It seems like we are mixing up two different concepts here, one being
"major/minor" and another one being "stable/unstable". I don't think the
"stable/unstable" concept applies to Tails as all releases have the same
lifetime and are ready for production. We don't have the opposite
concept of "development release".

Since we don't have this concept of stability in Tails it sounds more
logical to me to translate "stable=important" into "major=important".
Important releases being granted even number (such as 1.0).

I read bits of the Wikipedia article on software versioning and
understood what you were referring to:

- The Linux kernel, used between 1.0 and the 2.6.x "odd minor version
numbers to denote development releases and even minor version numbers to
denote stable releases".
- GNOME which uses even for major and odd for development as well.

I feels to me than using "even" for the more important releases and
bigger milestones, thus puts us more in sync with GNOME that doing it
otherwise for example. And makes it more logical to call Tails Jessie
2.0 without workarounds you described.

But I won't fight over it more than that :)
