Hello.

	Seeing this email and from the working groups phone call shows a lot of
confusion over what is supported or maintained. So for the last few days
I stepped backed and asked why is everyone confused. What this shows is
lack of explaining to the community what a maintenance and a feature
release are and how they differ. Also the version scheme is not well
defined. 
	First lets define a maintenance branch. The maintenance branch is
defines as the branch where no new features are added during its life
time. A features branch is one that new improvements are introduced for
validation but will not be supported for general production use and bug
fixes will not be incorporated.
	Currently for the 2.X branches we have 

2.1.X - maintenance branch
2.2   - feature branch
2.3   - feature branch

	So here is my proposal to end this confusion. For maintenance branches
we start a new number i.e for the next one it would be 3.0.0.
At the same time another branch, 3.1 be open for more features. In other
words 3.0.0 and 3.1 would be branched off the same root branch but
evolve in different ways. Yes for 2.X is a bit different due changes in
companies with 2.0 and 2.1.

3.0.0   - maintenance branch
  3.0.1
  3.0.X
3.1.0   - features branch
  3.1.1
  3.1.X
3.2.0   - features branch
  3.2.1
  3.2.X
4.0.0   - maintenance branch 

	I just hope that the 3.0 branch would open up after the 2.3.
