 # Changelog
 
+## 2025-02-21 - 3.9.3 - fix(PortProxy)
+Fix handling of optional outgoing socket in PortProxy
+
+- Refactored the cleanUpSockets function to correctly handle cases where the outgoing socket may be undefined.
+- Ensured correct handling of socket events with non-null assertions where applicable.
+- Improved robustness in connection establishment and cleanup processes.
+
+## 2025-02-21 - 3.9.2 - fix(PortProxy)
+Improve timeout handling for port proxy connections
+
+- Added console logging for both incoming and outgoing side timeouts in the PortProxy class.
+- Updated the timeout event handlers to ensure proper cleanup of connections.
+
+## 2025-02-21 - 3.9.1 - fix(dependencies)
+Ensure correct ordering of dependencies and improve logging format.
+
+- Reorder dependencies in package.json for better readability.
+- Use pretty-ms for displaying time durations in logs.
+
+## 2025-02-21 - 3.9.0 - feat(smartproxy.portproxy)
+Add logging of connection durations to PortProxy
+
+- Track start times for incoming and outgoing connections.
+- Log duration of longest running incoming and outgoing connections every 10 seconds.
+
 ## 2025-02-21 - 3.8.1 - fix(plugins)
 Simplified plugin import structure across codebase
