我想知道关于“可为 null 的类型”具体是在哪一个版本中新增加的功能，在文档中并没有写，我在componentProps.ts文件中查看类型 PropType 的最近一次修改是在 75c8cf6 ，所以它是在 v3.5.0-alpha.1 之后增加的新功能吗？如果是的，那么能否在文档中用徽章标记出来？

I wonder exactly what version of Nullable Type was added in, it wasn't written in the docs, I looked at the type in the componentProps.ts file The last modification of the type PropType was in 75c8cf6, so is it a new feature added after v3.5.0-alpha.1? If so, can it be marked with a badge in the document?
