Yes, relax supports ColdBox 4.0 now. Here is the ticket to add that support:
The old Wiki documentation is for the 3.x version of ColdBox so it probably won't get updated. I don't know if Luis has created a "new" location for the Relax docs yet. We're still transitioning everything over to GitBooks and the Relax module falls in a weird group of modules that aren't part of any of the core frameworks so we're not sure where to put the docs.
The last time Luis and I talked about it we discussed just using the GitHub wikis for these smaller libraries, which would be located here:
Obviously, nothing has been added yet for Relax so I guess as they say, "watch this space" :)
Thanks!
