## Versioning and Releases

The version is defined in the top-level `CMakeLists.txt` (`project(cppduals VERSION X.Y.Z ...)`). GitLab CI (`.gitlab-ci.yml`) handles tagging, packaging, and release creation automatically:

The version is defined in the top-level `CMakeLists.txt` (`project(cppduals VERSION X.Y.Z ...)`). GitLab CI (`.gitlab-ci.yml`) handles packaging and release creation automatically when a tag is pushed:

- **auto-tag** stage: when a commit lands on master, reads the version from `CMakeLists.txt` and creates a `vX.Y.Z` tag if it doesn't already exist

- **upload** stage: on tag push, creates a header-only tarball and publishes it to the GitLab package registry

- **release** stage: on tag push, creates a GitLab release linked to the package

- **upload** stage: creates a header-only tarball and publishes it to the GitLab package registry

- **release** stage: creates a GitLab release linked to the package

To cut a new release, just bump the version in `CMakeLists.txt` and merge to master — CI does the rest:

To cut a new release:

```bash

# 1. Update the VERSION in CMakeLists.txt

#    project(cppduals VERSION 0.7.1 ...)

# 2. Commit and merge to master — CI auto-tags and releases

git commit -am "Bump version to 0.7.1"

git push origin master

# 2. Commit the version bump and merge to master

# 3. Tag and push — CI does the rest

git tag v0.7.1

git push origin v0.7.1

```

**IMPORTANT:** After merging an MR that bumps the version, you must manually push a tag matching `vX.Y.Z` to trigger the release pipeline. The tag name must match the version in `CMakeLists.txt`.
