+## [1.3.4] - 2025-09-13
+
+### Added
+- **Enhanced WebSocket Connection Management**: Robust ping/pong frame handling and automatic reconnection
+  - Fixed ping frame parsing in wsssh.c to properly handle WebSocket ping frames
+  - Added automatic pong responses with correct payload echoing
+  - Implemented WebSocket reconnection logic for both wsssh.c and wsscp.c
+  - Added --interval option for configurable connection retry intervals
+  - Smart timing: 1-second WebSocket reconnections vs 30-second initial connection retries
+
+- **Connection Resilience Features**:
+  - Automatic WebSocket reconnection during active tunnel operations
+  - Configurable retry intervals with --interval option (default: 30 seconds)
+  - Up to 3 reconnection attempts with proper error handling
+  - Seamless tunnel recovery without disrupting active SSH/SCP sessions
+  - Enhanced debug logging for connection state changes
+
+### Changed
+- **wsssh.c and wsscp.c Connection Handling**: Both tools now support automatic WebSocket reconnection
+- **Ping Frame Processing**: Fixed parse_websocket_frame function to accept ping frames (0x89)
+- **Reconnection Timing**: Fast 1-second intervals for WebSocket reconnections, configurable intervals for initial setup
+- **Error Recovery**: Improved resilience to network interruptions and temporary disconnections
+
+### Technical Details
+- **WebSocket Protocol Compliance**: Proper ping/pong frame handling with RFC 6455 compliance
+- **Reconnection Logic**: reconnect_websocket() function for seamless connection recovery
+- **Configuration Options**: Added --interval parameter to both wsssh and wsscp
+- **Backward Compatibility**: All existing functionality preserved, new features are additive
+- **Cross-Tool Consistency**: Identical reconnection behavior between wsssh and wsscp
+
+### Fixed
+- **Ping Frame Parsing**: wsssh.c now correctly parses and responds to WebSocket ping frames
+- **Connection Recovery**: Automatic reconnection when WebSocket connections are lost
+- **Tunnel Stability**: Improved tunnel reliability during network interruptions

 ### Added
@@ -28,6 +63,53 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **Implementation**: Added config file parsing to wssshd.py using configparser
 - **Backward Compatibility**: All existing functionality preserved, config file is optional
 
+## [1.3.2] - 2025-09-13
+
+### Added
+- **Enhanced Client Registration Management**: Improved wssshd client disconnection handling
+  - Clients are marked as "disconnected" instead of immediately removed from registry
+  - 30-second timeout before removing expired client registrations
+  - Automatic cleanup of expired clients with periodic background task
+  - Better resilience to temporary network disconnections
+
+- **Improved Debug Message Clarity**: Enhanced debug output to distinguish between protocol levels
+  - `[WebSocket]` prefix for WebSocket-level messages and events
+  - `[TCP Tunnel]` prefix for TCP tunnel-level messages and events
+  - Clear separation between close frame handling and tunnel operations
+  - More detailed logging for connection state changes
+
+### Changed
+- **WebSocket Close Frame Handling**: Close frames no longer immediately terminate client registration
+  - Close frames trigger reconnection rather than client removal
+  - Client registration persists during temporary disconnections
+  - Improved reliability for unstable network conditions
+
+- **Debug Output Format**: Standardized debug message format across all components
+  - Consistent prefix system for different protocol layers
+  - Clear indication of message source and type
+  - Better troubleshooting capabilities
+
+### Technical Details
+- **Client Registry Structure**: Enhanced client storage with status and timestamp tracking
+  - `clients[client_id] = {'websocket': ws, 'last_seen': timestamp, 'status': 'active'|'disconnected'}`
+  - Automatic status transitions based on connection state
+  - Timestamp-based expiration for disconnected clients
+
+- **Background Cleanup**: Asynchronous cleanup task running every 10 seconds
+  - Removes clients disconnected for more than 30 seconds
+  - Maintains registry cleanliness without affecting active connections
+  - Non-blocking operation that doesn't interfere with normal processing
+
+- **Web Interface Updates**: Enhanced client status display in web management interface
+  - Shows client connection status (active/disconnected)
+  - Displays last seen timestamp for disconnected clients
+  - Improved API responses with detailed client information
+
+### Security
+- **Connection State Tracking**: Better monitoring of client connection states
+- **Timeout-based Cleanup**: Prevents accumulation of stale client registrations
+- **Maintained Security**: All existing security measures preserved during improvements
