- New installs start from widgets.RECOMMENDED, packed row by row for the enabled plugins; the edit drawer can reset a dashboard to it. - Host Agent — Resources folds into Hosts — Overview (which gains load 1m), UniFi — Devices into UniFi — Overview; migration 0032 moves existing dashboards onto the survivors. - The Overview labels what it counts (hosts, monitors up/down/pending, alerts firing) and lists firing alerts and down monitors with since-times. - Uptime polls every 5 minutes (poll_seconds) instead of every cycle.
