P-39 flight model update not released?

In the Air Superiority update the patchnotes said:
P-39 (all variants) — the flight model of this aircraft has been completely updated according to the current capabilities of the physical model. Polars of wings, fuselage, empennage, and propeller blades have been recalculated and corrected. Moments of inertia have been corrected.

However, no changes have been made yet, did the developers forget? The P-39 has one of the worst flight models in the entire game, it goes way back to the Il-2 Birds of Prey days, it is over 15 years old and urgently needs a rework. Can someone explain what happened to this “fm rework”, where is it?
