Releasing a new Version

Semantic Versioning

The UMH uses the semantic versioning. This article explains how to increase the version number and what steps are needed to take.

Steps

1. To create a release branch, use the version number as the branch name. For example, if the version is 0.6.0, the branch name should be 0.6.0.

   For pre-releases, use the version number with a -prerelease suffix as the branch name. For example, if the version is a pre-release of 0.6.0, the branch name should be 0.6.0-prerelease.

2. GitHub Actions automatically builds Docker, using the branch name as tag.

3. Create a pull request from the release branch to main.

4. Update the helm chart united-manufacturing-hub by opening Charts.yaml and changing the version to the next version (including a prerelease if applicable).

5. To adjust the repo link https://repo.umh.app in docs/static/examples/development.yaml, change it to the deploy-preview of helm-repo. For example, change it to https://0.6.0.united-manufacturing-hub.pages.dev. Additionally, add a --devel flag to the helm install commands so that helm considers the pre-release as a valid version.

6. Navigate to the folder deployment/helm-repo and run the following commands:

   helm package ../united-manufacturing-hub/
   helm repo index --url https://<version>.united-manufacturing-hub.pages.dev --merge index.yaml .
   

7. Make a commit and push the changes.

8. Wait for all container and deploy previews to be created.

9. Perform all tests.

10. Repeat steps 4 - 6 with the changed version number 0.6.0 (instead of 0.6.0-prerelease) and the changed repo index URL: https://repo.umh.app.

11. Remove pre-release helm packages from the repository.

12. Make a commit and push the changes.

13. Merge the pull request from the staging branch to the main branch.

14. Create a new release that contains a changelog of all changes. Use the GitHub feature to generate the changelogs and create a new section at the top for release highlights.
