In a deal that is currently still under negotiation, Aston Martin would become brand partner with four-time world champion team Red Bull Racing in exchange for brokering a deal for it to run the dominant Mercedes F1 engine.
Under the deal Mercedes would be recognised as the official engine supplier of Red Bull, but Aston Martin would become a partner and have branding on the cars.
The deal is said to have the blessing of Mercedes...

So, Red Bull to (maybe) dump Renault and run with Mercedes engines next year unless I've majorly misread that.
