• UDP 通信模式: 新增 UDP Server 与 UDP Client 配置页面和完整收发支持，并补充连接控制器、设置面板及串口窗口测试

• 接收文本净化: 文本接收模式会过滤 ANSI 转义序列，避免终端控制码污染显示内容
• 连接配置收敛: 移除重复的内联连接编辑器，由 SettingsPanel 统一管理串口、TCP 与 UDP 配置
• 串口占位项识别: 将“无可用串口”占位项正确识别为串口类型，避免连接模式误判

• UDP communication modes: Added UDP Server and UDP Client configuration pages with complete send/receive support, plus coverage for the connection controller, settings panel, and serial port widget

• Received text sanitization: Text receive mode now filters ANSI escape sequences so terminal control codes do not pollute displayed content
• Consolidated connection settings: Removed the duplicate inline connection editor; SettingsPanel is now the single configuration source for serial, TCP, and UDP connections
• Serial placeholder detection: The no-port placeholder is now classified as a serial entry, preventing connection-mode misclassification

• 状态栏日志链接: 状态栏日志路径改为应用内链接

• Status-bar log link: The status-bar log path is now an in-app link — clicking it flushes and then opens the current log file. The filename is length/NULL-validated and HTML-escaped, the tooltip shows the absolute path, a placeholder is shown when logging is off, and flush/open failures now raise a warning

• 连接稳定性: 修复连接回归问题，涵盖 isOpen 状态判断、停止流程与 UDP/TCP 发送队列
• 日志: 完成多端口日志开关与日志写入相关修复
• 数据处理: 修正 CRC-16/USB 校验计算 (e6ab4ee)
• UI 细节: 修复工具栏动作的选中状态；设置面板在切换标签页时自适应尺寸

• Connection stability: Fixed connection regressions covering isOpen state checks, the stop sequence, and the UDP/TCP send queue
• Logging: Completed multi-port log-toggle and log-writing fixes
• Data handling: Corrected the CRC-16/USB checksum calculation
• UI details: Fixed toolbar action checked states; the settings panel now adapts its size when switching tabs

• 串口文本安全显示: 接收区、日志输出和文本解码链路现在会对不可见控制字符进行净化处理，保留换行、回车和 Tab，并将其他控制字符替换为占位符，避免异常字符污染界面与日志

• 稳定性: 修复 SQLiteAdapter 连接复用与清理问题，改用唯一连接名、参数化 SQL、UPSERT 与更稳妥的关闭顺序，提升本地配置和许可证数据写入可靠性
• 网络资源管理: 修复 UDP/TCP 相关对象的 parent 与释放逻辑，减少连接切换和销毁过程中的泄漏风险

• Safer serial text rendering: The receive pane, log output, and text-decoding path now sanitize non-printable control characters while preserving line breaks, carriage returns, and tabs. Other control characters are replaced with placeholders to keep the UI and logs readable

• Stability: Fixed SQLiteAdapter connection reuse and cleanup issues by using unique connection names, parameterized SQL, UPSERT handling, and a safer close sequence, improving reliability for local configuration and license data writes
• Network resource handling: Fixed parent ownership and cleanup logic for UDP/TCP-related objects to reduce leak risks during connection switching and teardown
