+## 1.9.0 - 2026-09-21
+
+### English
+
+#### Added
+
+- Added live Markdown editing: focus a paragraph or inline expression to edit its source while retaining the document view, selection and undo history.
+- Added Kimi Code recognition, session commands and managed notification hooks.
+- Added cloud backup controls with saved preferences, connection feedback and access to configuration backups.
+- Added a persistent font-ligature setting that applies to open terminal sessions.
+
+#### Fixed
+
+- Fixed Codex cold restoration using a Hook group identifier instead of the native conversation identity. Saved sessions with an older or unrecognized transcript filename retain their existing valid conversation ID.
+- Fixed file-editor selections and search matches blending into light and dark backgrounds. Ordinary text/code files now reveal the configured workspace background image, and the caret row follows the active theme.
+- Fixed copying the terminal working directory: menu and command-palette actions copy the directory reported by the shell, including guest paths, while normal selection copying retains the original text.
+- Fixed AI failure and cancellation events being presented as successful completion; Pi retry-aware outcomes and Claude failure events use the shared notification result handling.
+- Fixed WSL hook installation and event delivery using the distribution's own user configuration. Updated command completions include the distribution and user options.
+- Fixed inherited Ctrl+C suppression preventing interruption of CMD child commands, while keeping selection copying available.
+- Fixed native CMD command activity and multiline/pending-wrap input tracking.
+- Fixed application 256-color blocks being overwritten by terminal prompt colors. Explicit custom color overrides remain supported.
+- Fixed SSH automatic authentication ignoring the available system agent.
+- Fixed long Markdown outline headings overlapping neighboring rows.
+
+#### Improved
+
+- Added direct responses for supported AI confirmation notifications, with stale-request checks before sending a response; Windows notification activation restores the corresponding application window.
+- Made notification duration configurable and preserved the selected duration when replacing a pane's result.
+- Reduced repeated Git/SVN drawer work by reusing repository snapshots and rendering visible rows.
+- Improved settings search, SSH connection cards and terminal file-link opening.
+
+Windows packages include an installer and portable ZIP. Linux and macOS packages retain their Preview designation. This candidate is intended for installation testing; visual acceptance and live cold restoration with every external CLI remain separate from automated checks.
+
+### 中文
+
+#### 新增
+
+- 新增 Markdown 即时编辑：聚焦段落或行内表达式即可编辑对应源码，同时保留文档视图、选区和撤销历史。
+- 新增 Kimi Code 识别、会话命令和受管理的通知 Hook。
+- 新增云端备份入口，支持保存偏好、连接反馈和访问配置备份。
+- 新增可持久保存的字体连字设置，并可应用于已打开的终端会话。
+
+#### 修复
+
+- 修复 Codex 冷恢复误用 Hook 分组标识而非原生对话身份的问题。旧快照中的会话文件名无法识别时，保留原有有效对话 ID。
+- 修复文件编辑器选区与查找命中融入浅色、深色背景的问题；普通文本和代码文件可透出已配置的工作区背景图，光标所在行跟随当前主题。
+- 修复终端工作目录复制：菜单和命令面板复制 Shell 上报的目录，包括访客环境路径；普通选区复制保留原始文字。
+- 修复 AI 失败和取消事件被显示为成功完成的问题；Pi 重试后的结果及 Claude 失败事件统一进入通知结果处理。
+- 修复 WSL Hook 安装与事件传递，使用发行版自身的用户配置；命令补全同步包含发行版和用户选项。
+- 修复继承的 Ctrl+C 忽略状态导致 CMD 子命令无法中断的问题，同时保留选区复制。
+- 修复原生 CMD 命令活动、多行输入和等待折行边界的输入跟踪。
+- 修复应用的 256 色块被终端提示符颜色覆盖的问题，保留明确配置的自定义颜色覆盖。
+- 修复 SSH 自动认证忽略可用系统代理的问题。
+- 修复 Markdown 目录长标题与相邻行重叠的问题。
+
+#### 改进
+
+- 支持从部分 AI 确认通知直接回答，发送前检查请求是否过期；Windows 通知激活时恢复对应的应用窗口。
+- 支持配置通知停留时长，并在替换窗格结果时保留选定时长。
+- 复用仓库快照、仅渲染可见行，减少 Git／SVN 抽屉的重复工作。
+- 改进设置搜索、SSH 连接卡片和终端文件链接打开。
+
+Windows 提供安装器和 ZIP 便携包，Linux 和 macOS 包继续标记为 Preview。本候选用于安装测试；视觉验收和所有外部 CLI 的实际关窗恢复仍需单独验证。
