Completed upgrade testing using RC1 packages against a 4.1 cluster.
Things hold up fine. (replicate type volumes)
I have not attempted a rolling upgrade of disperse volumes, as we still
lack instructions to do so. @Pranith/@Xavi is this feasible this release
onward?
There were some problems with optimistic-change-log option. I think that disabling it before upgrading (and give some time to become effective) makes it possible to successfully complete a rolling upgrade, but I've not tested it personally.
Adding @Ashish Pandey who tested it, and may know more details about the procedure.
