EasyTier: all versions and old releases

🚀 New Features
- Windows UDP broadcast relay — When enabled, UDP broadcast packets from your PC are forwarded to other devices in the virtual network, allowing LAN-dependent apps like game discovery and DLNA to work across the VPN. Disabled by default; enable via --enable-udp-broadcast-relay, environment variable, or Web UI toggle. Windows only, requires admin privileges.@KKRainbow #2222
- HarmonyOS config persistence and sharing — Configs on HarmonyOS are now saved locally and survive restarts. Share your network config with others via a single link. Route aggregation has been optimized to reduce redundant entries.@FrankHan052176 #2227
🐞 Bug Fixes
- Fixed the probabilistic connection establishment issue in QUIC Proxy — QUIC Proxy had a chance of connection failure when packets were lost. Instead, QUIC open_bi is used to handle connection establishment.@21paradox #2216
- Fixed device identity loss and web dashboard crash — Machine ID is now persisted across restarts and upgrades, preventing re-authentication after updates. Also fixed the web dashboard crashing on malformed packets.@KKRainbow #2215
- Fixed memory creep during long runs — Fixed a resource leak that caused memory usage to grow over time when running EasyTier for extended periods.@KKRainbow #2211
- More forgiving ACL config — ACL rules in config files no longer require every field to be filled in. Missing fields now use sensible defaults instead of causing load errors.@fanyang89 #2206
- Clearer reconnect error messages — When manual reconnection fails, the error now tells you exactly what went wrong — DNS, connection, or handshake — instead of a generic timeout.@fanyang89 #2062
- Missing CLI help text added — Previously undocumented CLI subcommands and flags now have proper --help descriptions.@fanyang89 #2213
