My interpretation of "the rules have changed" line was Deaton saying that he changed sides and will no longer help Scott and his friends/pack. Like, he will help the bad guys instead.

I'm pretty sure Deaton has to follow certain rules since he's an Emissary. Even though he was an Emissary to the Hales, I do think of him as an Emissary to Scott's pack, as well. If there are some rules he has to follow when being an Emissary, they probably include stuff like "Protect the pack" or whatever. If "the rules have changed", maybe he's no longer allowed to protect Scott and his pack.

Also, when I say Emissaries may have "rules" I mean something similar to the Hunter's Code.
