# 08 Versioning

Streetline Heroes uses simple asset version milestones.

| Version | Meaning |
| --- | --- |
| v0.1 | Concept |
| v0.5 | Review |
| v0.9 | QA |
| v1.0 | Approved |

## Rules

- Version numbers belong to asset packages, not only files.
- `v1.0` requires approval.
- Any visual change after approval creates a new version.
- Deprecated versions move to archive with replacement notes.
