 # Changelog
 
+## 2025-02-27 - 3.16.9 - fix(portproxy)
+Extend domain input validation to support string arrays in port proxy configurations.
+
+- Modify IDomainConfig interface to allow domain specification as string array.
+- Update connection setup logic to handle multiple domain patterns.
+- Enhance domain rejection logging to include all domain patterns.
+
+## 2025-02-27 - 3.16.8 - fix(PortProxy)
+Fix IP filtering for domain and global default allowed lists and improve port-based routing logic.
+
+- Improved logic to prioritize domain-specific allowed IPs over global defaults.
+- Fixed port-based rules application to handle global port ranges more effectively.
+- Enhanced rejection handling for unauthorized IP addresses in both domain-specific and default global lists.
+
+## 2025-02-27 - 3.16.7 - fix(PortProxy)
+Improved IP validation logic in PortProxy to ensure correct domain matching and fallback
+
+- Refactored the setupConnection function inside PortProxy to enhance IP address validation.
+- Domain-specific allowed IP preference is applied before default list lookup.
+- Removed redundant condition checks to streamline connection rejection paths.
+
+## 2025-02-27 - 3.16.6 - fix(PortProxy)
+Optimize connection cleanup logic in PortProxy by removing unnecessary delays.
+
+- Removed multiple await plugins.smartdelay.delayFor(0) calls.
+- Improved performance by ensuring timely resource release during connection termination.
+
+## 2025-02-27 - 3.16.5 - fix(PortProxy)
+Improved connection cleanup process with added asynchronous delays
+
+- Connection cleanup now includes asynchronous delays for reliable order of operations.
+
+## 2025-02-27 - 3.16.4 - fix(PortProxy)
+Fix and enhance port proxy handling
+
+- Ensure that all created proxy servers are correctly checked for listening state.
+- Corrected the handling of ports and domain configurations within port proxy setups.
+- Expanded test coverage for handling multiple concurrent and chained proxy connections.
+
+## 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
+
+- Resolved an issue where the cleanup timer in the PortProxy class did not reset correctly if both incoming and outgoing data events were triggered without clearing flags.
+
+## 2025-02-26 - 3.14.1 - fix(PortProxy)
+Increased default maxConnectionLifetime for PortProxy to 600000 ms
+
+- Updated PortProxy settings to extend default maxConnectionLifetime to 10 minutes.
+
+## 2025-02-26 - 3.14.0 - feat(PortProxy)
+Introduce max connection lifetime feature
+
+- Added an optional maxConnectionLifetime setting for PortProxy.
+- Forces cleanup of long-lived connections based on inactivity or lifetime limit.
+
 ## 2025-02-25 - 3.13.0 - feat(core)
 Add support for tagging iptables rules with comments and cleaning them up on process exit
