 # Changelog
 
+## 2025-03-11 - 3.39.0 - feat(PortProxy)
+Add domain-specific NetworkProxy integration support to PortProxy
+
+- Introduced new properties 'useNetworkProxy' and 'networkProxyPort' in domain configurations.
+- Updated forwardToNetworkProxy to accept an optional custom proxy port parameter.
+- Enhanced TLS handshake processing to extract SNI and, if a matching domain config specifies NetworkProxy usage, forward the connection using the domain-specific port.
+- Refined connection routing logic to check for domain-specific NetworkProxy settings before falling back to default behavior.
+
+## 2025-03-11 - 3.38.2 - fix(core)
+No code changes detected; bumping patch version for consistency.
+
+
+## 2025-03-11 - 3.38.1 - fix(PortProxy)
+Improve SNI extraction handling in PortProxy by passing explicit connection info to extractSNIWithResumptionSupport for better TLS renegotiation and debug logging.
+
+- In the renegotiation handler, create and pass a connection info object (sourceIp, sourcePort, destIp, destPort) instead of a boolean flag.
+- Update the TLS handshake processing to construct a connection info object for detailed SNI extraction and logging.
+- Enhance consistency by using processTlsPacket with cached SNI hints during fallback.
+
 ## 2025-03-11 - 3.38.0 - feat(SniHandler)
 Enhance SNI extraction to support fragmented ClientHello messages, TLS 1.3 early data, and improved PSK parsing
