Releases and lifecycle
Version identities answer different questions. Keep them separate so a source change, released artifact, supported product combination, deployed instance, and documentation revision do not become one ambiguous “version.”
Version layers
| Layer | Identifies | Evidence owner |
|---|---|---|
| Source revision | An immutable repository state | Public component repository |
| Component release | A published artifact and its release notes, provenance, tests, and compatibility | Component release record |
| Product release | A verified set of product-owned components and public support contract, when published | Product owner |
| Deployment version | The exact approved component and configuration identities in one environment | Authorized environment record |
| Documentation version | The reviewed revision and status of a page or site release | Documentation repository |
Code presence does not prove release, deployment, support, or runtime implementation. A component release does not prove a product combination, and this page's document version does not version product software.
Select and promote a release
- Resolve the public source and immutable release identity.
- Review release notes, dependencies, compatibility, security changes, deprecations, licenses, and release evidence.
- Verify provenance and artifact identity when available.
- Test the exact artifact and intended version combination.
- Update architecture, security, operations, backup, recovery, observation, and retirement documentation where affected.
- Approve and promote through the environment's controlled stages.
- Independently verify the deployed outcome and retain classified evidence.
Public component release pages
- ModuLix automation releases
- ModuLix launcher releases
- Foundational collection releases

- Ubuntu collection releases
- OpenShift collection releases
- Supplementary collection releases
The lists are discovery points, not a statement that the latest release is approved for a deployment.
Documentation lifecycle
Pages are maintained, deprecated, or retired based on verified public behavior. Review after a relevant release, architecture or security change, incident, standard update, or at the metadata cadence. Preserve redirects only for stable previously published paths, avoid redirect chains, and never retain obsolete claims merely for link continuity.
See the ModuLix lifecycle for automation-content decisions.
