Ok, so quick TLDR from what I got via google translate:
- Massa drove 20 aggressive laps on softs without too much problems
- time gap from medium to soft compound can be up to 2s for some cars, feels like a different car after switch
- tires heat up slower, but not too slowly, able to do 2-3 quali laps as result
- if tires do overheat, they're back to normal within a few corners
- pressures lowered to 22psi front, 18 rear (not sure what was used last year atm) with possible further reduction upon data evaluation by pirelli
- degradation from 20 laps on softs is around 1.5s (down from 4-5s last year)
- Tires now work in a wider temperature operating window (helps ferrari)
- less marbles overall
- a lot less pit stops predicted
- Pirelli say they brought tires as were requested (less degradation), but are willing to go back to more degrading tires in 2018 if requested so
- Massa says dirty air is more noticeable
