[PNG] Thoughts on semver-ish naming? "Third Edition" -> 1.3

Hello everyone,

Currently, we are calling it PNG Third Edition. This follows the previous
naming convention.

Many of us in this group lean more towards engineering, which will bias us
on form vs. function. But if we put on our marketing hats for a bit, I want
to discuss naming and how it might help with adoption.

Think about HTML5 and CSS3.

People know about it. They know there have been updates. They can then look
into the updates and get excited about them. That excitement also assists
in adoption as users want the new features. If the users don't know, they
can't.

I believe this would also help in adoption if we eventually make breaking
changes and move to 2.0. There are already some useful features we want to
add but they would be a large enough change that they likely will cause
adoption problems. And it will be difficult to explain "This program
supports PNG Fourth Edition, but that program only supports PNG Third
Edition".


JPEG XL is an example of why I'm concerned about this. JPEG XL is an
amazing advancement. But despite its technical advantages, it is facing an
uphill battle on adoption. I think people would agree that it is good that
the web has advanced with HTML5 and CSS3. It is a shame that image
advancement seems to face more hurdles.

I am not a marketing expert. JPEG XL seems like a better name than say
"JPEG Fifth Edition" (making up that number). And even still, it faces
adoption headwinds. With my limited expertise here, I speculate that
JPEG5 would have made it feel like a more natural thing to adopt. But I do
not know that for sure.


If we do like the idea of 1.3 instead of "Third Edition" (and eventually
2.0), there is another topic to discuss:
First Edition would have been 1.0. Second Edition would have been 1.1. That
means Third Edition would be 1.2, not 1.3.

I could be wrong, but I think 1.2 & "Third Edition" takes a split second of
hesitation that lends towards silly mistakes. And even though 1.3 would be
wrong, I think it removes that hesitation.


Do you all have thoughts on favoring numbered versions over "Third Edition"
wording?
And do you have thoughts on 1.2 vs. 1.3?
Further, does anyone have marketing connections to help us here?

Thanks!
