关键摘要:

• 在T.MenuItem组件中新增了hoveredColor属性，但未看到对应属性的使用代码。
• 修改了T.MenuItem组件的color属性，使用了control.D.ColorSelector.hoveredColor，这可能是为了响应鼠标悬停事件。
• 移除了backgroundColor属性，如果这个属性是用于设置背景颜色的，那么移除可能会导致背景颜色不再更新。

是否建议立即修改:

• 是，需要确认新增的hoveredColor属性的用途，并确保移除backgroundColor不会对组件的行为产生负面影响。同时，应该检查是否有必要的注释说明这些更改的目的和影响。
