Please don't rush multiple versions, if your previous version is buggy
you have to reply to it saying so and then wait before posting v2.

Reviewing something just to find there is a v2 already posting is one
of the more annoying experiences for maintainers and reviewers.

Quoting documentation:

  Resending after review
  ~~~~~~~~~~~~~~~~~~~~~~

  Allow at least 24 hours to pass between postings. This will ensure reviewers
  from all geographical locations have a chance to chime in. Do not wait
  too long (weeks) between postings either as it will make it harder for reviewers
  to recall all the context.

  Make sure you address all the feedback in your new posting. Do not post a new
  version of the code if the discussion about the previous version is still
  ongoing, unless directly instructed by a reviewer.
