A new kernel-version policy for Ubuntu The Canonical Kernel Team has https://discourse.ubuntu.com/t/kernel-version-selection-for-ubuntu-releases/47007 a new policy regarding the version of the kernel that will ship with each Ubuntu release; the result will generally be the shipping of newer releases. To provide users with the absolute latest in features and hardware support, Ubuntu will now ship the absolute latest available version of the upstream Linux kernel at the specified Ubuntu release freeze date, even if upstream is still in Release Candidate (RC) status. The post goes on to acknowledge that "there are issues with this approach"; there are a lot of policy details that will apply depending on just how raw the shipped kernel is. https://lwn.net/Articles/985043/
