Developer snapshot 2026-06-19

Automated developer snapshot of the dev branch, for players who want the newest features before the next stable release. Expect rough edges; your save files stay compatible whenever possible, but back them up first.

Changes since the previous snapshot

Added

• Contextual route and weather audio. Driving now uses in-cab rain, snow, wind, fog horn, and thunder cues plus short route-event sounds for hazards, construction zones, inspections, tolls, state crossings, rest stops, weigh stations, facility gates, and docking. The road bed is back in the mix so the cab does not feel dry while moving. The experimental vehicle engine sound redesign is not included yet because playtesting exposed issues that need a separate pass.
• Route rest, toll, and settlement realism. Route planning now uses richer checked-in stop coverage, supports shoulder-sleep edge cases, accounts for toll and settlement details more explicitly, and keeps those systems covered by focused route, hours-of-service, weather, world-data, and settlement tests.
• Air-brake startup and reservoir behavior. Trucks now build air pressure before departure, keep spring brakes engaged until the system is ready, and model service and emergency reservoir pressure while driving so braking feels more like a heavy truck without stranding new careers.
• Driving status menu. Pressing Tab while driving now opens a spoken status menu with load, trip, truck, route, and route-stop details from the road.

Changed

• How-to-play driving guidance. The main-menu guidance for driving controls is shorter and more direct, with the spoken tests updated around the simpler wording.

Fixed

• Pickup facility sounds. Pickup gates and loading now use the new facility ambience and dock cues instead of the older generic menu notification sounds.
