ProxyBridge v4.0.0 Platform Notice: v4.0.0 is currently available for Windows only. Linux and macOS builds are in pre-development and will be released in a future update.

✨ New Features 🌐 IPv6 Support https://github.com/InterceptSuite/ProxyBridge/issues/78 Full IPv6 support across logging, routing, and proxy - ProxyBridge now handles IPv6 end-to-end. 🔀 Multiple Proxy Configurations https://github.com/InterceptSuite/ProxyBridge/issues/44 Save multiple proxy configurations and assign different proxies to different rules simultaneously. No more swapping configs manually. 👤 Profiles https://github.com/InterceptSuite/ProxyBridge/issues/98 Create, switch, import, and export profiles - each profile bundles your full ProxyBridge configuration into a single portable file, making it easy to manage separate setups for different use cases. 🌍 Domain Name Forwarding https://github.com/InterceptSuite/ProxyBridge/issues/138 ProxyBridge now sends domain names directly to the proxy server instead of resolving them locally first, enabling proper remote DNS resolution. Closes #138. 🔍 Log Filters https://github.com/InterceptSuite/ProxyBridge/issues/97 https://github.com/InterceptSuite/ProxyBridge/issues/150 Filter connection logs by process, IP, port, protocol, and action using include/exclude rules with wildcard support. ⚡ Toolbar Quick Actions https://github.com/InterceptSuite/ProxyBridge/issues/102 Proxy rules and config are now accessible directly from the main toolbar. 🧹 Auto-Clear Connection Logs Optionally auto-trim connection logs when they exceed the configured limit. 🖥️ CLI Rewritten in C The CLI has been rewritten from scratch - migrated from C# to C for improved performance and portability.

🐛 Bug Fixes

• Relay sockets loopback fix - Relay sockets were bound to loopback only; now binds to INADDR_ANY so real traffic reaches the relay correctly (TCP + UDP)
• SOCKS5 UDP ASSOCIATE 0.0.0.0 fix - Now substitutes the proxy's resolved IP, resolving Winsock error 10049
• Disabled proxy rules not persisting - Disabled rule state is now correctly saved and restored on startup and profile switch https://github.com/InterceptSuite/ProxyBridge/issues/107
• ++ in process names - Processes like notepad++.exe were rejected by the rule validator; now handled correctly. Closes #157
• Log filter Save clearing entries - Saving a log filter no longer clears existing log entries; it now re-filters in place
• UDP - Multiple UDP bugs fixed; real-time UDP communication now fully supported https://github.com/InterceptSuite/ProxyBridge/issues/172 https://github.com/InterceptSuite/ProxyBridge/issues/89
• UDP Session Termination - UDP sessions are now properly terminated https://github.com/InterceptSuite/ProxyBridge/issues/133
• ICMP - ICMP handling issues resolved
• Loopback address - Loopback address routing issues fixed
• Proxy rule wildcard - Wildcard matching errors in proxy rules fixed https://github.com/InterceptSuite/ProxyBridge/issues/93
• Rule disabled state - Fixed rules not staying disabled after restart https://github.com/InterceptSuite/ProxyBridge/issues/107
• Memory leak - Fixed memory leak caused by timed-out sessions not being cleaned up
• ESC key - ESC now closes popup windows. Closes #152
• UI/UX - Multiple UI fixes including proxy config and rule shortcuts on the home screen https://github.com/InterceptSuite/ProxyBridge/issues/101
• Binary optimizations - Reduced binary size and improved startup performance
• Proxy rule engine - Internal rule matching optimized
• Minimize - Fixed Windows Minimize isses https://github.com/InterceptSuite/ProxyBridge/issues/142

🗑️ Removed

• DNS via Proxy - Removed the DNS via Proxy feature along with all associated UI, settings, and C-layer code. Use Domain Name Forwarding instead for remote DNS resolution.
