+# 更新日志
+
+本文档记录 ashell 的重要功能变更。
+
+格式参考 [Keep a Changelog](https://keepachangelog.com/zh-CN/1.1.0/)，版本号遵循
+[语义化版本](https://semver.org/lang/zh-CN/)。
+
+## [v0.5.0] - 2026-08-27
+
+### 新增
+
+- 支持 ANSI 转义序列中的 F1–F12 功能键映射，解决在终端工具（如 `htop`、`mc`、`vim` 等）中按 F1–F12 无法响应的问题 (#91)。
+- 连接管理新增分组功能，支持创建分组、重命名、删除分组、折叠展开与按组归类管理连接 (#108)。
+- 扩展终端通知协议支持，兼容 OSC 9、OSC 99、OSC 777 和 BEL (响铃)，支持 macOS Dock 与 Windows 任务栏未读徽标，后台标签页显示闪烁提醒，点击通知可自动唤醒窗口并切换至对应标签页 (#110)。
+- 新增系统级应用菜单，提供包含关于、文件、编辑、视图、窗口和帮助等常用操作 (#111)。
+
+### 变更
+
+- 重新设计侧边栏连接管理交互：侧边栏头部增加显式的“编辑 / 完成”模式切换按钮，编辑模式下在搜索框下方提供全宽“+ 新增分组”按钮，并移除侧边栏右下角切换 Switch 开关。
+- 优化侧边栏连接项点击体验：非编辑模式下点击整行即可直接发起连接并隐藏冗余外链图标；允许侧边栏宽度自定义拖拽调小至 200px。
+- 将 CSV 导入与导出入口位置由侧边栏头部整合移至设置对话框的“配置文件与备份”页面中。
+- 优化标签栏加号下拉菜单：将第二个菜单项更新为“打开连接”，点击后直接弹出连接选择器对话框。
+- 支持侧边栏完全折叠隐藏，折叠后隐藏连接列表并最大化终端界面绘制区域。
+
+### 修复
+
+- 修复 SSH 历史命令输入时的残留字符与光标定位偏差问题 (#114)。
+- 优化 Windows 平台下终端拖拽与窗口细节表现 (#112)。
+
+### 兼容性与稳定性
+
+- 代码架构模块化重构：将核心代码拆分为 `session`、`terminal`、`app`、`backend`、`sftp` 与 `sync` 模块，提升可维护性 (#105-#107)。
+- 优化 GitHub Actions CI 构建工作流 (#109)。
+
+### 注意事项
+
+- CSV 导出的密码为明文格式，请妥善保管并在迁移后及时删除导出的 CSV 文件。

+## 🚀 v0.4 Major Upgrades
 
-The brand-new v0.3 introduces comprehensive upgrades to both architecture and user experience:
+v0.4 builds on the v0.3 foundation and focuses on more capable workspace operations and a smoother daily workflow:
-- ✨ **Global Real-Time Font Settings** (Thanks to [@ancion](https://github.com/ancion) for [PR #6](https://github.com/rust-kotlin/ashell/pull/6)): Customize your global UI fonts and terminal rendering fonts independently. Adjust text size in real-time with automatic persistence.
+- ✨ **Keybinding Management**: View and edit common shortcuts from the settings UI with conflict hints.
-- ✨ **Concurrent SFTP Transfers**: A dedicated Transfers dialog now supports highly optimized, concurrent file uploads and downloads with precise progress display.
+- ✨ **Settings Page Polish**: A more compact and clearer settings experience with improved layout and interaction flow.
-- ✨ **Persistent Workspace State**: Your sidebar width adjustments, terminal themes, font settings, and file visibility preferences are completely restored upon your next launch!
+- ✨ **Multi-Pane Tabs with a tmux-like Workflow**: A single tab can now host multiple panes, with split, focus, and switching actions for a tmux-inspired experience.
-- ✨ **Intelligent SSH Disconnect/Reconnect**: Greatly enhanced SSH connection resilience. Provides a beautiful and localized overlay for one-click re-connection on unexpected disconnections.
+- ✨ **Transfer History Improvements**: The transfer history panel now presents richer task details, making upload and download activity easier to review.
-- ✨ **Hot-Swappable i18n System**: Deeply optimized internationalization. Switch instantly between English and Simplified Chinese without restarting the application.
+- ✨ **SSH Passphrase Support**: Private keys can now store a passphrase, and SSH connections will use it automatically.
-- ✨ **Smart Right-Click Actions**: Added intelligent right-click copy and paste for the terminal, featuring a dedicated settings toggle and OS-native keyboard shortcut hints.
+- ✨ **Terminal Rendering Enhancements**: Terminal rendering now handles Block Elements and similar custom glyphs more completely.
 
 ## Download
 
-You can download the latest pre-compiled releases for macOS, Windows, and Linux from the [GitHub Releases page](https://github.com/rust-kotlin/ashell/releases/latest).
+You can download the latest installers from the [GitHub Releases page](https://github.com/rust-kotlin/ashell/releases/latest):

+- macOS: `.dmg` installers for x64 and arm64, plus portable `.zip` archives.
+- Windows: `Setup.exe` installers for x64, x86, and arm64, plus portable `.zip` archives.
+- Linux: a portable x64 `.tar.gz` archive.
 
 ## Mac Installation Guide
 
-After downloading, please unzip the file and move `ashell.app` to your **Applications** folder. 
+### Method 1: Homebrew (Recommended)
-Since the app uses ad-hoc signing, macOS may warn that the app is "damaged" upon first launch. If this happens, open Terminal and run the following command:
+
+If you use [Homebrew](https://brew.sh/), you can install it quickly with:
+
+```bash
+brew install rust-kotlin/taps/ashell --cask
+```
+
+To update the app:
+
+```bash
+brew update
+brew upgrade ashell --cask
+```
+
+> **Note**: Since the app uses ad-hoc signing, the Homebrew installation or update includes a postflight script to automatically handle the quarantine flag. This will require you to enter your administrator password for authorization.
+
+### Method 2: Manual Download
+
+1. Download the `.dmg` matching your processor from the [Releases page](https://github.com/rust-kotlin/ashell/releases/latest).
+2. Open the DMG and drag `ashell.app` into **Applications**.
+3. Since the app uses ad-hoc signing, macOS may warn that the app is "damaged" upon first launch. If this happens, open Terminal and run:
 
 ```bash
 sudo xattr -cr /Applications/ashell.app
 ```
 
+## Windows Installation Guide
+
+Download the appropriate installer from the [Releases page](https://github.com/rust-kotlin/ashell/releases/latest):
+
+| System architecture | Installer suffix |
+| --- | --- |
+| Intel/AMD 64-bit | `windows-x64-setup.exe` |
+| Intel/AMD 32-bit | `windows-x86-setup.exe` |
+| Windows on ARM | `windows-arm64-setup.exe` |
+
+The installer can optionally create a desktop shortcut and registers ashell in the Start menu and the Windows uninstall list.
+The installer is not yet signed with a commercial code-signing certificate, so Windows SmartScreen may display a security warning.

+## Codex and Terminal Completion Notifications
+
+ashell supports generic OSC 9 completion notifications. For Codex CLI, add the following to
+`~/.codex/config.toml`:
+
+```toml
+[tui]
+notifications = ["agent-turn-complete", "approval-requested"]
+notification_method = "osc9"
+notification_condition = "unfocused"
+```
+
+When an eligible notification originates in the background or a non-visible tab, ashell shows a
+native notification and a flashing bell on the corresponding tab. Unread notifications also add a
+red badge to the macOS Dock icon or a red overlay to the Windows taskbar icon. Clicking the native
+notification activates ashell and switches to the originating terminal tab; viewing that tab clears
+its unread state. No reminder is shown when ashell is active and the notification originates in the
+currently visible tab. An unselected tab shows a loading indicator beside its title for two seconds
+after receiving terminal output. Continued output refreshes the indicator, while the selected tab
+does not show it.
+
+You can test a generic OSC 9 notification with:
+
+```bash
+printf '\033]9;Task completed\007'

 ## Mac 安装指南
 
-下载并解压后，请先将 `ashell.app` 拖入或移动到 **应用程序 (Applications)** 目录。
+### 方法 1: Homebrew 安装 (推荐)
-由于应用采用本地签名，初次启动时如果系统提示“App 已损坏，无法打开”，请打开终端（Terminal）并执行以下命令：
+
+如果您使用 [Homebrew](https://brew.sh/)，可以通过以下命令快速安装：
+
+```bash
+brew install rust-kotlin/taps/ashell --cask
+```
+
+更新应用：
+
+```bash
+brew update
+brew upgrade ashell --cask
+```
+
+> **注意**: 由于应用采用本地签名，Homebrew 在安装或更新过程中会执行一个后置脚本来自动处理隔离属性（quarantine flag），这需要您输入管理员密码以授权。
+
+### 方法 2: 手动下载
+
+1. 从 [Releases 页面](https://github.com/rust-kotlin/ashell/releases/latest) 下载与处理器匹配的 `.dmg`。
+2. 打开 DMG，将 `ashell.app` 拖入 **Applications** 目录。

+## 终端通知与任务提醒
+
+ashell 支持 [OSC 9](https://iterm2.com/documentation-escape-codes.html)、
+[OSC 99](https://sw.kovidgoyal.net/kitty/desktop-notifications/)、
+[OSC 777](https://wezterm.org/escape-sequences.html) 和终端响铃（BEL），通知能力不绑定
+Codex 或其它特定工具。只要 CLI、脚本或远程程序发送受支持的终端控制序列，本地终端、
+SSH 和串口标签页都会将其转换为 macOS 或 Windows 系统通知，无需修改工具配置或伪装
+其它终端。
+
+OSC 9 携带通知正文；OSC 777 和 OSC 99 可以同时携带标题与正文，OSC 99 还支持
+`always`、`unfocused` 和 `invisible` 显示时机。BEL 本身不含正文，因此仅显示通用提醒，
+不会读取或推断当前终端画面中的内容。
+
+符合显示时机的通知来自后台或非当前可见标签时，ashell 会显示系统通知，标签按钮以
+闪动铃铛标记未读状态，并在 macOS Dock 或 Windows 任务栏图标上显示红色徽标。点击
+系统通知会激活 ashell 并切换到对应的终端标签，查看对应标签后自动清除未读状态。
+如果应用已激活且通知来自当前可见标签，则不重复提醒。未选中的标签在最近 2 秒内收到
+终端输出时，会在标题左侧显示 Loading 动画；持续输出会刷新显示时间，当前标签不会显示。
+
+可以分别使用下面的命令测试四种提醒：
+
+```bash
+sleep 3; printf '\033]9;Task completed\007'
+sleep 3; printf '\033]777;notify;Deploy;Production is ready\033\\'
+sleep 3; printf '\033]99;i=ashell-test:d=0;Build completed\033\\'; printf '\033]99;i=ashell-test:p=body;Artifacts are ready\033\\'
+sleep 3; printf '\007'
+```
+
+执行后在 3 秒内切换到其他应用。macOS 第一次收到通知时可能会询问权限；如果仍未显示，
+请在“系统设置 > 通知 > ashell”中确认已允许通知。
