Because I noticed a simple mistake right after sending v1
—I forgot to include the version number and changelog for v2—
so I thought that by fixing it without waiting for reviewers to point it
out, 
I could save reviewers' time and get the patch merged more quickly.
 I may have been wrong about that. Sorry.
