Downloaded and installed, not really a lot diffence between Marshmellow and Nougat, only thing missing is Turbo Download, to use 3G and Wifi, why is it missing?

Guys, i want to wait, to be safe that i have no heavy issues in the rom, but what should i say... i cant wait and already installed it. And i cant say anythin bad until now... In this Version its google certified! It reacts quick and when i charge it its faster than android 6. When i restart/start ...

Hi all
Am I stupid or something, when I open the link it says "The file you are trying to download is no longer available"
