+# Changelog
+
+## [2.1.0]
+
+### English
+<!-- gpm:lang en -->
+
+GoPieMenu now supports English, Traditional Chinese, and Simplified Chinese. New configurations follow the system language by default, falling back to English for unsupported languages. You can choose a language in Settings; apply the change and restart the app for it to take effect. Menu edits still require an explicit Apply, and unapplied changes are handled before the app exits.
+
+#### What's new
+
+- Chinese interfaces use Microsoft JhengHei UI. Changing language offers Later or a blue Restart button; Restart saves all pending edits first.
+- Manual launches show the editor, including when already running. Windows autostart stays in the tray.
+
+- GoPieMenu checks for stable releases automatically at startup. When an update is available, it shows a tray notification if the window is hidden or a dialog if the window is open.
+- Release notes appear in the current UI language, with English used when a translation is unavailable.
+- Skip a release to stop being notified about that version.
+- Download the installer and verify its SHA256 checksum. Before installation, confirm the update and resolve any unapplied edits; GoPieMenu then exits so the installer can run.
+
+<!-- gpm:endlang -->
+
+### 繁體中文
+<!-- gpm:lang zh-TW -->
+
+GoPieMenu 現在支援英文、繁體中文與簡體中文。新設定預設依照系統語言顯示，不支援的語言則使用英文。你也可以在「設定」中選擇語言，套用後重新啟動應用程式生效。選單編輯仍須明確按下「套用」，結束應用程式前也會處理尚未套用的變更。
+
+#### 新功能
+
+- 中文介面使用微軟正黑體 UI。切換語言會提供「稍後」與藍色「重新啟動」按鈕，重新啟動前會套用所有待存變更。
+- 手動開啟會顯示編輯器，已在背景執行時也會喚回；Windows 自動啟動則留在系統匣。
+
+- GoPieMenu 會在啟動時自動檢查穩定版更新。若有更新可用，視窗隱藏時會顯示系統匣通知；視窗開啟時則會顯示對話方塊。
+- 發行說明會以目前介面語言顯示；若缺少該語言的翻譯，則改用英文。
+- 可以略過某個版本，之後不再收到該版本的通知。
+- 下載安裝程式並驗證 SHA256 校驗碼。安裝前請確認要更新，並處理尚未套用的變更；接著 GoPieMenu 會結束，讓安裝程式執行。
+
+<!-- gpm:endlang -->
+
+### 简体中文
+<!-- gpm:lang zh-CN -->
+
+GoPieMenu 现在支持英语、繁体中文和简体中文。新配置默认跟随系统语言显示，不支持的语言则使用英语。你也可以在“设置”中选择语言，应用后重启程序生效。编辑菜单仍需明确点击“应用”，退出应用前也会处理尚未应用的更改。
+
+#### 新功能
+
+- 中文界面使用 Microsoft JhengHei UI。切换语言会提供“稍后”与蓝色“重新启动”按钮，重新启动前会应用所有待保存更改。
+- 手动打开会显示编辑器，已在后台运行时也会唤回；Windows 自动启动则留在系统托盘。
+
+- GoPieMenu 会在启动时自动检查稳定版更新。如果有可用更新，窗口隐藏时会显示系统托盘通知；窗口打开时则会显示对话框。
+- 发布说明会以当前界面语言显示；如果没有对应语言的翻译，则使用英语。
+- 可以跳过某个版本，之后不再收到该版本的通知。
+- 下载安装程序并验证 SHA256 校验和。安装前请确认更新，并处理尚未应用的更改；随后 GoPieMenu 会退出，以便运行安装程序。
+
+<!-- gpm:endlang -->
+
+<!-- gpm:lang shared -->
+### Validation
+
+The local Release build and all seven CTest entries passed, including core and update regression tests, release-note extraction, and UI tests at 100%, 125%, 150%, and 200% scaling. Deployed startup with the SDK removed from PATH, TLS backend loading, and installer packaging also passed.
+
+Language tests cover Later, save-before-restart, save failure, and launch failure at all four scales. A deployed process also passed the wait-for-parent restart check. Update tests use simulated network responses and installer launches. Actual Windows sign-in startup, notification delivery, and an elevated installation remain manual acceptance checks.

+
+## [2.0.0]
+
+### English
+<!-- gpm:lang en -->
+
+GoPieMenu 2.0 rebuilds the menu editor around a live preview, independent profile appearance, and an explicit Apply/Discard workflow.
+
+#### What's new
+
+- Edit actions directly from the pie preview. Switch profiles without losing drafts, and use Undo/Redo before applying changes to the running menu.
+- Arrange actions by dragging an entire row, with insertion markers, edge scrolling, and selection preserved. Right-click preview or organizer actions to duplicate or delete them.
+- Customize each profile independently: presets, size, colors, opacity, and animation. Duplicating a profile copies its appearance without linking later edits.
+- Choose colors with a hue ring, saturation/value square, HSV/opacity controls, RGB/RGBA hex input, and recent colors.
+- Use a searchable icon picker with asynchronous loading and embedded icons. Custom SVG, PNG, JPEG, and ICO files remain supported.
+- Combine Ctrl, Shift, Alt, and Win modifiers independently with mouse triggers. Keyboard recording keeps the selected activation mode.
+- Save empty actions as placeholders; triggering them does nothing.
+- Enjoy a refreshed light editor, consistent dialogs and tray menu, new application artwork, and custom window controls.
+
+#### Upgrading from 1.0
+
+1. Export your configuration from Settings, then quit GoPieMenu from the tray before running the installer.
+2. Download and run `GoPieMenu_Setup.exe` from this release. This is the Windows x64 installer; Qt dependencies are included.
+3. Open Settings, review your profiles, and use **Apply** to save changes. Closing the editor hides it to the tray; quitting prompts about unapplied edits.
+
+The configuration location and version 1.0 JSON format are retained. Existing appearance values and supported legacy style keys are preserved. Appearance edits now affect only the selected profile. Choose **Frost** to opt into the new, nearly opaque preset. Invalid configurations are reported without overwriting the original file; import is an undoable draft operation.

+
+GoPieMenu 2.0 重新打造選單編輯器，提供即時預覽、各設定檔獨立的外觀，以及明確的「套用／捨棄」流程。
+
+#### 新功能
+
+- 直接在圓餅預覽中編輯動作。切換設定檔時草稿會保留；套用至執行中的選單前，可以使用復原／重做。
+- 拖曳整列即可排列動作，並提供插入標記、邊緣捲動且保留選取狀態。在預覽或整理清單中的動作上按右鍵，即可複製或刪除。
+- 為每個設定檔獨立自訂外觀：預設樣式、大小、顏色、不透明度與動畫。複製設定檔時會一併複製外觀，之後的編輯則彼此獨立。
+- 使用色相環、飽和度／明度方塊、HSV／透明度控制項、RGB/RGBA 十六進位輸入及最近使用的顏色來選色。
+- 使用可搜尋的圖示選擇器，支援非同步載入與內嵌圖示。仍可使用自訂 SVG、PNG、JPEG 與 ICO 檔案。
+- 滑鼠觸發方式可各自搭配 Ctrl、Shift、Alt、Win 修飾鍵。錄製鍵盤快捷鍵時會保留已選的啟用模式。
+- 可以將尚未設定的動作儲存為佔位項目；觸發這類項目不會執行任何操作。
+- 編輯器改用清爽明亮的外觀，並統一對話方塊與系統匣選單樣式，加入全新應用程式圖示及自訂視窗控制按鈕。
+
+#### 從 1.0 升級
+
+1. 在「設定」中匯出設定，然後先從系統匣結束 GoPieMenu，再執行安裝程式。
+2. 下載並執行此版本中的 `GoPieMenu_Setup.exe`。這是 Windows x64 安裝程式，已包含 Qt 相依元件。
+3. 開啟「設定」並檢查各設定檔，然後按下「套用」儲存變更。關閉編輯器會將它隱藏至系統匣；結束程式時會詢問如何處理尚未套用的變更。
+
+設定檔位置與 1.0 版 JSON 格式維持不變，既有外觀值及支援的舊版樣式索引鍵也會保留。外觀變更現在只會影響選取的設定檔。選擇 **Frost** 即可使用全新且接近不透明的預設樣式。遇到無效設定時會顯示錯誤，不會覆寫原始檔案；匯入設定則會建立可復原的草稿。

+
+GoPieMenu 2.0 重新打造了菜单编辑器，提供实时预览、各配置独立的外观，以及明确的“应用/放弃”流程。
+
+#### 新功能
+
+- 直接在饼形菜单预览中编辑操作。切换配置时草稿会保留；应用到正在运行的菜单前，可以使用撤销/重做。
+- 拖动整行即可排列操作，并提供插入标记、边缘滚动且保留选中状态。在预览或整理列表中的操作上单击右键，即可复制或删除。
+- 为每个配置单独自定义外观：预设样式、大小、颜色、不透明度和动画。复制配置时会一并复制外观，后续编辑则互不影响。
+- 使用色相环、饱和度/明度方块、HSV/不透明度控件、RGB/RGBA 十六进制输入和最近使用的颜色来选色。
+- 使用可搜索的图标选择器，支持异步加载和内嵌图标。仍可使用自定义 SVG、PNG、JPEG 和 ICO 文件。
+- 鼠标触发方式可分别搭配 Ctrl、Shift、Alt、Win 修饰键。录制键盘快捷键时会保留已选的激活模式。
+- 可以将尚未设置的操作保存为占位项；触发这类项目不会执行任何操作。
+- 编辑器采用清爽明亮的新外观，并统一对话框和系统托盘菜单样式，加入全新应用图标及自定义窗口控制按钮。
+
+#### 从 1.0 升级
+
+1. 在“设置”中导出配置，然后先从系统托盘退出 GoPieMenu，再运行安装程序。
+2. 下载并运行此版本中的 `GoPieMenu_Setup.exe`。这是 Windows x64 安装程序，已包含 Qt 依赖项。
+3. 打开“设置”并检查各配置，然后点击“应用”保存更改。关闭编辑器会将其隐藏到系统托盘；退出程序时会询问如何处理尚未应用的更改。
+
+配置文件位置和 1.0 版 JSON 格式保持不变，已有外观值及受支持的旧版样式键也会保留。外观更改现在只会影响选中的配置。选择 **Frost** 即可使用全新且近乎不透明的预设样式。遇到无效配置时会显示错误，不会覆盖原始文件；导入配置会创建可撤销的草稿。
+
+<!-- gpm:endlang -->
+
+<!-- gpm:lang shared -->
+### Validation
+
+The release workflow runs core tests and UI tests at 100%, 125%, 150%, and 200% scaling, then checks that the deployed application starts without the Qt SDK on PATH before compiling the installer. `SHA256SUMS.txt` contains the installer's checksum.
+
+Real input behavior in individual applications, interactions between Win-key combinations and Windows system shortcuts, elevated applications, and moving between monitors with different physical scaling settings remain manual verification areas.

 The application and [tray menu](resources/demo/TrayMenu.png) use the new Pie Menu artwork and light styling. The GitHub button beside **About** opens this project's repository.
 
+## Updates
+
+GoPieMenu checks for newer stable GitHub releases at startup. A visible editor shows an update dialog; when hidden or minimized, a tray notification opens the same dialog. **Skip this version** remembers that release; **Settings → Check for updates** can revisit it.
+
+Release notes use the current interface language, with English fallback and shared validation information. **Update** downloads the Windows installer and verifies `SHA256SUMS.txt`. **Install and exit** asks you to resolve unapplied edits, then opens the Windows installer permission prompt. Cancelling that prompt keeps GoPieMenu running. Closing the update dialog with **Later** does not install anything.
+
+The [changelog](CHANGELOG.md) is the source for all release notes. Publishing a version extracts only its section into the GitHub Release body, which the application reads. Preview and smoke-test modes do not check for updates.
