Traction control is gone, all teams are using a 'controlled' ECU where tc can't be hidden in software now. Launch control is also gone. As far as I know driver releases own clutch and determines revs via way of the old fashioned right foot.
I'm 99.9% sure that auto shift is gone too and they're back to semi auto where the driver has to at least shift up/down and they might have pre programmed gear selectors for certain corners like they had 3-4 years ago.
Aero regulations have been changed this year to make passing 'easier'.... a car following another closely will supposedly no longer have such an aero disadvantage because the car in front isn't going to be disturbing the air as much as before making their front/rear wings still work to a certain degree. Should allow for cars to follow each other more closely
Tyres are full slick again, but this is kind of pointless because they've been made narrower. Tyre surface area is probably the same as when they were using grooved tyres.

Totally agree about Webber, I'm really surprised he still has had a seat in F1 for this long already! He's a complete knob
