+
+            There are a few manual steps remaining:
+              - [ ] Make sure you update the Golang version used in the previous and next release branches for the Upgrade/Downgrade tests.
+              - [ ] Build and Push the bootstrap images to Docker Hub, the bot cannot handle that.
+              - [ ] Update the `./.github/workflows/*.yml` files with the newer Golang version, the bot cannot handle that due to permissions.
+                - To accomplish this, run the following: `go run ./go/tools/go-upgrade/go-upgrade.go upgrade workflows --go-to=${{steps.detect-and-update.outputs.go-version}}`
