What I want to know is, is Go still undergoing major revisions? I don't seem to have been able to find an answer to this, and it's annoying. I remember there being some fairly big changes some time ago -- not so recently now, but after it was already public -- and I want to know whether that's going to still be happening before I bother learning it.
There have been many changes to both the Go language and the stdlib, but it is really easy to keep your code updated (specially since gofix was introduced: http://blog.golang.org/2011/04/introducing-gofix.html ) so this should not be an obstacle to learning the language.
That said, version "1" of the language is due for early next year, which should provide a long-term stable language and set of libraries, for details see:
