MeshMonitor v3.10.0 is a major release featuring a comprehensive database architecture overhaul — 5,672 lines of code removed across 278 files while adding new features and fixing dozens of bugs.

New Features

• Channel drag-and-drop reorder — Rearrange device channel slots with automatic message history migration so your chat history follows the channel
• Dead nodes report — New Security tab section showing nodes not heard from in 7+ days with bulk delete capability
• Rsyslog server setting — Configure remote syslog server in Device Configuration > Network
• Polar grid map overlay — Visual polar grid overlay for directional analysis
• Configurable default map center — Set your preferred starting map location
• Auto responder environment variables — Expose auto responder tokens as environment variables for external scripts
• Millisecond packet timestamps — Sub-second precision in packet monitor with dedicated date column
• OIDC retry on failure — Authentication no longer permanently disables if OIDC provider is temporarily unavailable

Database Architecture Improvements

• Full async migration — All synchronous database calls replaced with async equivalents across all three backends
• Repository pattern — Monolithic DatabaseService decomposed into domain-specific repositories (nodes, messages, telemetry, channels, etc.)
• Centralized migration registry — Clean v3.7 baseline with standardized migration system
• N+1 query elimination — Bulk queries replace per-node loops in security scanner, neighbor info, and node listing
• Cross-database helpers — New col(), upsert(), insertIgnore(), and getAffectedRows() helpers eliminate backend-specific branching

Bug Fixes

• Channel database no longer shadows device channels with the same PSK
• PostgreSQL connection pool exhaustion with large meshes (200+ nodes)
• Local node no longer self-flags security warnings or bounces link quality
• Key mismatch warnings now properly clear after resolution on all backends
• Traceroute race conditions and duplication issues resolved
• Admin keys no longer show as [object Object] in security config
• MQTT detection and visual distinction in traceroutes improved
• Packet monitor shows node names instead of hex IDs on PostgreSQL
