+# Changelog
+
+## [1.0.1] - 2025-09-23
+
+### Fixed
+- **Index-Label Correspondence**: Fixed the issue where index and label were not properly matched in the dropdown menu
+- **Dropdown Order**: Corrected the dropdown menu to display labels in their original input order instead of alphabetical order
+- **Workflow Migration**: Resolved the issue where label states and counts were lost during workflow migration between machines
+
+### Technical Improvements
+- Modified `write_labels_to_file` function in `__init__.py` to preserve original input order
+- Improved filtering logic to only remove empty and whitespace-only strings
+- Enhanced data integrity during workflow serialization/deserialization
+
+## [1.0.0] - Initial Release
+- Basic Switch Any node functionality
+- Dynamic label input system
+- UI refresh button integration
+- JSON-based label persistence

 ## Features
 
+- **Clean Initial State**: New nodes start completely empty with no preset data, ready for custom configuration.
 - **Dynamic Label Inputs**: Start with a single label input. As you fill them in, new empty inputs appear automatically after a refresh.
 - **UI Refresh Button**: A **"Save & Refresh UI"** button is included directly on the node. This saves your current labels and reloads the ComfyUI interface in one click, updating the dropdown menu and input fields instantly.
 - **No Data Input**: This node is purely for routing and does not take any data inputs. It only outputs the selected `index` (INT) and `label` (STRING).
 - **Persistent Labels**: Your list of labels is saved in a JSON file within the node's directory, so they persist across ComfyUI sessions.
+- **Order Preservation**: Labels maintain their original input order in the dropdown menu, ensuring consistent index-label correspondence.
+- **Workflow Migration**: All label states are fully preserved when migrating workflows between different machines.

 2.  **Define Labels**:
     - Initially, you will see one input field, `label_1`. Enter a name for your first route (e.g., "SDXL").
     - To add more labels, you can fill in the next available input field (`label_2`, etc.).
+    - **Note**: Labels are processed in the exact order they are entered, maintaining index-label correspondence.
 3.  **Save and Refresh**:
-    - Click the **"Save & Refresh UI"** button on the node.
+    - Click the **"Save & Refresh UI**" button on the node.
     - The page will automatically reload.
 4.  **Select a Label**:

 ## 功能特性
 
+- **干净的初始状态**: 新节点完全为空，不包含预设数据，可进行自定义配置。
 - **动态标签输入**: 从一个标签输入框开始。当您填写后，刷新界面即可自动出现新的空输入框。
 - **UI 刷新按钮**: 节点上直接集成了一个 **"Save & Refresh UI"** 按钮。一键即可保存当前所有标签并重新加载 ComfyUI 界面，即时更新下拉菜单和输入框。
 - **无数据输入**: 这是一个纯粹的路由节点，不接收任何数据输入。它只输出所选的 `index` (整数) 和 `label` (字符串)。
