| Branch | Role | What targets it |
|---|---|---|
| **`main`** | Active development. The next release is being assembled here. | Feature PRs. Most bugfix PRs. |
| **`stable`** | Curated release channel. Production-recommended. | Urgent bugfix backports only — small, surgical PRs that land cleanly without dragging in unrelated changes. |
| **`stable`** | Curated release channel. Production-recommended. | Security fixes and regular bugfix backports, kept small and free of unrelated features. |
### Which branch should my PR target?
- **New feature** → target `main`.
- **Bugfix that ONLY affects active dev** → target `main`.
- **Bugfix that current stable users need** → open a small PR against `main`, AND a separate small PR against `stable` with the same change. Keep both surgical so each lands cleanly.
- **Bugfix that current stable users need** → target `main`; regular bug fixes are generally backported automatically to `stable`. Maintainers handle conflicts or create a separate focused backport PR when needed.
- **Security vulnerability** → report privately using [SECURITY.md](SECURITY.md). Security fixes are always released on both `stable` and `main`; coordinate any fix with the maintainers before opening a public PR.
**Hard rule on PR scope**: bugfix PRs against `stable` must be small enough to backport without conflict. Omnibus PRs (e.g. five unrelated sub-features) are fine for `main`, but never for `stable` — they make the next `main → stable` merge painful and break the "stable is always shippable" invariant.
