 - [ ] If this is a new minor version in the newest major version then run `./docs/governance/templates/release.sh {source version tag} latest`.
+- [ ] Once the images have successfully been pushed to the registry, modify the line `open-match.dev/open-match v0.0.0-dev` in all `go.mod` files in the [Tutorials] (https://github.com/googleforgames/open-match/tree/main/tutorials) directory to use the current release version. This includes all solution subdirectories as well
 - [ ] Use the files under the `build/release/` directory for the Open Match installation guide. Make sure the artifacts work as expected - these are the artifacts that will be published to the GCS bucket and used in our release assets.
 - [ ] Copy the files from `build/release/` generated from `make release` to the release draft you created.  You can drag and drop the files using the Github UI.
