I just remember how things were last time i used anything with YUM on it, trust me the more you keep it maintained the better.
Even if you dont see a update make sure the repos are refreshed at least once every two weeks at maximum.
I mean yeah in many respects CentOS doesnt get big huge updates like say Manjaro does, its more like debian where you dont always get the latest version of things.
But that doesnt mean its insecure, far from it as even debian keeps up to date if there is something serious like a needed update to the kernel or firefox.
This is more of a downstream type of update cycle, there patches from future versions of the system are sent down and checked for compatibility and then put into the OS.
This is what makes both CentOS and Debian so stable.
Compare that to something like Arch linux where everything is upstream, latest packages and versions but far more breakages.
Then you have something that is a little more in between such as Ubuntu or Linux mint, where you can make both update upstream if you wanted to.
This is why I like linux so much as you can make it update on your own terms (depending on your distro of course) rather than the whims of some company that make updates on their terms.
Granted this is better then it was as i remember how lazy Microsoft was back in the XP days, you rarely got big security patches now its far more regular which is one of the few things I actually like about windows 10.
Actually in a way Windows 10 has a very similar style of updating that a rolling release of linux does.
But its more like Manjaro than arch.
Manjaro (what i use a lot of the time) does have smaller package updates but every so often there is a big update that changes the kernel and the main libraries of the OS.
For something like manjaro you dont need to be as attentive as you do in CentOS (ironic as its rolling) but the more you keep it updated the better as the longer you dont update it the more packages it will give you.
Manjaro is a very special case as you can install older "versions" of it but you will always be able to update, Manjaro uses its versions as more of a snapshot of the OS though and not a new version.
Its like a photo in time, you take a photo one month and that nice new building is all fresh and clean... take a photo a few years later and hey someone sprayed graffiti on it! its always good to have a fresh snapshot of Manjaro.
Compare this to the way say ubuntu releases and its a totally different animal.
Ubuntu is also a special case as not only can you run it as stable for 5 years but there are point releases and new versions every 6 months and a new LTS every 2 years.
Ubuntu has a very unique system of upgrades, one can swing from version to version if they wished or go from LTS to LTS.
For Ubuntu the latest LTS is 18.04 however the next version is in October and that will be Ubuntu 18.10
For ubuntu users this means if they want to they can upgrade to the latest and greatest but this comes with the caveat that ubuntu 18.10 will only be supported for 9 months.
This means in that time they must update to 19.04 or be unsupported or go back to 18.04 if 19.04 doesnt work.
But 19.04 will have a 9 month lifespan as well, so will ubuntu 19.10 but 20.04 will have a 5 year lifespan as it will be LTS
The ubuntu version numbers are a indicator of how this all works, 18.04 is not the 18th version of ubuntu it only came out in 2018.
18 is the year and 04 is the month (April)
Ubuntu 18.10 will release in October of 2018
Then will come 19.04 In april of 2019 but it will not be LTS, then comes 19.10 also wont be LTS
But 20.04 will be LTS
So to sum it up:
18.04 = LTS, 18.10, 19.04, 19.10 = Not LTS, 20.04 = LTS
