That's truly annoying, as I have a model based on March 2020 revision. Then I noted changes from November 2020, which were already quite different, and now from February 2021... these one are quite drastic changes. Finally specified plank with longer diffuser and updates on floor channels will change a lot, some changes apply to both front and rear wing with complete rework on DRS system rules.
Just imagine that teams are allowed to work on 2022 cars from January this year under strict budget caps, working for 2 months and then FIA out of nowhere changes rules so much, that it's basically B-Spec car.
