In a surprise and unannounced move from Just Flight, the company has elected to support their flagship X-Plane plugin Traffic Global during the Vulkan/Metal beta, version 11.50.

Sourced from Just Flight's support website, the changelog for v1.0.9113 which is for Windows and macOS versions of the addon, warns that the update had been tested against 11.50's first three betas, which were current at the time of updating. It also works with the current official version of X-Plane, v11.41r1.

Currently, we're sitting at beta 4 - Threshold has been unable to confirm that Traffic Global works with this beta version, though the changelog for beta 4 looks unlikely to affect the addon's functionality.

"Given that there are several more X-Plane beta releases planned it's just not possible to guarantee that this will continue to work while the platform it is running on is changing", said the developer in the "compatibility" section of the update log. "If something else gets broken in future X-Plane betas then another interim release like this one will be made as soon as possible."

A list of known issues is also available, the developer ensuring to stress that the TCAS system is completely non-functionaly. This is due to a "breaking change in the underlying simulator", meaning that nothing can be done to fix it at this time.

There's also a reported incompatibility with VATSIM's xPilot client, though only on "some" versions according to Just Flight.

With the major issues out of the way, here's the list provided for smaller problems:

• Transitions between certain go-around/circuit legs are not smooth.
• Airports with poorly-defined taxi routes may still use unnecessarily sharp corners.
• If you are using an external weather engine such as xEnviro, correct weather may not be set for a minute or so after the simulator starts. This will affect runway-in-use for aircraft initialised during this period.
• The custom map layers will re-enable themselves if you disable them, each time X-Plane loads new scenery. This is X-Plane bug XPD-10498 and can not be worked around.
• Custom views do not respond correctly in VR. This is X-Plane bug XPD-10412.
• If very few aircraft are nearby, additional false aircraft are reported via TCAS. This is X-Plane bug XPD-10434.
• Wind direction at airports can still cause the runway-in-use to change far too often with variable winds being fed to X-Plane from external weather systems. A fix for this is under development but is much more involved than it seems, and is not yet ready for release. Please bear with me!

Additionally, the following fixes are now underway - to be included in a later update:

• Further work on controlled changing of airport flows
• Enable multi-runway use on a wider range of badly-defined airports
• Significant changes in how pushback routes are calculated
• Several new datarefs
• Additional help for airport designers in the Flightplan view
• Aircraft may turn off the runway too fast for specific combinations of aircraft, runway, taxiway locations and flow
• Include all paints for all models for all known airlines, not just the ones used in the default traffic database
• Several paint fixes
• More efficient networking
• Field-of-view incorrectly affecting networked displays
• Aircraft continuing a reverse-pushback all the way to the first sharp junction

Lastly, the list of changes in the update. These are:

• Compatibility with both OpenGL and Vulkan/Metal modes.
• Fix for reading radio frequencies for certain airports.
• Additional logging around the pseudo-ATC. If the above fix doesn't help, please contact support with your log.
• Crash fix for random crash which was possible when TCAS was enabled and you changed aircraft mid-flight.
• Crash fix for a small number of third-party schedule files which referred to a specific set of airports.
• Crash fix for random crash when removing aircraft after the density setting had been reduced.
• Potential fix for certain commercial, third-party airports affecting calculation of AI touchdown points at airports at the end of long user flights.
• Wind direction is now calculated using the airport's elevation rather than the user's.
• Fix for a potential freeze during shutdown.
