From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

There is a distinction between regular updates and distribution upgrades. The latter have to be done manually. I know that distribution upgrades via GUI have been in the works; no idea if that is a thing yet.

As for what's missing: The most important thing to keep in mind is that fedora releases only get security updates for 1 year after release + some grace period depending on the date of the n+2 release.

Op is talking about Fedora not Ubuntu/Debian. This does not apply.
Poorly upgrades often only work manually. They are like dates, sometimes more happens, sometimes less, so they may be a bit random, but its good to wait a bit and then upgrade, as they introduce new possibly breaking changes. Meanwhile the old version (on Debian and Ubuntu even multiple ones) still get updates, mainly security fixes, but on Fedora I think there are none, so in a different way non-major updates
