Same here. 2021.3.106.5 in Germany (M3 Performance, made in China). Never received an update and for some reason the release info for the software in my car is in french.
when I switch to English it’s in English and when I switch back to German it’s in french again. Very weird.
Other than that, they probably had to use alternative hardware due to the IC shortage nd are now working on merging the builds again.
They are already supporting many different hardware configurations in their main build so I think right now there is no real reason to expect 2021.3.10x cars to be permanently islanded.
Even if they were for some reason unable to merge the builds they could just roll the new features into the current build.
By the way, cars in Europe still have the radar sensor. Since we are also stuck on the same version as you guys, I don’t think it has anything to do with the vision only cars.
