Server Queries with 1.10 and the new master server

So, I got questions with this new version/master server.

Are direct queries to the server itself the same as past versions/was anything removed/added/changed, was the RCON Protocol changed, and is the protocol used for the queries still the same? Also, what's the information for querying the new master server?

Nothing in the protocols was directly changed on the dedi's side. I'm pretty sure Btc22 implemented most, if not all, query protocols in the MS emulator

The only thing that really changed, w.r.t this, on the dedi side was the new MS domain (hosthpc.com, IIRC)
