I'm honestly not sure how the 0.7.0-M1 version got there, but I can guess: the development version is 0.7.0-SNAPSHOT. But when Josh suggested cutting a new version this time, he suggested the 0.6.1 (the previous stable was 0.6.0). I can talk to him about changing it to 0.7.0, if you'd feel better about it. ;~)
