[Cai Huoqing]

Fix typo:
*submited  ==> submitted
*becasue  ==> because
*idential  ==> identical
*trival  ==> trivial
*splitted  ==> split
*attributs  ==> attributes
*insted  ==> instead
*removeable  ==> removable
*unnecessarilly  ==> unnecessarily
*prefered  ==> preferred

v1->v2:
*revert the change of "iff" which means "if and only if"
*update changelog
