v0.0.15 — the memory card becomes a rescue disk, and the panel gets its look

Released 2026-07-21.

Highlights

• After migrating a Raspberry Pi’s system to an SSD, its memory card becomes a rescue disk instead of being left unused. If the SSD is ever removed or stops working, re-inserting a bootable memory card and power-cycling the node now boots it, even in cases that previously needed physically opening up the machine to recover. Retiring the memory card at the end of a migration now walks through the physical steps clearly: power off, remove the card, power on.
• The panel gets a real, distinct visual design instead of default off-the-shelf styling, with an accessibility pass alongside it: bigger touch targets on phones and tablets, loading placeholders so a page that’s still fetching data never looks empty, and clearer keyboard navigation throughout.
• The panel loads faster. The initial page load dropped by more than a third.
• A Raspberry Pi’s hostname no longer reverts on its own after a reboot — a repeated, confusing bug on the team’s own test cluster, now fixed at the root cause.
• A firmware-update notice on a Raspberry Pi no longer appears when there’s no actual update pending.
• A maintenance action (reboot, update, and so on) that missed the exact moment a node reconnected could previously stay stuck showing the node as taken out of service even once it was healthy again; a periodic recheck now catches and clears that automatically.

Known limitations

None outstanding — this release’s two hardware-dependent features (the rescue-disk behavior above, and the hostname fix) were both confirmed working on a real cluster shortly after release.
