Changelog

v4.12.0 — 2026-09-29

Health endpoint split out from the event stream: GET /api/v1/health now answers 200 ok with no key required, so uptime checks stop counting a keyless probe as an error. Board reconnect backoff is gentler on repeated edge drains.

v4.11.3 — 2026-09-12

Stream reconnect no longer replays the last batch twice after an edge node is drained. Board sparklines redraw on a shared frame, cutting idle CPU on long-lived tabs.

v4.11.2 — 2026-09-08

Stream relay reconnect is now instant on flaky mobile networks. Asset manifest revalidation moved to the edge.

v4.11.0 — 2026-08-27

Retention window is configurable up to 30 days. Reduced idle keep-alive chatter by 40%.

v4.10.4 — 2026-08-12

Fixed a rare duplicate-event replay after a cold start. Board redraw is smoother under load.
