Well, it rather depends on nature of the patch doesn't it. Some are hard and some are easy. AFAIK the security team would be happy to receive and distribute additional backports to older versions done by community members e.g. those on the predisclosure list. > And a somehow more general thought: what most people expect from > baremetal hypervisors, I think, is stability.

Do you think we should do something other than bump the version when we cut a new release? or do you think we should add features to stable branches or something? The release cadence has been discussed on the list fairly recently. I would suggest you make your views known under that topic rather than here where people might miss it.
