English

• Connection activity lamps: The connection group gains interactive TX/RX and control-line indicator lamps that blink to reflect live traffic and control-line state; the classic control-line UI is retired in favour of the lamps

• Internationalization: Label the format radios Text, not ASCII, in Chinese
• Log directory: Create the log directory before opening the log file

• Cloud Console（云控制台）: 开启后，可在 alithon.com 使用已登录的浏览器实时查看本机端口收发数据；“允许远程发送”“允许远程端口控制”两个独立授权开关，分别控制云端写入数据与远程开关/重配端口；数据仅在有人查看时上传，计入每月流量配额
• 账户体系: 新增账户登录/登出（File 菜单 Account 子菜单），支持“保持登录”持久会话；状态栏右侧实时显示账户状态，菜单项随登录状态自动切换

• 国际化: 修复多处英文源文案与中文翻译，区分不同语境下的 Port 标签

English

• Cloud Console: When enabled, a signed-in browser on alithon.com can view this device's ports live; separate "Allow Remote Send" and remote port-control consents govern cloud writes and remote open/close/reconfigure. Data uploads only while someone is watching and counts toward the monthly traffic quota
• Account system: Sign in / sign out from the Account submenu under File, with a "keep me signed in" persistent session; the status bar shows the account state on the far right and menu entries follow the auth state
• Device binding & account sync: Bind this machine to your account after signing in and keep account data in sync
• Auto-reconnect: Automatically attempts to reconnect after an unexpected disconnect
• Send-frame checksums: Outgoing frames can carry a checksum, with a quick-settings entry
• Receive find/filter bar: The receive text area gains a find/filter bar for locating content in large outputs

• Toolbar rework: Regrouped by function with connection controls first; toggle buttons now reflect their pressed state; shortcuts completed; the port combo stays in sync across windows and defaults to a real available port; the toolbar is locked in place
• Menu rework: Added a Connection menu, moved Account under File, consolidated licensing entries; completed Simplified Chinese translations with unified mnemonics
• Registration dialog: Redesigned the registration/purchase prompt; the defunct Weidian QR code is replaced with a direct purchase link
• Network error dialogs: Friendlier, easier-to-understand error messages

• Terminal passthrough double space: Fixed spaces being sent twice in terminal passthrough mode
• .spu session loading: Port selection and console binding are restored correctly when loading a .spu file
• Document modification tracking: Unsaved changes are flagged correctly; fixed stale state after New and the current file path being overwritten
• Internationalization: Repaired several English source strings and Chinese translations; disambiguated Port labels across contexts

• 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

• 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
