[...] 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. -- Without deviation from the norm, progress is not possible.
