https://google.github.io/styleguide/go/ is the public version of it. Having read both I'd say the differences are small. The main thing missing, though, are the GoTip episodes that haven't been made public, and which are excellent.

I think the Google Go style guide is really nice and pragmatic. There are some references to the GoTips for some advanced subjects. I hope they release it someday.

I made an issue for it: https://github.com/google/styleguide/issues/881
