git multiple-projects branching
===

In my case, The super project is big enough so it consists of multiple artifacts. Let's say project A,B,C,D,E. They are different git projects. Now we need to work on two different releases, then it comes down to the problem how do we wanna do branching. I am coming from subversion world initially, if it's SVN, I would probably think about creating a super project and contain all the sub projects A,B,C,D,E, then I just branch away the super project.

But in terms of branching, conceptually, git has some difference from SVN. Just wondering in git world, normally what's the best practice for branching multiple git projects for different releases? I know submodules has been talked a lot, does it make sense to branch the projects individually? 

Another question is that if the branching is done, how do we version the artifacts in different branches? if you have two branches, that will mean you will have different versions for all sub projects in two different branches, then you start to smell failure.
