+
+#### 优化

+### 🇺🇸 English
+
+#### Features
+
+- Added a silent update check at startup. When a new release is found, the menu item changes to “New Version Available…”. The standard Sparkle update window appears only after the user clicks it; TypeSwitch does not automatically present UI, download, or install updates.
+
+#### Improvements
+
+- Unified menu wording for running, configured, and unavailable apps, the default rule, and switch statistics, and reorganized menu sections so rules and common actions are easier to scan.
+- Updated the English and Chinese READMEs, menu screenshots, and Homebrew tap trust installation guidance.
+
+#### Engineering
+
+- Added a pinned SwiftFormat setup, a repository-managed pre-commit hook, and required pull-request formatting and test gates.
