3.33.0

Added enhanced connection handling to fix issues with both initial connections and TLS session resumption:

1. Improved debugging for connection setup with detailed logging
2. Added explicit timeout for backend connections to prevent hanging connections
3. Enhanced error recovery for connection failures with faster client notification
4. Added detailed session tracking to maintain domain context across TLS sessions
5. Fixed handling of TLS renegotiation with improved activity timestamp updates

This should address the issue where initial connections may fail but subsequent retries succeed,
as well as ensuring proper certificate selection for resumed TLS sessions.

 # Changelog
 
+## 2025-03-11 - 3.33.0 - feat(portproxy)
+Add browser-friendly mode and SNI renegotiation configuration options to PortProxy
+
+- Introduce new properties: browserFriendlyMode (default true) to optimize handling for browser connections.
+- Add allowRenegotiationWithDifferentSNI (default false) to enable or disable SNI changes during renegotiation.
+- Include relatedDomainPatterns to define patterns for related domains that can share connections.
+- Update TypeScript interfaces and internal renegotiation logic to support these options.
+
+## 2025-03-11 - 3.32.2 - fix(PortProxy)
+Simplify TLS handshake SNI extraction and update timeout settings in PortProxy for improved maintainability and reliability.
+
+- Removed legacy and deprecated fields related to chained proxy configurations (isChainedProxy, chainPosition, aggressiveTlsRefresh).
+- Refactored the extractSNI functions to use a simpler, more robust approach for TLS ClientHello processing.
+- Adjusted default timeout and keep-alive settings to more standard values (e.g. initialDataTimeout set to 60s, socketTimeout to 1h).
+- Eliminated redundant TLS session cache and deep TLS refresh logic.
+- Improved logging and error handling during connection setup and renegotiation phases.
+
+## 2025-03-11 - 3.32.1 - fix(portproxy)
+Relax TLS handshake and connection timeout settings for improved stability in chained proxy scenarios; update TLS session cache defaults and add keep-alive flags to connection records.
+
+- Increased TLS session cache maximum entries from 10,000 to 20,000, expiry time from 24 hours to 7 days, and cleanup interval from 10 minutes to 30 minutes
+- Relaxed socket timeouts: standalone connections now use up to 6 hours, with chained proxies adjusted for 5–6 hours based on proxy position
+- Updated inactivity, connection, and initial handshake timeouts to provide a more relaxed behavior under high-traffic chained proxy scenarios
+- Increased keepAliveInitialDelay from 10 seconds to 30 seconds and introduced separate incoming and outgoing keep-alive flags
+- Enhanced TLS renegotiation handling with more detailed logging and temporary processing flags to avoid duplicate processing
+- Updated NetworkProxy integration to use optimized connection settings and more aggressive application-level keep-alive probes
+
+## 2025-03-11 - 3.32.0 - feat(PortProxy)
+Enhance TLS session cache, SNI extraction, and chained proxy support in PortProxy. Improve handling of multiple and fragmented TLS records, and add new configuration options (isChainedProxy, chainPosition, aggressiveTlsRefresh, tlsSessionCache) for robust TLS certificate refresh.
+
+- Implement TlsSessionCache with configurable cleanup, eviction, and statistics.
+- Improve extractSNIInfo to process multiple TLS records and partial handshake data.
+- Add new settings to detect chained proxy scenarios and adjust timeouts accordingly.
+- Enhance TLS state refresh with aggressive probing and deep refresh sequence.
+
+## 2025-03-11 - 3.31.2 - fix(PortProxy)
+Improve SNI renegotiation handling by adding flexible domain configuration matching on rehandshake and session resumption events.
+
+- When a rehandshake is detected with a changed SNI, first check existing domain config rules and log if allowed.
+- If the exact domain config is not found, additionally attempt flexible matching using parent domain and wildcard patterns.
+- For resumed sessions, try an exact match first and then use fallback logic to select a similar domain config based on matching target IP.
+- Enhanced logging added to help diagnose missing or mismatched domain configurations.
+
+## 2025-03-11 - 3.31.1 - fix(PortProxy)
+Improve TLS handshake buffering and enhance debug logging for SNI forwarding in PortProxy
+
+- Explicitly copy the initial TLS handshake data to prevent mutation before buffering
+- Log buffered TLS handshake data with SNI information for better diagnostics
+- Add detailed error logs on TLS connection failures, including server and domain config status
+- Output additional debug messages during ClientHello forwarding to verify proper TLS handshake processing
+
 ## 2025-03-11 - 3.31.0 - feat(PortProxy)
 Improve TLS handshake SNI extraction and add session resumption tracking in PortProxy
