Don’t get too excited thinking it’s a major new release because it’s called 5.0 instead of 4.22.
It’s just that the major bump in the version number gives the impression that there might be a huge number of major new changes but that’s not the case here.
I’d like to point out (yet again) that we don’t do feature-based releases, and that “5.0” doesn’t mean anything more than that the 4.x numbers started getting big enough that I ran out of fingers and toes.Linus Torvalds
Of course, it doesn’t mean Kernel 5.0 doesn’t have new features. In fact, the “overall changes for all of the 5.0 release are much bigger.”
New features in Linux Kernel 5.0
Here are some of the major new changes in Kernel 5.0:

Getting Linux Kernel 5.0
Some rolling release distributions like Arch Linux will start to provide Kernel 5.0 in a few days (or hours perhaps). Check your Linux kernel version and see if it’s already updated to the new kernel with the last system update.
But most other distributions like Ubuntu, Linux Mint, Fedora, Debian etc won’t provide this release anytime soon (or ever).
If you really want to use the new kernel, you may try Ukuu. It’s a GUI tool that lets you easily install other kernel versions. The older versions of the tool are still free and open source but you need to buy licenses for the newer version, unfortunately.
This article was originally published earlier and anticipated Kernel 5.0 release in summer’18. Linux Kernel 5.0 was actually supposed to be released after 4.19. But apparently, a few people really liked to see the Linux Kernel 4.20 purely for the number 4.20. Pun intended.
