 ## 🔧 版本兼容性

 ### 支持的 Maya 版本
- **所有 Maya 版本** - 从 Maya 2016 到最新版本
+- **所有 Maya 版本** - 从 Maya 2016 到 Maya 2025+
+- **Maya 2025** - 完全兼容，修复了 PyMEL 相关问题

 2. **优雅降级** - PyMEL 不可用时自动使用 cmds
 3. **相对导入** - 支持作为包导入或独立模块使用
 4. **异常处理** - 完善的错误处理和用户提示
+5. **空值安全** - 处理节点无父节点等边界情况
+6. **Maya 2025 优化** - 修复 PyMEL 在新版本中的兼容性问题

 - 大量物体操作时会显示进度条
 - 权重文件使用 pickle 格式，不同 Python 版本间可能存在兼容性问题

+### Maya 2025 特别说明
+- 已修复 PyMEL 在处理无父节点骨骼时的 `'NoneType' object has no attribute 'name'` 错误
+- 增强了所有 PyMEL 对象的空值检查
+- 建议使用 `saveJointInfo=True` 导出完整的骨骼信息
