And this can also be used as a cross-reference for our upgrade docs. Anyways, sine for trunk / 2.7 we would only be rolling bouncible from 2.6 and not from others this is not a big point. We can leave it to another follow-up PR. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
