 - Dashboard exposition tuning
 - Helm chart variables that shortcuts/expose static or dynamic Traefik configuration
 
+## Commit messages
+
+Commits messages should follow [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/) specification and should specify a scope.
+
+All commits will appear in traefik helm chart changelog with two exceptions:
+
+- CRDs: CRDs are shared between traefik and traefik-crds charts, thus, commits with this scope will appear in both charts changelog (e.g. `feat(CRDs): update Traefik proxy CRDs to v3.x`)
+- CRDs-.*: commits with `CRDs-` prefixed scope will appear only on traefik CRD changelog (e.g. `docs(CRDs-values: update values documentation`)
