API changes should automatically be detected by x/tools/internal/imports after each major release. After 1.14, they were manually updated as per https://github.com/golang/go/issues/38464. This should be part of the release process (maybe x/build/cmd/releasebot?).

@golang/release might have something to say about this.

As a first step, let's make this a recurring early-in-cycle release-blocking issue, similar to #40705 and #36905, so that this task isn't missed.
(If it's viable to automate this task so it doesn't need to be done by hand every 6 months, please file a new issue for doing that work.)
I'll place it in Go 1.17 milestone now, and when CL 293839 is submitted, it can be moved to Go 1.18.

Strictly speaking it would probably make it sense to do it shortly before the release, once the API has stabilized. But right after is fine too.
Comment From: dmitshur
@heschi Yep, that makes sense. The reason I've used this early-in-cycle path for now is the same reason I closed https://github.com/golang/go/issues/27155#issuecomment-779940755: we currently don't have a good system for tracking issues that aren't actionable until very late in a dev cycle. When we do, we can improve this task so it happens late in cycle instead.

This issue is currently labeled as early-in-cycle for Go 1.18. That time is now, so this is a friendly ping so the issue is looked at again.

CL 344629 updated the index for 1.17, so moving this to next milestone (with early-in-cycle) so this gets pinged when 1.18 is out.
Comment From: gopherbot
This issue is currently labeled as early-in-cycle for Go 1.19. That time is now, so a friendly reminder to look at it again.

I'll do this now. How do we feel about enforcing this with a test? And if we want to go that route, should the test start failing as soon as new APIs are added to the standard library, or once the standard library is released?

A better option for automation may be to create a release blocking bug associated with each major Go version.

This issue is currently labeled as early-in-cycle for Go 1.20. That time is now, so a friendly reminder to look at it again.
Comment From: findleyr
This was done for Go 1.20, so I bumped to the Go1.21 milestone.
Would be better to have separate issues but in the meantime I think this is set up for the next cycle.

Comment From: dmitshur
CL 464342 and CL 464875 regenerated the index after the Go 1.20 release. Moving to the next milestone since this won't need attention until Go 1.21 is out.
Note that relui will be generating these CLs automatically for future releases (implemented in #54377—thanks @dle8!), so it's not necessary to do it manually anymore.
Comment From: heschi
Seems like we can close the issue now that it's automated. No need to remind ourselves.
