* The widget `RadioButton` has a new initialization parameter `default` to control its default state
控件 `RadioButton` 新增初始化参数 `default` 来控制其默认的状态
* Experimental support for color strings in RGBA format has been added to the Color subpackage
颜色子包新增对 RGBA 格式的颜色字符串的实验性支持
🟣 **Fixed / 修复**
* Fixed an bug where the animation classes `MoveWidget` and `MoveComponent` were not moving objects to the correct position when they were called repeatedly
修复了动画类 `MoveWidget` 和 `MoveComponent` 在被反复调用的情况下无法将对象移动到正确位置的问题
* Fixed an bug where the animation class `ScaleFontSize` did not scale the font size correctly

🔵 **Optimized / 优化**
* Optimized the way to get the style file, the widget can set a relative name to reduce the amount of code, and the relative name starts with a decimal point
优化了样式文件的获取方式，小组件可以设置相对名称来减少代码量，相对名称以小数点开头
* The theme mechanism is optimized, there is no longer a need to write a tag in the style file, and the mapping relationship between the color parameters of the item and the keywords of the style file can be written in the definition of `Shape`, so as to reduce the redundant content in the style file and improve the compatibility between the style files
主题机制优化，样式文件中不再需要写出 tag，可在 `Shape` 的定义中写明 Item 的颜色参数与样式文件关键字的映射关系，以此缩减样式文件中的冗余内容，提高各样式文件之间的兼容性
* Optimized the appearance of some widgets
优化部分控件外观
* Improved cross-platform compatibility
提高了跨平台的兼容性
* Improved 3D submodule compatibility with the new version of `tkintertools`
提高了 3D 子模块对新版 `tkintertools` 兼容性
* Change the constants `FONT` and `SIZE` to dynamic values, so that font modifications can take effect globally
将常量 `FONT` 和 `SIZE` 改成动态取值，便于字体修改可以全局生效
🟡 **Changed / 变更**
* The animation class `Gradient` no longer converts an empty color string to black when it accepts it, but simply throws an exception
动画类 `Gradient` 在接受空颜色字符串时不再将其转化为黑色，而是直接抛出异常
* The implementation code for the 3D subpackage has been moved from file `three/__init__.py` to file `three/engine.py`
3D 子包的实现代码从文件 `three/__init__.py` 移动到了文件 `three/engine.py`
* The submodule `style` has been changed to the sub-package `style` and its contents have been reorganized
