 ## Changelog
 
+### v0.9.1
+
+**New Feature: Image Output Mode**
+
+- Added `OUTPUT_MODE` configuration parameter with two options:
+  - `html` (default): Interactive HTML mind map with full control panel
+  - `image`: Static SVG image embedded directly in Markdown (uploaded to `/api/v1/files`)
+- Image mode features:
+  - Auto-responsive width (adapts to chat container)
+  - Automatic theme detection (light/dark)
+  - Persistent storage via Chat API (survives page refresh)
+  - Efficient file storage (no huge base64 strings in chat history)
+
+**Improvements:**
+
+- Implemented robust Chat API update mechanism with retry logic
+- Fixed message persistence using both `messages[]` and `history.messages`
+- Added Event API for immediate frontend updates
+- Removed unnecessary `SVG_WIDTH` and `SVG_HEIGHT` parameters (now auto-calculated)
+
+**Technical Details:**
+
+- Image mode uses `__event_call__` to execute JavaScript in the browser
+- SVG is rendered offline, converted to Blob, and uploaded to OpenWebUI Files API
+- Updates chat message with `/api/v1/files/{id}/content` URL via OpenWebUI Backend-Controlled API flow
