Zorin Version Numbers - What determines them?

Hello. New Zorin user. I wanted to try Pop OS, but ended up on Zorin because it's easier and it recognizes most of my hardware out of the box! So, that's a win for me!

Anyway, I was wondering about the version numbers. Looking at the history, I noticed the numbers tend to be inconsistent, especially since there's no Zorin version between 12.4 and 15.

(Hopefully, it's not related to triskaidekaphobia)

So, I was wondering what a point release (16.2 for example) consists of vs a whole release (17 for example). Like, when they update the base to the newest one, would that be 17 or would it be 16.2?

I'm just curious.

Zorin OS has released editions numerically that follow to higher numbers throughout.
However... early on, ZorinGroup released a "Limited Edition '09" and in the following years, another special edition was released.
That threw the numerical scheme off by Two Editions, so when ZorinGroup started development on Zorin OS 15, they decided to reset the count to the actual number of editions, rather than having the many numerical editions plus two special editions.
This added "two" to the count, bumping Zorin OS 13 up to Zorin OS 15.

Point releases, like Zorin OS 12.4 or 16.1 are Major Upgrade releases that happen Within the same LTS Base Build.
Full releases are editions which have a newer LTS base build. For example Zorin OS 15 is based on Ubuntu 18.04. Zorin OS 16 is based on Ubuntu 20.04.

To the best of my knowledge, numerology and a fear of the number thirteen were not involved in the above decisions.


With my experience before coming a new version windows then coming also a new version Zorin. That my experiences.

Okay. So, should the next version be 17 based on the fact that Ubuntu released another LTS?

Yes, 17

Who know what version it will be ?
We don't know what will be in future next version Zorin then how we know the version Zorin will be a 17?

We know because the ZorinGroup has said so:

Version "jump":

Wait, what happened to Zorin 13 & 14?
As the previous stable release of Zorin OS was version 12 you might be wondering where versions 13 and 14 went.
Well, don’t panic: you didn’t miss them. Zorin’s lead developer explains why there’s a small ‘jump’ in version number for this release:
“The reason is that this is actually the 15 version of Zorin OS. In between Zorin OS 1.0 and 2.0 way back in 2009, we released a version called “Limited Edition ’09” [so] we decided to take the opportunity to correct the version number with this release.”
