CC @rsc, @ianlancetaylor, @FiloSottile, @mknyszek, @mpvl, @golang/release.

toothrot · 2021-01-07T19:18:02Z

Hello @rsc, @ianlancetaylor, @FiloSottile, @mknyszek, @mpvl, @golang/release. Could you please verify and check-off these changes?

dmitshur · 2021-01-21T22:02:46Z

Most of the remaining items are related to go:embed and the new io/fs package. @rsc Can you please take a look? Thanks.

@mpvl Do the Unicode API additions look okay to you?

ianlancetaylor · 2021-01-22T23:33:12Z

I've gone through all of these, and verify that they look OK, and that they are mentioned in the release notes. I think we are good.

dmitshur · 2021-01-27T19:50:56Z

There are a couple API additions since api/go1.16.txt was created and this issue filed, as reported by the API check now:

go/build/constraint is a new package in Go 1.16, added in CL 240604, and it's a part of an accepted proposal #41184. @rsc Please confirm the Go 1.16 API looks right or if something is unexpected.

x509.CertificateRequest.KeyUsage needs to be looked at. Perhaps it should've been rolled back in https://golang.org/cl/281235 but got missed. @rolandshoemaker Can you take a look please?

I'm not sure why we didn't notice these earlier via a failing test or some other mechanism. I'll investigate that. CC @toothrot. Update: See #43407 (comment).

rolandshoemaker · 2021-01-27T19:56:58Z

Ah yup, looks like we missed it. I'll open a CL to revert the last bit.

dmitshur · 2021-01-27T20:03:49Z

Thanks Roland.

This was caught in the RC1 release tests, so we do have a mechanism, but it can be improved to help detect this earlier in the future. Filed #43956 about that.
