Not sure if this matters, but the go/parser proposal for SkipObjectResolution is actually #46485, which is marked Likely Accept but not yet accepted. Per discussion we're OK either documenting it or removing it pending the final outcome of that proposal.

We are missing release notes for go/parser.SkipObjectResolution (proposal still pending) and net/http.AllowQuerySemicolons.

time: fix receiver for Time.IsDST method
b0355a3 
Only methods that modify the time take pointer receivers;
IsDST does not modify it and therefore should not.

For #42102 and #46688.

parser.SkipObjectResolution was documented in release notes in 1de3329, and http.AllowQuerySemicolons in 85a2e24.

As of now, there have been 2 updates to api/go1.17.txt since it was created (and this issue was based on):

  • In CL 326789, receiver for Time.IsDST method was changed from pointer to value, which was done intentionally by Russ for this issue (see comment above).

  • In CL 311129, a new RGBA64Image interface was added to image and image/draw packages. Relevant concrete types in image package were updated to implement the new interface. This corresponds to the accepted proposal image, image/draw: add interfaces for using RGBA64 directly #44808.

Remaining Work

  • Perhaps the image API changes are worth taking another look over, to confirm the implemented API matches the proposal (or deviates in ways that are intended and okay). I compared it in this comment.

  • CL 326790 has been reviewed with a minor comment, and just needs to be submitted. (CC @rsc.)

After that's done, there doesn't seem to be anything more left to audit for 1.17, so I think we can close the issue (but reopen if there are any more API changes that come up and need more work).

Thanks Russ!

Closing as done, to be reopened in the unlikely case there are new API additions that need to be reviewed for the eventual final release.

Not sure if this is important, but the heading text/template is missing in the issue description. The text/template changes now appear as though under the testing heading.

In case it's missed, reflect.Value.CanConvert (#47210) will be new API if a CL is merged.

Thanks, this is fine although the heading is missing.

In case it's missed, reflect.Value.CanConvert (#47210) will be new API if a CL is merged.

Thanks, the change that adds CanConvert includes a change to the API audit file (https://golang.org/cl/334669).
