ProxiFyre 2.2.1 Release Notes

This is a maintenance release focused on stability, performance, and usability improvements over 2.2.0.

🐛 Bug Fixes

• Resolver queue & TCP mapper hardening (#136): Fixed potential races and leaks in the SOCKS local router by serializing lifecycle operations, gating resolver shutdown after stop_filter(), and rolling back state on start() failures. This makes startup/shutdown sequences more robust under load.
• Immediate log output (netlib/src/log/log.h): Added an explicit stream.flush() after osyncstream::emit() so log messages appear on the console without buffering delays. The flush is wrapped in try/catch so I/O errors during logging cannot terminate the application.
• Gateway MAC resolution hardening (network_adapter_info.h): Rejects ARP/NDP cache entries in NlnsUnreachable / NlnsIncomplete states, requires an exact ETH_ALEN physical-address length (preventing silent truncation), and verifies the MAC is not all zeros before use. This prevents invalid gateway MACs from being propagated into NDP/ARP programming.

⚡ Performance

• Faster tunnel startup: Gateway MAC resolution now uses a fast path via GetIpNetEntry2() to consult the existing ARP/NDP cache before falling back to the slower ResolveIpNetEntry2(). Already-resolved gateways are skipped entirely. In typical scenarios this reduces tunnel startup time from ~8 seconds to near-instant.

🛠️ Service / CLI Improvements

• Cleaner install/uninstall output (#137, ProxiFyre/Program.cs): Suppresses duplicate Topshelf installer messages and prints a single, unambiguous status line for service install / uninstall operations. Failure output is now written to stderr, and a typo in the service description was corrected.

📖 Documentation

• README: Updated to reflect current UDP support and related enhancements.
