This latest library release-set includes several fixes. Having the
lastest version installed always suppose an extra effort for the users.
Moreover, bumping the dependencies is also a way to force packagers to
upgrade.

The libraries are backward compatible. We did not break the API nor ABI
so that users with the own applications are not forced to upgrade.

The thing changes if we discuss about the userspace tools. I think that
they must use the latest library release. Thus, we avoid having people
that report problems that has been already fixed.

The gcc warning is anecdotic, it was not the main reason to bump the
dependencies.

Looking at the current state of the libraries, I think that it's the
best for now. Later on, once they get more stable and well-tested, we
may change this policy.
