 # Changelog
 
+## 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.
+
+- In the TLS handshake alert for certificate_expired (0x2F), changed the alert level from 0x02 (fatal) to 0x01 (warning).
+- 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)
 Increase delay timings for TLS alert transmission in session ticket blocking to allow graceful socket termination
