### Releasing during an active rollout
If you ship N+1 while N is still ramping, N+1 starts a fresh rollout from its own publish timestamp. N's rollout effectively ends — the newer manifest supersedes it.
If you ship N+1 while N is still ramping, N+1 starts a fresh rollout from its own publish timestamp. N's rollout effectively ends — the newer manifest supersedes it. Rollout-aware clients revalidate the manifest before installing a downloaded update on quit. If N+1 has replaced N but the client is not admitted to N+1 yet, it skips the downloaded N and waits rather than installing two updates in succession.
If N+1 is a hotfix for a bug in N, dispatch `desktop-rollout.yml -f tag=v0.1.<N+1> -f rollout_hours=0` after N+1 publishes so the users who already got N reach the fix fast.
### Limitations
- **No pause / kill switch.** Once a stable user is admitted, they will install the update on next quit (`autoInstallOnAppQuit = true`). To stop new admissions, ship a superseding release. To "recall" already-admitted users, ship a hotfix `+1` patch.
- **No pause / kill switch.** To stop new admissions, ship a superseding release. Clients revalidate on quit and will not install the superseded download, but a client that already completed installation cannot be recalled; ship a hotfix `+1` patch.
- **No rollback.** `allowDowngrade = false`. Bad release = ship a hotfix.
- **Bootstrap caveat.** Clients running a build older than the rollout feature ignore `rolloutHours` and admit immediately. Rollout protection only applies to clients running the rollout-aware version or later.
- **Up to ~30 min automatic admission latency.** Renderer polls every 30 minutes, so a stable user may take up to that long to be evaluated against the rollout window. Clicking **Check** is manual and bypasses rollout admission.
