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

Big thanks Umberto

Looks like a great update with lots of new and important features. With so much being covered for the tubliners, it would be nice to see a GSX for small a/c for charter ops.

Stretched golf carts, limos, SUVs for pax. Hand push carts, side by sides for luggage. Optional attire for pilot from formal to relaxed attire. Marshaller for engine start and departing taxi from parking.

I'm confused, I thought the A330 P2F was already supported.

Shame no update on the PMDG 777

Great Update.  I love GSX

Just installed it, rebooted, launched MSFS 2024, and when outside of the IF MAX 8 requested Stairs which is something I always do at a ramp at KPDX...whereupon suddenly I was up over water, external view, then the plane just dropped down to tarmac.  I couldn't believe it happened to rebooted and tried again and same thing only the plane was now upside down on tarmac.  Despite the fact the update appeared to go normally that is what happened.  Weird!

 

Here's a video of this.  When in external view looking at the plane after just hitting ready to start teh flight, pull down the GSX menu and hit Operate Stairs at which point I'm taken where this video displays, over a body of water.  In the video I pull down the GSX menu again and now I am offer a service brand to choose.  I do that, and nothing happens, still sitting over water.  Next, I had Shift-C to go into the cockpit and the video displays what happens next.  Weird!

Any way to roll back to the prior version?  This is heinous!

Same is happening to me but with pmdg 737-800, just after I updated to this new version, it seriously f up something.

I just tried Fenix and same same, except I didn't even need to hit Operate Stairs it just took me over the ocean again.   Someone just posted about if on their forum, and I posted the video in the thread.  Hopefully Umberto will see it quickly as GSX is now unusable in 2024.

Of course I already replied on the forum (which is the first place you should go to report anything), and I asked if it happens only if you have the "auto-reposition" option enabled, which is the only thing I can think can possibly cause this.

 

Thank you to everyone who is sacrificing their Sunday simming to test this new GSX update.

Yes, thank you to the early adopters who updated.. I think I'll wait a few months before hitting update.

Exactly what PMDG 777 update are you looking for?

I've only used the A330 so far, but I've had no issue with auto-positioning, yet.

I believe Umberto did some code revision because now rerunning the update fixes the issue it appears.  I say this because I already had rerun the update to no avail, immediately after the initial problem was identified.  In any case it's working fine now after hitting the Check button in the installer to rerun the update.
