v1.7.0

What's Changed

New Features

• X11 forwarding for SSH connections. Run Linux GUI applications remotely and display them on your local machine. Windows builds bundle VcXsrv X Server with no extra components needed; macOS requires XQuartz (brew install --cask xquartz). Enable the toggle in the SSH connection form's advanced settings.
• X11 desktop support. Launch full Linux desktop environments (GNOME, KDE, XFCE, MATE, Cinnamon, Openbox) over SSH with X11 forwarding. A new x11-desktop session type with standalone SSH credentials and auto-launched X Server.
• VNC Require TLS toggle, shared session mode, and VNC Repeater ID support.
• S3 connections now support virtual-hosted–style endpoints (e.g. Alibaba Cloud OSS, Tencent COS, Huawei OBS).
• Telnet negotiation mode, local echo, send mode (character/line), newline mode (CR/CRLF), and character encoding options for compatibility with diverse telnet servers.
• Serial port connections now use the unified connection form (same as all other protocols) instead of a standalone dialog, with new support for character encoding, local echo, and newline mode.
• Per-connection backspace key option for SSH, Telnet, Serial, and Mosh sessions. Choose between ASCII Delete (DEL, 0x7F), ASCII Backspace (BS, 0x08), or VT220 Delete. Default changed from DEL to Backspace (^H) for out-of-the-box compatibility with Huawei, H3C, Cisco network gear and serial consoles.

Improvements

• xterm.js upgraded to 6.0.0 with all addons (search, fit, ligatures, Unicode 11, clipboard). (@coderstory)
• JetBrains Mono Variable font bundled as the default monospace font, replacing the previous system font stack. (@coderstory)
• Terminal text highlighting no longer highlights inside code fences or full code blocks, avoiding false positives in AI output and markdown. (@coderstory)
• Extensive performance and stability hardening across all subsystems: store (atomic writes, debounced I/O, sharded sessions), session (larger read buffers, event-driven flush loops, lock contention reduction), frontend (rAF-coalesced rendering, memoized computations, ring buffer for session data), K8s (HTTP transport tuning, cached parsing, watch/log reconnect with backoff), AI/LLM (SSE streaming buffers, shared HTTP client, typed event payloads), sync (async init, ETag conditional GETs, AES-GCM AAD binding), and database (connection pool tuning, parallel schema loading, identifier escaping). (@coderstory)
• Configurable terminal double-click word separator. Choose which characters act as word boundaries for double-click selection in terminal settings. (@wangxufeng)
• Refined the built-in uniTerm Dark and uniTerm Light terminal theme colors.
• macOS DMG now split into separate amd64 and arm64 packages instead of a universal binary, avoiding compatibility warnings on macOS 26+.
• Connection remark field for adding free-form notes to any connection.
• Redesigned database and MongoDB natural-language query layout: the NL input now sits to the left of the SQL/filter editor at matching height, with the generate button styled like the Execute button for better discoverability.

Bug Fixes

• Fixed cursor blink setting not persisting across restarts. (@wangxufeng)
• Fixed Claude Code and other TUI glyphs not rendering after terminal history restore. (@coderstory)
• Fixed AI CancelChatStream race condition that could leave stale cancellations across overlapping requests. (@coderstory)
• Fixed sync security: enforced file whitelist, improved password mismatch handling, removed hostname leak from config. (@coderstory)
• Fixed K8s auth not retrying on 401, watch/log streams not reconnecting after transient failures. (@coderstory)
• Fixed database connection pool race, query timeout handling, and SQL Server resource cleanup. (@coderstory)
• Fixed monitor trend chart colors not resolving CSS variables, causing invisible chart lines.
• Fixed container commands (docker/nerdctl) flashing a console window on Windows.
• Fixed K8s node operations: added confirmation prompts before cordon/uncordon and corrected the drain icon.
• Fixed macOS Caps Lock swallowing the first letter typed after toggling on macOS 26/27 beta. (@surenwuyuwuqiu)
• Fixed legacy SSH servers failing to connect due to missing CBC/3DES ciphers and hmac-sha1-96 MAC algorithms.
• Fixed terminal history recording reliability: restored bottom-up prompt scanning for compatibility with diverse shell prompts. Added independent AI transcription toggle so users can keep history suggestions while turning off AI-powered command rewrites.
• Fixed X11 forwarding failure on macOS when DISPLAY is empty (e.g. app launched from Finder/Dock) by probing /tmp/.X11-unix. (@surenwuyuwuqiu)
• Fixed SSH jump-host tunnel not working for terminal sessions. (@wangxufeng)
• Fixed AI sidebar allowing messages to be sent without an active terminal session, causing failed messages to persist in conversation history and later be sent to the LLM as valid context. The input box and send button are now disabled when no terminal panel is associated.
• Fixed NL-to-SQL prompt not including the currently selected table name, so the AI had no context about which table the user was viewing.

Notes

• As this open-source software has not purchased a code-signing certificate, the unsigned executable may trigger false positives in some antivirus engines (e.g. Windows Defender). This is a known issue with Go/Wails applications (see wailsapp/wails#3308). You can add an exclusion rule in your antivirus to allow it. Please download only from the official open-source channels — GitHub and Gitee. If you are still concerned about malware, you can download the source code and build and run it locally yourself.

更新内容

新功能

• SSH X11 转发。在 SSH 连接表单高级设置中开启后，可运行 Linux 远程 GUI 应用并在本地显示。Windows 版本内置 VcXsrv X Server，无需额外安装组件；macOS 需安装 XQuartz（brew install --cask xquartz）。
• X11 桌面支持。通过 SSH X11 转发启动完整 Linux 桌面环境（GNOME、KDE、XFCE、MATE、Cinnamon、Openbox）。新增 x11-desktop 会话类型，独立 SSH 凭据，自动启动 X Server。
• VNC 连接新增 TLS 开关、共享会话模式和 VNC Repeater ID 支持。
• S3 连接支持虚拟主机风格端点（如阿里云 OSS、腾讯 COS、华为 OBS）。
• Telnet 协商模式、本地回显、发送模式（字符/行）、换行模式（CR/CRLF）、字符编码选项，提升与不同 Telnet 服务器的兼容性。
• 串口连接统一使用标准连接表单（与其他协议一致），不再使用独立弹窗；新增字符编码、本地回显、换行模式支持。
• SSH、Telnet、Serial、Mosh 连接新增退格键选项：可选 ASCII Delete（DEL, 0x7F）、ASCII Backspace（BS, 0x08）或 VT220 Delete。默认值由 DEL 改为 Backspace（^H），兼容华为、H3C、Cisco 网络设备及串口控制台。

改进

• 内置 JetBrains Mono Variable 字体作为默认等宽字体，取代之前的系统字体栈。（@coderstory）
• 终端文本高亮不再匹配代码块（code fence）内的内容，避免 AI 输出和 markdown 中的误高亮。（@coderstory）
• 全面性能与稳定性加固：store（原子写入、防抖 I/O、会话分片）、session（更大读缓冲、事件驱动刷新循环、减少锁竞争）、前端（rAF 合并渲染、缓存计算、会话数据环形缓冲）、K8s（HTTP 传输调优、缓存解析、watch/log 断线重连与退避）、AI/LLM（SSE 流缓冲、共享 HTTP 客户端、类型化事件负载）、sync（异步初始化、ETag 条件 GET、AES-GCM AAD 绑定）、database（连接池调优、并行 schema 加载、标识符转义）。（@coderstory）
• 终端双击选词分隔符可配置。在终端设置中可自定义哪些字符作为单词边界。（@wangxufeng）

• 修复 SSH 跳板隧道对终端会话不生效的问题。（@wangxufeng）
• 修复 AI 侧边栏在无终端关联时仍可发送消息的问题，导致失败消息残留在对话历史中并被后续发送给 LLM 作为有效上下文。现在无终端面板关联时输入框和发送按钮自动禁用。
• 修复 NL-to-SQL 提示词不含当前选中表名，AI 无法感知用户正在操作哪张表的问题。

说明

• 由于本开源软件未购买代码签名证书，未签名的可执行文件可能被部分杀毒引擎（如 Windows Defender）误报拦截。这是 Go/Wails 应用的已知问题（参见 wailsapp/wails#3308）。可在杀毒软件中为其添加排除规则以放行。请务必从 GitHub、Gitee 官方开源渠道下载软件。如仍担心存在病毒，可自行下载源代码在本地构建运行。
