 # Changelog
 
+## 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.
