If you mean 2024.14.3, TeslaFi currently shows about 450 deployments, but that’s only to vehicles that use TeslaFi. If 2024.14.3 has FSD v11, which isn’t documented yet, it won’t go to cars that have 2024.3.x because they already have FSD v12.
We now know that 2024.14.x has FSD v12, so you should be able to get it regardless of which build you have now (assuming you have the hardware required for FSD v12). However, I haven’t received it yet on either of our cars (both on 2024.3.25 currently).
