Hi Francesco ,

    Thank-you for this update.  The dead nodes are in a uat environment
so can likely wait until the next release. Perhaps we can then upgrade
all environment from 2.7.1 to current with this feature.

Does a move from 2.7 to 2.8  on all nodes require just the rpm to be
replaced, or is there any additional configuration due to differences in
releases?   ( Please reply with just search the rabbitmq site if it is
on there and I missed it).

Cheers,S
