-## 📦 What's New
+## 📦 What's New in v1.1.0
 
-This is the **initial stable release** featuring:
+### 🆕 Major Feature: Multi-Python Version Detection
 
-- ✅ Automatic virtual environment detection (`.venv`, `venv`, `env`, `.env`)
-- ✅ Safe package uninstallation with confirmation
-- ✅ Automatic pip upgrade
-- ✅ Base packages installation (setuptools, wheel)
-- ✅ Clear console interface with progress indicators
-- ✅ Error handling and helpful hints
+When operating on the global environment, the tool now:
+
+- ✨ **Auto-detects all Python installations** using both `where python` and Python Launcher (`py -0p`)
+- 🎯 **Smart selection**: Auto-uses the only version if just one is found
+- 📋 **Interactive choice**: Shows a numbered list when multiple versions exist
+- ✅ **Input validation**: Ensures you pick a valid version number
+- 🔒 **Precise control**: Reset only the Python version you actually want
+
+### 🔧 Technical Improvements
+
+- All pip operations now use `python -m pip` for version-specific execution
+- Enhanced script reliability with delayed variable expansion
+- Automatic deduplication of detected Python paths
+- Improved error handling throughout the script
+
+### 📈 Growth
+
+- Script expanded from 197 to 333 lines (+68% for better functionality)
+- Added comprehensive documentation in CLAUDE.md
+- Updated bilingual README with detailed usage scenarios
 
 ## 💡 Perfect For
 
 - Cleaning up messy virtual environments
-- Troubleshooting package conflicts  
+- Managing multiple Python versions on your system
+- Troubleshooting package conflicts
 - Starting fresh without recreating venv
-- Testing clean installations
+- Testing clean installations across different Python versions
 
 ## ⚠️ Safety Features
 
 - **Global environment protection** - Requires typing `YES` to operate on system Python
+- **Version confirmation** - Shows selected Python path and version before proceeding
 - **Multiple confirmations** - Shows package list before uninstalling
 - **Non-destructive** - Doesn't delete the venv folder itself
 
+## 📖 Example Workflow
+
+### With Virtual Environment (Unchanged)
+```batch
+# Your venv is detected automatically
+> env-reset.bat
+检测到虚拟环境: .venv
+当前 Python 环境: C:\Project\.venv\Scripts\python.exe
+# Continues normally...
+```
+
+### With Multiple Python Versions (NEW!)
+```batch
+> env-reset.bat
+# No venv detected, shows warning
+真的要操作全局环境吗？(输入大写 YES 确认): YES
+
+检测到以下 Python 版本:
+------------------------------------------
+[1] C:\Users\User\AppData\Local\Programs\Python\Python312\python.exe
+    Python 3.12.0
+[2] C:\Users\User\AppData\Local\Programs\Python\Python311\python.exe
+    Python 3.11.5
+------------------------------------------
+
+请选择 Python 版本 [1-2]: 1
+
+已选择: C:\Users\User\AppData\Local\Programs\Python\Python312\python.exe
+Python 3.12.0
+# Continues with selected version...
+```
