 # Changelog
 
+## 2025-02-27 - 3.16.3 - fix(PortProxy)
+Refactored PortProxy to support multiple listening ports and improved modularity.
+
+- Updated PortProxy to allow multiple listening ports with flexible configuration.
+- Moved helper functions for IP and port range checks outside the class for cleaner code structure.
+
+## 2025-02-27 - 3.16.2 - fix(PortProxy)
+Fix port-based routing logic in PortProxy
+
+- Optimized the handling and checking of local ports in the global port range.
+- Fixed the logic for rejecting or accepting connections based on predefined port ranges.
+- Improved handling of the default and specific domain configurations during port-based connections.
+
+## 2025-02-27 - 3.16.1 - fix(core)
+Updated minor version numbers in dependencies for patch release.
+
+- No specific file changes detected.
+- Dependencies versioning adjusted for stability.
+
+## 2025-02-27 - 3.16.0 - feat(PortProxy)
+Enhancements made to PortProxy settings and capabilities
+
+- Added 'forwardAllGlobalRanges' and 'targetIP' to IPortProxySettings.
+- Improved PortProxy to forward connections based on domain-specific configurations.
+- Added comprehensive handling for global port-range based connection forwarding.
+- Enabled forwarding of all connections on global port ranges directly to global target IP.
+
+## 2025-02-27 - 3.15.0 - feat(classes.portproxy)
+Add support for port range-based routing with enhanced IP and port validation.
+
+- Introduced globalPortRanges in IPortProxySettings for routing based on port ranges.
+- Improved connection handling with port range and domain configuration validations.
+- Updated connection logging to include the local port information.
+
 ## 2025-02-26 - 3.14.2 - fix(PortProxy)
 Fix cleanup timer reset for PortProxy
