Guessing Added support for native MSFS 2024 airplanes installed locally (e.g. iniBuilds A300 2024 Premium update).
Yes, and no.
It more relates to the new kind of structure used by native 2024 planes, which is made of the airplane, the "presets" and the config files no longer in the airplane root, and the fact the airplane folder might be named differently so, even if the support is there, we still need to do extra step to make it work.
We are working on supporting the A350, so I can't promise the A300 will appear in the same update but if it's not, it will be shortly after.
