This is the tracking issue for the Go 1.24 iteration of proposal #54265.

Hey, it looks like Go 1.24 branch is not created yet https://github.com/golang/go/branches/all. May I know what the next step is for this issue ^?

@smiletrl This issue is for the future. Right now we're working towards a Go 1.22.0 release. Nothing to do here until we get to the Go 1.24 dev cycle. There's more information at https://go.dev/s/release.

ah, I see. Thanks @dmitshur

This issue is currently labeled as early-in-cycle for Go 1.24.
That time is now, so a friendly reminder to look at it again.

There's an order we'll need to follow for this.

First, the builders need to be configured to start using Go 1.22 as the bootstrap. I'll be working on this part.
After that's done, cmd/dist and more code in the main Go repo can start to require it and take advantage of it (CC @aclements).

I'll likely target Go 1.22.6 (to be out soon) as the initial concrete bootstrap version.
