I've got the same report. Had the update done yesterday. Motoring thru traffic is now smooth as silk. I couldn't believe it. Ther were 2 components to the upgrade. The 1st took 27minutes. The 2nd about 20minutes. There was a brief email that the tech had to refer to tore-enable the windscreen control. My bike was the 1st he had done, and even with that, he had no problems. Coming home via the slab, I didn't notice any change in power or acceleration, fwiw.
My advice, go for it.
