What did you do?

I published a v0.2.0 tag for three packages, each with a similar // Deprecated: comment in go.mod:

• https://pkg.go.dev/github.com/github/fakeca
• https://pkg.go.dev/github.com/github/certstore
• https://pkg.go.dev/github.com/github/ietf-cms

What did you expect to see?

All three show a ⚠ Deprecated message like this:

What did you see instead?

https://pkg.go.dev/github.com/github/fakeca doesn't show the message, but the other packages do.

https://pkg.go.dev/github.com/github/fakeca?tab=versions seems to know about v0.2.0 but it doesn't seem to be getting picked up as the "latest". https://pkg.go.dev/github.com/github/fakeca@v0.2.0 shows this, and clicking "Go to latest" takes you to v0.1.0:

The proxy has the right latest, so pkgsite seems to be behind.

go mod download -json github.com/github/fakeca@latest

	"Path": "github.com/github/fakeca",
	"Version": "v0.2.0",
	"Info": "/Users/filippo/pkg/mod/cache/download/github.com/github/fakeca/@v/v0.2.0.info",

This seems to have resolved itself by now. 🤔

(But as documented with screenshots, it definitely was an issue for a while!)

I'm running into a similar issue with the module github.com/nishanths/exhaustive. The latest tag at the time of writing is v0.7.9, which pkg.go.dev knows about in its versions page: https://pkg.go.dev/github.com/nishanths/exhaustive?tab=versions. However the v0.7.9 main page doesn't seem to think its version the latest. Instead the v0.7.8 main page seems to think its version is the latest.

(And just for completeness, nothing was deprecated in this module between the two versions.)

The command

go mod download -json github.com/nishanths/exhaustive@latest

finds v0.7.9 though.

I'm not sure exactly what happened there, but I do notice that v0.7.8, ...9, ...10 and ...1 were published within two hours of each other on November 11. It's possible that some out-of-order processing caused a temporary glitch, but it seems fine now: the latest page is v0.7.11, as it should be.
