   Real free threaded support is a bit trickier than it seems.
   I adjusted fmod_toolkit just not to ship wheels that also get accepted by free threaded,
   but that just helps the install.

   For real free threaded support,
   all native extensions used by UnityPy would have to correctly implement some minimal API changes.
   Currently this isn't the case, which makes a free threaded python default back to the "normal" python gil behavior.

   Thanks for replying.
   While I acknowledge the technical hurdles of free-threading, enabling 3.14t support would allow UnityPy to finally leverage the full potential of modern CPUs through true parallelism.
