 ## [Unreleased]
+
+### Fixed
+- CI: `go test ./...` no longer fails on repos with no Go packages (added root `doc.go`).
+- CI: combined redundant double test run into single `-v -coverprofile` pass in `go.yml`.
+- CI: race job now uses `-short` to skip slow integration tests.
+- CI: lint workflow no longer does a full-history clone.
+- CI: pinned `golangci_lint_version` to `v2` and use `go_version_file` in `lint.yml`.
+- CI: benchmark workflow only installs `benchstat` when Go packages changed.
+- CI: require-changelog workflow no longer triggers on `edited` events nor clones full history.
