Please do not run 'hg submit' - even after Go 1.2 is released - until there has been an update to this thread saying it's okay.
Go 1.2 is of course very close. Andrew (adg) is running the release, and he should be the only one running 'hg submit' for that.
After Go 1.2 is out, work on Go 1.3 begins. As discussed in the thread Rob started ("Planning the next release"), there are some large changes planned, among them precise scanning of goroutine stacks during garbage collection and the new growing contiguous stacks. There are a handful of reviewed CLs by cshapiro and khr to lay the groundwork for these changes, and we'd like to get them in and happy on the build dashboard before we open the tree to other changes. Once those CLs are in, I expect we will mostly open the tree for changes but still keep the runtime, compilers, and linkers locked a bit longer.
We'll reply to this thread with updates.
Thanks very much.
