3.34.0

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 - 3.34.0 - feat(core)
+Improve wildcard domain matching and enhance NetworkProxy integration in PortProxy. Added support for TLD wildcards and complex wildcard patterns in the router, and refactored TLS renegotiation handling for stricter SNI enforcement.
+
+- Added support for TLD wildcard matching (e.g., 'example.*') to improve domain routing.
+- Implemented complex wildcard pattern matching (e.g., '*.lossless*') in the router.
+- Enhanced NetworkProxy integration by initializing a single NetworkProxy instance and forwarding TLS connections accordingly.
+- Refactored TLS renegotiation handling to terminate connections on SNI mismatch for stricter enforcement.
+- Updated tests to cover the new wildcard matching scenarios.
+
+## 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
+
+- Added ITlsSessionInfo interface and a global tlsSessionCache to track TLS session IDs for session resumption
+- Implemented a cleanup timer for the TLS session cache with startSessionCleanupTimer and stopSessionCleanupTimer
+- Enhanced extractSNIInfo to return detailed SNI information including session IDs, ticket details, and resumption status
+- Updated renegotiation handlers to use extractSNIInfo for proper SNI extraction during TLS rehandshake
+
+## 2025-03-11 - 3.30.8 - fix(core)
+No changes in this commit.
+
+
+## 2025-03-11 - 3.30.7 - fix(PortProxy)
+Improve TLS renegotiation SNI handling by first checking if the new SNI is allowed under the existing domain config. If not, attempt to find an alternative domain config and update the locked domain accordingly; otherwise, terminate the connection on SNI mismatch.
+
+- Added a preliminary check against the original domain config to allow re-handshakes if the new SNI matches allowed patterns.
+- If the original config does not allow, search for an alternative domain config and validate IP rules.
+- Update the locked domain when allowed, ensuring connection reuse with valid certificate context.
+- Terminate the connection if no suitable domain config is found or IP restrictions are violated.
+
+## 2025-03-11 - 3.30.6 - fix(PortProxy)
+Improve TLS renegotiation handling in PortProxy by validating the new SNI against allowed domain configurations. If the new SNI is permitted based on existing IP rules, update the locked domain to allow connection reuse; otherwise, terminate the connection to prevent misrouting.
+
+- Added logic to check if a new SNI during renegotiation is allowed by comparing IP rules from the matching domain configuration.
+- Updated detailed logging to indicate when a valid SNI change is accepted and when it results in a mismatch termination.
+
+## 2025-03-10 - 3.30.5 - fix(internal)
+No uncommitted changes detected; project files and tests remain unchanged.
+
+
+## 2025-03-10 - 3.30.4 - fix(PortProxy)
+Fix TLS renegotiation handling and adjust TLS keep-alive timeouts in PortProxy implementation
+
+- Allow TLS renegotiation data without an explicit SNI extraction to pass through, ensuring valid renegotiations are not dropped (critical for Chrome).
+- Update TLS keep-alive timeout from an aggressive 30 minutes to a more generous 4 hours to reduce unnecessary reconnections.
+- Increase inactivity thresholds for TLS connections from 20 minutes to 2 hours with an additional verification interval extended from 5 to 15 minutes.
+- Adjust long-lived TLS connection timeout from 45 minutes to 8 hours for improved certificate context refresh in chained proxy scenarios.
+
+## 2025-03-10 - 3.30.3 - fix(classes.portproxy.ts)
+Simplify timeout management in PortProxy and fix chained proxy certificate refresh issues
+
+- Reduced TLS keep-alive timeout from 8 hours to 30 minutes to ensure frequent certificate refresh
+- Added aggressive TLS state refresh after 20 minutes of inactivity and secondary verification checks
+- Lowered long-lived TLS connection lifetime from 12 hours to 45 minutes to prevent stale certificates
+- Removed configurable timeout settings from the public API in favor of hardcoded sensible defaults
+- Simplified internal timeout management to reduce code complexity and improve certificate handling in chained proxies
+
+## 2025-03-10 - 3.31.0 - fix(classes.portproxy.ts)
+Simplified timeout management and fixed certificate issues in chained proxy scenarios
+
+- Dramatically reduced TLS keep-alive timeout from 8 hours to 30 minutes to ensure fresh certificates
+- Added aggressive certificate refresh after 20 minutes of inactivity (down from 4 hours)
+- Added secondary verification checks for TLS refresh operations
+- Reduced long-lived TLS connection lifetime from 12 hours to 45 minutes
+- Removed configurable timeouts completely from the public API in favor of hardcoded sensible defaults
+- Simplified interface by removing no-longer-configurable settings while maintaining internal compatibility
+- Reduced overall code complexity by eliminating complex timeout management
+- Fixed chained proxy certificate issues by ensuring more frequent certificate refreshes in all deployment scenarios
+
+## 2025-03-10 - 3.30.2 - fix(classes.portproxy.ts)
+Adjust TLS keep-alive timeout to refresh certificate context.
+
+- Modified TLS keep-alive timeout for connections to 8 hours to refresh certificate context.
+- Updated timeout log messages for clarity on TLS certificate refresh.
+
 ## 2025-03-10 - 3.30.1 - fix(PortProxy)
 Improve TLS keep-alive management and fix whitespace formatting
