AlexRosbach/LanLens v1.5.8 on GitHub

Highlights

LanLens 1.5.8 focuses on first-run usability, SNMP extensibility, and a new topology view for understanding how devices relate to each other.

Fresh installs now detect the primary host IPv4 subnet, persist it as the initial ARP scan range, and start an immediate first-run network scan.
Added custom SNMP OID/table polling with configurable target tags and stored latest results per SNMP target.
Added Settings UI and API endpoints for custom SNMP queries and latest custom SNMP results.
Added an opt-in Network Topology view under Settings -> Features for inventory relationships, SNMP switch-port mappings, and passive topology edges.
Grouped the sidebar into Monitor, Analyze, Manage, and Admin sections.
Improved the topology map with pan, zoom, reset controls, offline-device filtering, draggable cards, and better dense-layout spacing.

Ignored common Linux bridge interfaces such as br0 and bridge0 during first-run subnet detection.
Reduced SNMP custom-result payloads in Settings and kept vendor detection coverage focused.
Isolated custom SNMP query failures from the main switch poll path while retaining diagnostics.
Cached SNMP endpoint lookups in Network Topology.
Completed missing Italian and Chinese topology/sidebar translations.
Kept Network Topology stable when the topology API temporarily fails.
Made unknown device-class filtering stable across language changes.
