1.6.8 is a dud, and will never see the light of day. Thankfully, we found the problems with ra_serf and the deps during the testing, and appropriate fixes have been nominated.
My plan is to reroll 1.6.9, but holding the roll until r900797 (a high-impact bug fix), and the 1.6.x-1.6.8-serfassertion branch are approved or vetoed. If possible, please review these two issues. Thanks, -Hyrum
