Yesterday I ran apt-get update/upgrade and noticed that the bootloader and kernel were upgraded. Thinking this was a clue that a reboot would be required to run the new upgrades, I rebooted but found no change in the kernel (still at 4.4.50, #970 Feb.20). I tried apt-get dist-upgrade, rebooted and no change in kernel.
Shouldn't an upgraded kernel result in a version change?
