen Advisor "widget".

Trailer Liftable Axles
Differential Lock
Adaptive transmission modes (power, normal, eco)
Improved engine simulation model (friction, braking, consumption)

MINOR CHANGES

Air pressure simulation improved (pressure buildup, cut-off sound, application pressure).
Coin sound tweaked.
FOV range increased to 40-120 degrees in adjuster.
Engine brakes set to 3 positions (as most current trucks have). One-key-hold control will use full strength still.
If engine brake toggle input is not assigned, increase/decrease engine brake inputs work similar to retarder (in range from 0 to maximum).
Multiple fueling points on gas stations.
g_force_economy_reset flag is disabled after economy reset.
Transmission input shaft simulation (double clutch).

MODDING INFO

Single "overrides" (forced default) rule can be used instead of defaults-suitable rule pair across linked accessories.
All pressure units set consistently to bars (data, animation, dashboard UI).
Nominal air_tank_pressure value added to chassis data.
Changed interior animations: all air, oil and brake pressure (gauges, indicators).
New interior animation: trailer axle lift (indicator), differential lock (button, indicator).
New engine data: resistance_torque (measured at 2000rpm).
Coin sound made moddable in the same way as other sounds (through ogg file).
