We've just tagged a new Go release: go1.

Go 1 is a major release of Go that will be stable in the long term.
It is intended that programs written for Go 1 will continue to compile
and run correctly, unchanged, under future versions of Go 1.

The Go 1 release notes list the significant changes since the last
release and explain how to update your code:
http://golang.org/doc/go1.html

To learn about the future of Go 1, read the Go 1 compatibility document:
http://golang.org/doc/go1compat.html

Go 1 is available as binary distributions for the
FreeBSD, Linux, Mac OS X, and Windows operating systems.
To install a binary distribution, follow these instructions:
http://golang.org/doc/install

If you prefer to build from source, follow these instructions:
http://golang.org/doc/install/source

The Go team would like to thank all our contributors from the open
source community. We could not have done it without their help.
See the full list of contributors here: http://golang.org/CONTRIBUTORS

We also thank our users. We hope you enjoy Go 1.

Have fun. (And tell your friends! ;-)

Great news, thanks and congratulations!

I was hoping for a bit more PR around this release: "here's how we use
Go to great things!" "here's why Go is the best at what it does" and
so on. Will there be more videos like the ones that were released when
Go first was announced?

Blame hg, it should have deleted these directories. You have to delete src/cmd/{cov, prof},

src/pkg/{old,exp}, and then your build will succeed.

Although, I ran hg pull, then hg update release as opposed to go1. Otherwise, the output is the same.

This is indeed good news. I backed off using go due to "too much churn" and was waiting for this to climb back on. Now if goclipse will get updated to use go1, I'll be a very happy camper! :)

I hope I understood that document well. I will try to rephrase my question in other words: Are the point versions going to replace the weekly releases? If so, then everything's fine, I think/hope. If not *and* a bug gets fixed in the presumably longer interval between point releases - are they going to be backported to the previous release? Imagine a situation when someone hits a show stopper bug with his/her code using Go 1, fixed in some later weekly. Is such developer stuck, not being able to release, till the point release?

Sorry for not being clear enough in the first post.

Out of curiousity, why include "go" in the version numbers? The binary downloads are all go.go1.os-arch.ext. It seems a bit odd?! And annoying for a package maintainer like me. Thanks,

OK, on the one hand this could be seen as me not knowing Mercurial well
enough. On the other hand it shows that Mercurial tags are broken in
that the tag, when used, does not cause the appropriate change of
branch. Clearly this isn't a Go problem, except that it affects Go
bleeding edge users.

The Mercurial tags are working just fine.
In a rare event, minux was incorrect. You do not need to use
hg update release-branch.go1. Using hg update go1 is fine.

The 'clean.bash' in your original post failed because clean.bash
is only usable after you do a build now. A build with make.bash
or all.bash always starts from a clean slate anyway.

The 'all.bash' failed because your client had some stale binaries
in directories like src/cmd/cov, so the hg up, while it did delete
the tracked files, left the directories with the object dregs behind.
The build requires that those directories be gone, since they are
not part of the official Go 1. If you delete the directories that it
complains about by hand, all will be well.

These problems are primarily due to an impedance mismatch:
Mercurial is really a version control system and we're making it
work as a software distribution system. Most of the time they're
close enough not to care, but not always.

Sorry for the trouble.
Russ

Go was never officially "experimental". Go has Google's full and continued support.

You may be thinking of the Go AppEngine runtime that is still considered experimental, something we anticipate will change soon.

Thank you and the team for all of your work. I am trying to learn Go, but I've never mastered any language, only played around. The some of the concepts are difficult for me to absorb as presented in the documentation and tutorials. I've preordered the Go Programming book from Amazon, but do you know of any local Go Programming groups in the Denver area?
