Are there change-logs of the kernel somewhere?
The 2.x kernels I mainly toyed with include 2.6.18 and 2.6.32 (CentOS 5 and 6, respectively) - especially on OpenVZ virtualization nodes: https://download.openvz.org/kernel/ - granted there weren't huge differences between these two.
One of the greatest (and much needed) features of the 4 series is the ability to perform kernel updates without rebooting. I relied on third party products to do this in the past, and still do for the majority of my servers (namely, Ksplice and KernelCare) - I come across an overwhelming of systems that are compromised at the root-level, which could have easily been prevented if the administrator were to have installed a kernel update - but the convenience isn't so widely available in Linux ~4.00 - due to the need to reboot.
Elsewhere, there's improved hardware support - nothing too magical here though.
As for the changelogs, here's a nice place for those: http://kernelnewbies.org/LinuxVersions
