+// Do not pin patch version here. Leave patch at X.Y.0
+// Unset GOTOOLCHAIN to assume GOTOOLCHAIN=local where go cli version in path is used.
+// Use env GOTOOLCHAIN=auto to allow go to decide whichever is newer from go.mod or cli in path.
+// or GOTOOLCHAIN=goX.Y.Z to use a specific toolchain version
+// See: https://go.dev/doc/toolchain#select and https://github.com/vmware-tanzu/velero/issues/8397
