+# 🛡️ Excalink Plugin v1.0.1 - Security & Quality Update
+
+## Release Overview
+
+Version 1.0.1 addresses critical security concerns and code quality improvements identified during the Obsidian Community Plugin review process. This update ensures the plugin meets all Obsidian plugin development guidelines.
+
+## 🔧 Bug Fixes & Security Updates

+### Security Enhancements
+
+- **🛡️ HTML Security**: Replaced all `innerHTML` usage with safe DOM API methods (`textContent`, `createEl()`)
+  - Fixed potential XSS vulnerabilities in `FrameSuggestModal.ts`
+  - Fixed HTML injection risks in `ExcalinkSettingTab.ts`
+  - All user content now safely rendered using Obsidian's DOM helpers
+
+### Styling Improvements
+
+- **🎨 CSS Refactoring**: Moved all inline styles to `styles.css` for better theme compatibility

+  - Better integration with Obsidian themes and user customizations
+
+### Performance Optimizations
+
+- **🚀 Console Cleanup**: Significantly reduced console logging to prevent dev console pollution
+  - Removed excessive debug statements that were active in production
