Couatl™ Live update release notes

Version 4.0.22 – September 11th, 2026

• GSX (all versions) NEW: New gate profile option externaljetways = 1 for stands whose jetways are driven by third-party tech GSX cannot detect (such as iniBuilds KORD): boarding and deboarding run simulated at the jetway, without visible passengers, instead of falling back to stairs and bus.

• GSX (all versions) Fix: "Complete now" while cargo was still being moved made the loader count the unfinished trip as done and call for another train; it now just packs up.

• GSX (all versions) Fix: A vehicle leaving on a custom path whose first point sat just behind it drove a tight full loop through its own position before setting off - a baggage train doing this appeared to spin on itself.

• GSX Pro Fix: The cargo staircase platform stopped up to 20 cm above the door at mid-range door heights; it now stops at the door, and all staircases account for the apron slope between the airplane and the stairs.

• GSX (all versions) Fix: Several issues that could make ground vehicles either wait on each other forever or ignore each other while moving.

• GSX Pro Fix: In MSFS 2020, the keyboard hotkey could stay inactive for the whole session after a cold start of the simulator, until Couatl was restarted.

• GSX (all versions) Fix: A departing baggage train blocked by another vehicle now drives around it, instead of asking to remove passenger stairs it only needed to drive past.
