So, I don't think this was in the release notes, but either CFMX7 or 7.0.1 fixes a bug where a super call can't use named arguments. In other words, this used to throw an error:

As I said, this works fine now. However, if you try the same thing with a simple UDF copied to a structure, like the request scope, an error will occur:

Cannot invoke method ran on an object of type coldfusion.runtime.RequestScope with named arguments. Use ordered arguments instead.

I've filed a bug and hopefully this will be corrected.
