When is weather radar coming?

Clouds? It always showed (and still shows on SU10 Beta) precipitation, not clouds.

The weather radar is not enhanced (also that is not mentioned in the official changelog) so no turbulence or stuff like that.

The only thing changed is that the existing system now updates again on its own during flight. That was fixed alongside with the implementation of the new API I guess.
