ℹ️ Platform Updates

Linux support postponed. Linux support was initially planned for this release but has been postponed due to significant development challenges. Implementing feature parity with Windows and macOS requires substantial architectural work and effort. After initial development attempts encountered multiple technical issues, we decided to focus on stabilizing the Windows and macOS versions first. Linux support remains in our roadmap, but no release timeline has been finalized. See commit 6dfed95 for details.

v2.0

ProxyBridge v2.0 — Major Update 🚀

ProxyBridge version 2.0 comes with multiple major features, improvements, and bug fixes to enhance stability, compatibility, and control.

---

🆕 New Features

• UDP Proxy Support — You can now route UDP traffic through your proxy.
• Proxy Authentication — Supports both HTTP Basic Auth and SOCKS5 Authentication.
• Proxy Tester — Built-in proxy connection tester to verify ProxyBridge and proxy server connections.
• System Connection Logging — Log all system TCP and UDP connections with process IDs, even without rules.
• Proxy Rule Enhancements
  • Add multiple process names in a single rule.
  • Process name now supports wildcards (e.g. firefo*.exe or *.bin).
  • Rules now support Port and IP-based routing — specify individual ports, IPs, ranges, or wildcard IPs.
  • Rules support protocol-based routing — create rules for TCP, UDP, or BOTH.
  • Add full process path instead of just the process name. You can browse and select processes directly.
• DNS via Proxy — Choose whether DNS requests go directly or through the proxy.
• SOCKS5 UDP Associate Support — SOCKS5 proxy now supports UDP association.
• Editable Rules — You can now edit or delete existing proxy rules.
• Update Checker — Built-in application update checker for future releases.

---

🐞 Bug Fixes

• Loopback Packets — Fixed issue where loopback packets via ProxyBridge were dropped by Windows. Loopback addresses are now directed as direct connections.
• Broadcast & Multicast Loops — Fixed issues with broadcast and multicast packets being looped. These are now monitored and always routed to their original destinations instead of through the proxy.

---

⚙️ Improvements

• Improved proxy connection stability.
• Improved GUI performance.
• CLI Enhancements
  • Added logging support (disabled by default).
  • Now uses AOT compiled binaries for better performance and lower resource usage.
• Removed dependency on default proxy configuration.

v1.1

This release adds a lightweight GUI, improves the CLI, introduces traffic blocking rules (and multiple-rule support), fixes a process-detection hang, and brings several performance improvements.

Added

• GUI - A simple graphical interface, useful for users who prefer not to use the CLI.
• Updated CLI option - CLI flags refined for clarity and new features.
• Option to block traffic - Add rules that block matched applications.
• Multiple Rule option - You can now supply multiple.
• Installation - Installer exe in now available instead of portable zip file.

Fixed
