+## `golang:<version>-tip`
+
+The term "tip" in the Go community is used to refer to the latest development branch ([a leftover convention from previously using `hg` for version control](https://github.com/golang/build/blob/6383021611af0e07cbf0a60222e066662557c796/cmd/coordinator/internal/legacydash/build.go#L313-L314)).
+
+These tags contains builds of Go's latest development branch, and they are updated on a ~weekly cadence.
