Version 3.8.0
February 22nd, 2026
- GSX Pro NEW: Animated stair operator — passenger stairs now have a dedicated operator who manually pushes and positions the vehicle, with full approach, departure and idle animations.
- GSX (all versions) NEW: Service termination — you can now terminate running services from the GSX menu by choosing "Complete now" (vehicles finish quickly) or "Abort" (immediate stop). This works for Boarding, Deboarding, Catering, Refueling, De-Icing, and Baggage services.
- GSX (all versions) NEW: Airport Handler Scripts — a new type of Handler customization that applies to a specific airport, regardless of which aircraft is being used. Airport handlers can dynamically adjust gate properties, display contextual messages, and react to the current flight plan, time of day, weather, and aircraft type. See the updated Manual for tutorials and examples.
- GSX (all versions) NEW: Handler scripts now have a hasStockBehavior() function to check whether the built-in handler has a real implementation for a given method, so scripts can decide whether calling the original method is needed.
- GSX Pro NEW: Added Seated Passengers support for the PMDG 737-600 and PMDG 737-900, recently released for MSFS 2024.
GSX Pro NEW: Added support for the Microsoft A330 Cargo variant.
- GSX Pro Change: When Seated Passengers are disabled, passengers will still walk through the cabin corridor to reach their seat position before disappearing, instead of vanishing at the door.
- GSX (all versions) Change: Vehicles leaving the gate now accelerate based on distance, matching the same speed scaling used during approach, so far-away vehicles don't crawl back slowly.
- GSX (all versions) Change: The Completing phase (vehicles driving away) now transitions to Completed as soon as all vehicles are disconnected from the aircraft and driving away, instead of waiting for them to reach their parking and despawn. This makes dependent services (e.g. Refueling waiting for Catering) proceed faster.
- GSX Pro Change: Passenger stairs now back away from the aircraft before lowering when detaching.
- GSX (all versions) Fix: Incorrect airline callsign recognition for livery-only aircraft addons that don't include their own aircraft.cfg file.
- GSX (all versions) Fix: Services staying in Completed state too briefly for third-party addons (e.g. Fenix) that poll the GSX state LVars. The Completed state now dwells for 10 seconds before returning to idle.
- GSX (all versions) Fix: "Free this parking from AI" now also removes default simulator ground vehicles in MSFS 2024, and AI airplanes are now removed in P3D as well.
- GSX (all versions) Fix: Multiple issues when performing multiple flight legs — fixed resource leaks in fuel truck, de-ice crane, stairs, pushback tug, and baggage loader that could cause incorrect behavior on second and subsequent legs.
- GSX (all versions) Fix: Cleaning service could get blocked after Deboarding if seated passengers were enabled.
- GSX Pro Fix: GPU was blocking the airport customization editor from opening.
- GSX Pro Fix: Stuck text on VDGS display panels that don't use scrolling (e.g. SafeDock TS24).
- GSX Pro Fix: VDGS font characters appearing underground at some airports with third-party scenery in MSFS.
- GSX Pro Fix: APIS VDGS static object not restored after gate was closed.
- GSX Pro Fix: RLG VDGS font objects were not cleaned up properly, causing a memory leak.
- GSX Pro Fix: Fuel counter position slightly off-center on the left-side fuel display.
- GSX (all versions) Fix: Potential crash when multiple vehicle movements were triggered at the same time on the same vehicle.
- GSX (all versions) Change: Faster passenger creation when boarding or deboarding starts.
- GSX (all versions) Fix: Potential crash in the walker animation when the walk distance is zero.
- GSX (FSX/P3D) Fix: Potential crash in the cargo loader when the bridge animation failed to initialize.
- GSX (all versions) Fix: Improved overall Couatl engine stability, addressing several edge cases that could occasionally cause unexpected exits during normal use.
- GSX (all versions) Fix: Rare condition where HTTP requests could stop working until the next restart.
- FSDT Installer Change: The installer now remembers the last active MSFS simulator between sessions, so you don't have to switch every time.
- FSDT Installer Change: Faster layout.json generation during installs and updates, particularly noticeable when reconfiguring Seated Passengers support on airplane packages containing lots of files.
- FSDT Installer Fix: Installer not detecting MSFS when the AppData folder is relocated to a different drive.
- FSDT Installer Fix: Broken symbolic links not detected after moving the installation folder, requiring a manual relink.
- FSDT Installer Fix: GSX Pro appearing as unlinked in MSFS 2024 when the GSX World 2020 child product was present.
