No. But the even/odd thing is still so fresh in peoples memory (despite us 
not having used it for years), and I think some projects aped us on it, so 
if I didn't change the numbering setup, but just wanted to reset the minor 
number, I'd probably jump from 2.6 to 2.8 just for historical reasons.

But I could also see the second number as being the "year", and 2008 would 
get 2.8, and then next year I'd make the first release of 2009 be 2.9.1 
(and probably avoid the ".0" just because it again has the connotations of 
a "big new untested release", which is not true in a date-based numbering 
scheme). And then 2010 would be 3.0.1 etc..

Anyway, I have to say that I personally don't have any hugely strong 
opinions on the numbering. I suspect others do, though, and I'm almost 
certain that this is an absolutely _perfect_ "bikeshed-painting" subject 
where thousands of people will be very passionate and send me their 
opinions on why _their_ particular shed color is so much better.

The only thing I do know is that I agree that "big meaningless numbers" 
are bad. "26" is already pretty big. As you point out, the 2.4.x series 
has much bigger numbers yet.

And yes, something like "2008" is obviously numerically bigger, but has a 
direct meaning and as such is possibly better than something arbitrary and 
non-descriptive like "26".

Let the bike-shed-painting begin.

(I had planned on taking this up at the kernel summit, where the shed 
painting is at least limited to a much smaller audience, but since you 
asked..)

Offset 2000 version numbers

Here's my contribution to the bike shed: Offset 2000 Version Numbers.

Offset 2000 version numbers

When 2.6 becomes the next 2.4, after undergoing some transition to a time-based numbering
scheme, what then?

So 2010.01.01 represents the first release of "2.8" in 2010. A moment later some janitorial
release is made to what was once "2.6.x". How would that be numbered? I guess we could have an
addend of some sort again, but this seems to bring us back to where we started. Confused :)

Let's just drop the '.6' and carry on from where we are: in other words, 2.27.x, 2.28.x, 2.29.x and so on. At least we return to a 3-level number, and it increments neatly whilst retaining some vague meaning.
