CL 561935 - crypto CL that used purego tag and mentioned accepted-but-not-implemented proposal https://go.dev/issue/23172 to document purego tag; doesn't need a release note
CL 568340 - fixed a spurious race in time.Ticker.Reset (added via accepted proposal https://go.dev/issue/33184), doesn't seem to need a release note
