v1.2 — 26 May 2026#
Onboarding + persistence + locate
Onboarding wizard for first-boot setup (network, LED configuration). Node registry now persists to EEPROM — discovered nodes survive reboots with cached identity/compatibility. Serial number display in detail page. Locate feature changed to REST-based (POST /api/locate to node, requires dualETH v7.6+). Offline-aware UI — configuration/trends/locate hidden when node offline. Bug fixes: Port A/B loading delays for single-listener compatibility, EEPROM cache versioning prevents format mismatches. EEPROM expanded to 4096 bytes for node cache (32 nodes × 94 bytes).
v1.1 — 4 May 2026#
DHCP fallback + fleet management
DHCP fallback server (acts as the LAN's DHCP server when no upstream replies). Fleet-management additions to the SPA: universe map with conflict highlighting, bulk node operations, configuration backup/restore with per-target diff preview, Locate (ArtPoll burst), live sparklines, server-side persisted node tags. New REST surface: /api/dhcp-server/leases, /api/nodes/locate, /api/tags. EEPROM bumped to 2304 bytes for lease + tag regions.
