+
+## 2025-03-18 - 4.2.3 - fix(connectionhandler)
+Remove unnecessary delay in TLS session ticket handling for connections without SNI
+
+- Eliminated the extra setTimeout waiting period before cleaning up connections flagged as session_ticket_blocked_no_sni
+- Ensures immediate cleanup and improves connection responsiveness during TLS handshake failures
+
+## 2025-03-18 - 4.2.2 - fix(connectionhandler)
+Ensure proper termination of TLS connections without SNI by explicitly ending the socket after sending the unrecognized_name alert. This prevents the connection from hanging and avoids potential duplicate handling.
+
+- Added socket.end() after uncorking the alert packet in ClientHello handling to force connection closure.
+- Prevents duplicate data events and ensures the warning alert is processed by clients like Chrome.
+
+## 2025-03-17 - 4.2.1 - fix(core)
+No uncommitted changes detected in the project.
+
+
+## 2025-03-17 - 4.2.0 - feat(tlsalert)
+add sendForceSniSequence and sendFatalAndClose helper functions to TlsAlert for improved SNI enforcement
+
+- Introduce sendForceSniSequence to combine multiple alerts and force clients to provide SNI

+- Enhance TLS alert handling for better browser compatibility and error management
+
+## 2025-03-17 - 4.1.16 - fix(tls)
+Improve TLS alert handling in connection handler: use the new TlsAlert class to send proper unrecognized_name alerts when a ClientHello is missing SNI and wait for a retry on the same connection before closing. Also, add alertFallbackTimeout tracking to connection records for better timeout management.
+
+- Replaced hardcoded alert buffers in ConnectionHandler with calls to the TlsAlert class.
+- Removed old warnings and implemented a mechanism to remove existing 'data' listeners and await a new ClientHello.
+- Introduced alertFallbackTimeout property in connection records to track fallback timeout and ensure proper cleanup.
+- Extended the delay before closing the connection after sending an alert, providing the client more time to retry.
+
+## 2025-03-17 - 4.1.15 - fix(connectionhandler)
+Delay socket termination in TLS session resumption handling to allow proper alert processing
+
+- Removed the immediate socket.end() call in finishConnection and moved it inside the setTimeout, ensuring that clients (especially Chrome) have additional time to process the TLS alert before connection termination
+- This prevents premature socket closure on ClientHello without SNI when session tickets are disallowed
+
+## 2025-03-17 - 4.1.14 - fix(ConnectionHandler)
+Use the correct TLS alert data and increase the delay before socket termination when session resumption without SNI is detected.
+
+- Replaced certificateExpiredAlert with serverNameUnknownAlertData for sending the appropriate alert.
+- Increased the cleanup delay from 1000ms to 5000ms to allow a more graceful termination.
+
+## 2025-03-17 - 4.1.13 - fix(tls-handshake)
+Set certificate_expired TLS alert level to warning instead of fatal to allow graceful termination.
+

+- This change avoids abrupt connection termination, enabling a smoother handling of certificate expiration alerts.
+
+## 2025-03-17 - 4.1.12 - fix(classes.pp.connectionhandler)
+Replace unrecognized_name alert data with certificate_expired alert in TLS handshake handling for session resumption without SNI
+
+- Switched the alert payload from serverNameUnknownAlertData to a new certificateExpiredAlert buffer
+- Now sends a fatal certificate_expired alert (code 47) instead of a warning unrecognized_name alert
+- Improves TLS error reporting and encourages immediate disconnection when a ClientHello lacks SNI and session tickets are disallowed
+
+## 2025-03-17 - 4.1.11 - fix(connectionhandler)
+Increase delay before cleaning up connections when session resumption is blocked due to missing SNI, allowing more natural socket termination.
+
+- Changed cleanup delay in ts/classes.pp.connectionhandler.ts from 300ms to 1000ms.
+- This fix ensures that sockets get sufficient time to terminate gracefully.
+
+## 2025-03-16 - 4.1.10 - fix(connectionhandler)

+- Ensures consistent TLS alert behavior during handshake failure.
+
+## 2025-03-16 - 4.1.8 - fix(ConnectionHandler/tls)
+Change the TLS alert sent when a ClientHello lacks SNI: use the close_notify alert instead of handshake_failure to prompt immediate retry with SNI.
+
+- Replaced the previously sent handshake_failure alert (code 0x28) with a close_notify alert (code 0x00) in the TLS session resumption handling in ConnectionHandler.
+- This change encourages clients to immediately retry and include SNI when allowSessionTicket is false.
+
+## 2025-03-16 - 4.1.7 - fix(classes.pp.connectionhandler)
+Improve TLS alert handling in ClientHello when SNI is missing and session tickets are disallowed
+

+- Update the TLS alert sending mechanism to use cork/uncork and a short, fixed delay instead of long timeouts
+- Remove redundant event listeners and excessive cleanup logic after sending the alert
+- Improve code clarity and encourage clients (e.g., Chrome) to retry handshake with SNI more responsively
+
+## 2025-03-16 - 4.1.5 - fix(TLS/ConnectionHandler)
+Improve handling of TLS session resumption without SNI by sending an 'unrecognized_name' alert instead of immediately terminating the connection. This change adds a grace period for the client to retry the handshake with proper SNI and cleans up the connection if no valid response is received.
+
+- Send a TLS warning (unrecognized_name alert, code 112) when a ClientHello is received without SNI and session tickets are disallowed.
+- Utilize socket cork/uncork to ensure the alert is sent as a single packet.
+- Add a 5-second alert timeout and a subsequent 30-second grace period to allow clients to initiate a new handshake with SNI.
+- Clean up and terminate the connection if no valid SNI is provided after the grace period, logging appropriate termination reasons.
+
+## 2025-03-15 - 4.1.4 - fix(ConnectionHandler)

+
+- Replace the fatal alert (0x02/0x40) with a warning alert (0x01/0x70) to notify clients to send SNI.
+- Use socket.write callback to wait 100ms after sending the alert before terminating the connection.
+- Remove the previous short (50ms) delay in favor of a more reliable delay mechanism before cleanup.
+
+## 2025-03-15 - 4.1.2 - fix(connectionhandler)
+Send proper TLS alert before terminating connections when SNI is missing and session tickets are disallowed.
+
+- Added logic to transmit a fatal TLS alert (Handshake Failure) before closing the connection when no SNI is present with allowSessionTicket=false.
+- Introduced a slight 50ms delay after sending the alert to ensure the client receives the alert properly.
+- Applied these changes both for the initial ClientHello and when handling subsequent TLS data.
+
+## 2025-03-15 - 4.1.1 - fix(tls)
+Enforce strict SNI handling in TLS connections by terminating ClientHello messages lacking SNI when session tickets are disallowed and removing legacy session cache code.
+
+- In classes.pp.connectionhandler.ts, if allowSessionTicket is false and no SNI is extracted from a ClientHello, the connection is terminated to force a new handshake with SNI.
+- In classes.pp.snihandler.ts, removed session cache and related cleanup functions used for tab reactivation, simplifying SNI extraction logic.
