Some languages like Erlang have TCO. Is it the case with Go as well?
Specifically, I mean the main (popular for now) compiler available here: http://golang.org/doc/install
There are no such plans for gc (6g, 5g, 8g).
I think it's very unlikely that the language would require it.

In the unlikely event that this changes, it will be documented in the Go Release History.
