-## 🚀 v0.3 Massive Update!
+## 🚀 v0.4 Major Upgrades
 
-The brand-new v0.3 introduces comprehensive upgrades to both architecture and user experience:
-- ✨ **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.
-- ✨ **Concurrent SFTP Transfers**: A dedicated Transfers dialog now supports highly optimized, concurrent file uploads and downloads with precise progress display.
-- ✨ **Persistent Workspace State**: Your sidebar width adjustments, terminal themes, font settings, and file visibility preferences are completely restored upon your next launch!
-- ✨ **Intelligent SSH Disconnect/Reconnect**: Greatly enhanced SSH connection resilience. Provides a beautiful and localized overlay for one-click re-connection on unexpected disconnections.
-- ✨ **Hot-Swappable i18n System**: Deeply optimized internationalization. Switch instantly between English and Simplified Chinese without restarting the application.
-- ✨ **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.
+v0.4 builds on the v0.3 foundation and focuses on more capable workspace operations and a smoother daily workflow:
+- ✨ **Keybinding Management**: View and edit common shortcuts from the settings UI with conflict hints.
+- ✨ **Settings Page Polish**: A more compact and clearer settings experience with improved layout and interaction flow.
+- ✨ **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.
+- ✨ **Transfer History Improvements**: The transfer history panel now presents richer task details, making upload and download activity easier to review.
+- ✨ **SSH Passphrase Support**: Private keys can now store a passphrase, and SSH connections will use it automatically.
+- ✨ **Terminal Rendering Enhancements**: Terminal rendering now handles Block Elements and similar custom glyphs more completely.

 - **System Telemetry:** Real-time visualization of CPU, memory, swap, network, and disk metrics in the left cockpit sidebar.
 - **Theming System:** Switch between multiple GPUI Component themes directly from the top toolbar.
 - **Embedded Fonts:** Uses embedded Maple Mono NF CN fonts out-of-the-box for excellent CJK character and Nerd Font icon support.
+- **v0.3 Core Enhancements:** Global font and font-size controls, concurrent SFTP transfers, persistent layout state, disconnect awareness, hot-swappable i18n, and smart terminal right-click copy/paste.

-- ✨ **多语言热切换增强**：深度优化的 i18n 系统，包含中文与英文在内的所有界面文案现在均支持热切换。
-- ✨ **智能右键快捷操作**：新增终端右键智能复制与粘贴功能，提供专属设置项自由控制开关，并支持根据不同操作系统自适应显示原生快捷键提示。
+v0.4 在 v0.3 打下的基础上，重点带来了更完整的工作区操作能力和更顺手的日常体验：
+- ✨ **键位管理功能**：支持在设置中可视化查看和修改常用快捷键，并提供冲突提示。
+- ✨ **设置页优化**：设置页的布局和交互更加紧凑顺手，整体信息层级更清晰。
+- ✨ **Tab 内多 Pane 与类 tmux 体验**：一个 tab 内现在可以管理多个 pane，支持分屏、聚焦和切换，提供更接近 tmux 的工作流。
+- ✨ **传输历史增强**：传输历史面板展示更完整的任务信息，便于回溯上传和下载过程。
+- ✨ **SSH passphrase 支持**：现在可以为私钥填写 passphrase，并在连接时自动使用保存的口令。
+- ✨ **终端显示优化**：终端渲染进一步增强，支持 Block Elements 等自定义图形字符的更完整显示。
