v1.1.0 — mdns-grep: regex-based mDNS service discovery

What's New

The only Go mDNS library with regex-based service discovery — now with a cross-platform CLI tool.

mdns-grep CLI

Discover mDNS services on your local network using regex patterns — like grep for mDNS.

mdns-grep                              # enumerate all services
mdns-grep _http._tcp                   # find HTTP services
mdns-grep -regex '_https?._tcp'        # regex: match HTTP + HTTPS
mdns-grep -scan -timeout 10s           # full 2-phase network scan
mdns-grep -json _ipp._tcp              # JSON output for scripting
mdns-grep -iface eth0 _ssh._tcp        # bind to specific interface
mdns-grep -6                           # enable IPv6

Bug Fixes (10 issues)

• Fix regex recompile every call — cache compiled patterns in sync.Map
• Fix server.sendResponse nil pointer — safe type assertion + nil checks for IPv4/IPv6 listeners
• Fix server recv goroutine leak — check shutdown after ReadFrom
• Fix client recv goroutine leak — WaitGroup + defer cleanup + close msgCh
• Fix sendQuery error logic — only return error when ALL sends fail
• Fix zone.gettxt() nil pointer — nil checks for pointer types
• Fix server_test.go — t.Fatalf from goroutine → atomic.Value
• Fix zone_test.go — TXT record compare pointer vs value
• Fix dead code — remove unused strings.Split
• Add warning when Entries channel full (was silent drop)

Dependency Cleanup

Removed heavy internal dependencies. 467 → 5 deps (only miekg/dns + golang.org/x/*).

Binaries

Pre-built for 14 platforms. UPX-compressed where supported.
