deprecate this repo?

[zmstone]

Hi
I noticed that emqx-rel repo now has support for building packages.
Perhaps it's time to mark this repo deprecated ?
or if this has to be kept for old versions, we can at least add a link pointing to the right place for newer versions?

Hi, @zmstone
Yes, mark this repo deprecated is a good idea, but I don't know how to do it. Can you tell me?

Can just edit the intro title of the repo.
And also put a message to the head of README.
