incorrect call sequence for `f(0)`. New in this release is a better detector for
this error condition when the incompatible declarations appear in different
files. See [#67699](/issue/67699).

### Vet

The new `tests` analyzer reports common mistakes in declarations of
tests, fuzzers, benchmarks, and examples in test packages, such as
malformed names, incorrect signatures, or examples that document

  - type: input
    id: go-toolchain
    attributes:
      label: Changes to Go ToolChain
      description: "How many tools (such as vet, gopls, gofmt, goimports, etc.) would be affected? "
    validations:
      required: false

  - type: input
    id: perf-costs
    attributes:
      label: Performance Costs

When testing a package, `//go:debug` lines in the `*_test.go`
files are treated as directives for the test's main package.
In any other context, `//go:debug` lines are ignored by the toolchain;
`go` `vet` reports such lines as misplaced.
