txeh-v1.8.0

Features

• DNS cache flush after hosts file changes (#43, #48)
  • Library: FlushDNSCache() function, AutoFlush option in HostsConfig
  • CLI: --flush / -f flag, TXEH_AUTO_FLUSH=1 env var
  • macOS: dscacheutil -flushcache + killall -HUP mDNSResponder
  • Linux: resolvectl flush-caches (systemd 239+), falls back to systemd-resolve --flush-caches
  • Windows: ipconfig /flushdns
  • Flush failures are non-fatal. The hosts file is saved, a warning is printed to stderr.

Improvements

• Refactored CLI mutation commands (add, remove host/ip/cidr/comment) to use shared saveHosts helper
• Descriptive error message when Linux has no systemd-resolved (explains that flushing isn't needed)
• Source citations in platform flush implementations (man pages, vendor docs)

Fixes

• Build-tag platform-specific tests so they only compile on the correct OS
• Bump Go from 1.24.4 to 1.24.7 (fixes GO-2025-3956 os/exec.LookPath vuln)

Documentation

• CLI reference: --flush flag, TXEH_AUTO_FLUSH, platform requirements table
• Troubleshooting: cross-reference to --flush from manual flush instructions
