+# Release Notes
+
+## [1.1.1] - 2026-06-22
+
+### 🐛 Fixes
+
+- **Tab Closing on Duplicate Prevention** – Fixed bug where Prevent Tab Duplication was closing sidebar views and local graphs
+  - Sidebar panels (Outline, File Properties, Backlinks) no longer affected
+  - Local graph, graph, and other auxiliary views now properly excluded
+  - Only actual document tabs (markdown/file views) are now colored and managed
+
+---
+
+## [1.1.0] - 2026-06-19
+
+### ✨ Features
+
+- **Prevent Tab Duplication** – New settings toggle to prevent opening duplicate tabs of the same file
+  - When enabled, opening an already-open file will focus on the existing tab instead of creating a duplicate
+  - Particularly useful for maintaining clean workspace organization alongside colored tabs
+
+### 🐛 Fixes
+
+- **Settings UI Fallback** – Added robust fallback renderer for older Obsidian versions
+  - Ensures settings page renders correctly across all Obsidian versions ≥ 1.13.0
+  - Fixes blank settings page issue on environments that don't consume the new settings API
+
+### 📚 Documentation
