Well, I don't know I am only a contributor after all:
1) But do some one or some ones clearly mentioned [1]
2) Per-version change history must be placed below the '---' separator.
    The required format is 'Changes in vN:'. Custom formats are not
    acceptable.

So v1->v2 is considered as a valid format and not a custom format.
Hum, interesting.

What a wonderful world =]

Appreciated all the "reviewers" HAHA :D
