 # Changelog
 
+## 2025-03-07 - 3.28.4 - fix(router)
+Improve path pattern matching and hostname prioritization in router
+
+- Enhance path pattern matching capabilities
+- Ensure hostname prioritization in routing logic
+
+## 2025-03-06 - 3.28.3 - fix(PortProxy)
+Ensure timeout values are within Node.js safe limits
+
+- Implemented `ensureSafeTimeout` to keep timeout values under the maximum safe integer for Node.js.
+- Updated timeout configurations in `PortProxy` to include safety checks.
+
+## 2025-03-06 - 3.28.2 - fix(portproxy)
+Adjust safe timeout defaults in PortProxy to prevent overflow issues.
+
+- Adjusted socketTimeout to maximum safe limit (~24.8 days) for PortProxy.
+- Adjusted maxConnectionLifetime to maximum safe limit (~24.8 days) for PortProxy.
+- Ensured enhanced default timeout settings in PortProxy.
+
+## 2025-03-06 - 3.28.1 - fix(PortProxy)
+Improved code formatting and readability in PortProxy class by adjusting spacing and comments.
+
+- Adjusted comment and spacing for better code readability.
+- No functional changes made in the PortProxy class.
+
 ## 2025-03-06 - 3.28.0 - feat(router)
 Add detailed routing tests and refactor ProxyRouter for improved path matching
