v0.21.0 Release Recap
v0.21.0 is a non-breaking operations release that turns the snapshot and doctor pieces into a scheduled backup workflow. The new backup runbook documents export, restore preview, backup marker verification, launchd/systemd scheduling, and Norn drift pairing.
What's New
| Area | New in v0.21.0 | Why it matters |
|---|---|---|
| Backup runbook | Deployment: Backup Runbook | Gives operators one concrete daily flow instead of scattered commands |
| Restore preview gate | Dry-run import with --report before retention or promotion | Makes backup contents and node diffs visible before trust is placed in the file |
| Scheduler examples | launchd and systemd snippets | Makes the live Mini/Norn path and Linux deployments easier to automate |
| Norn pairing | Drift check next to doctor backup freshness | Separates service-discovery drift from backup-readiness evidence |
| Feature metadata | backup-runbook | Lets deployments advertise that the documented operational flow is part of the release surface |
Compatibility
This release only adds documentation and feature metadata. Runtime behavior, APIs, CLI flags, and storage formats are unchanged.
