Where can I download Go v2? Latest is tagged 1.13beta1
Go authors stated multiple times that there are no plans for a Go 2 at the moment. They rather improve the language in small increments breaking as least as possible.
There are plans for Go 2[1], Russ Cox has written blog posts and given talks about design improvements for Go which would go into a Go 2. There isn't a roadmap (yet) but this discussion has been going on for the past year or so[2]. They talk a bit about next steps in the most recent blog post about Go 1.13[3].

But yes, the current Go 2 proposals are much nicer than the originals. But they do still contain some subtle breaking changes (though they have said they'd add vet warnings beforehand so it shouldn't be too bad).
