I understand and thank you for contributing.
A release is the tarfiles and that is fixed. In git a release is a series of
hashes or tags or both across a number of repos. The issue with this approach is
the layering of another number and interface onto the deployment so a user's
tools or scripts would need to match the version and dot to the tarball they are
using. I user will tend to just fetch the new dot point tarball and build.
I originally had the RSB as a single repo for all releases at once but it became
clear this model was never going to work and Sebastian made a case for it to be
branched in each release and kept in a linear manner on each release branch. It
was the right choice then and I believe it continues to be the right choice. I
see this change as a half step back.
Thank you for the idea and the input.
Chris
