Release Notes

Version 1.3.0 - Code-review hardening. Get-SnmpNeighbors now queries untested nodes by default (Reachable = $null), fixing the import-then-discover workflow, with an -OnlyReachable opt-in switch. Invoke-SnmpWalk redacts the community string from verbose output, validates all parameters (SNMP version set, IP/FQDN, OID format, argument-injection guard), restricts binary resolution to Application, and documents process-list exposure. LLDP/CDP parsing hardened (value-only, octet-validated, Hex-STRING aware) and clearly documented as best-effort. Export-DrawIO de-duplicates node IPs and parents nodes into their matching subnet containers. Invoke-PortScan validates port/timeout ranges and drops TCP 161 (SNMP is UDP). Resolve-IPHostname now honors -TimeoutSeconds via async DNS. Example wizard uses real CIDR host enumeration (with a /22 scan cap) instead of assuming /24.
