Please give people a chance to review your series without having to
jump to the new one within 48 hours. If anything, it actively prevents
people from reviewing it (why would I review it, since the author is
going to post a new version in a couple of days...).
Also, given that we're >this< close to the next merge window, I don't
think this series is likely to be a candidate for 6.17. Give yourself
the space to polish the series and look at it with a critical eye,
there is plenty of time for 6.18.
Thanks,
M.
