Our SVN Development/Release Process

I've been working with my team to create a new development and release process for our Moodle 2.x code.  We've been using SVN for a number of years, so we can save the SVN Vs. GIT argument until another date.  For now, this process is based on SVN. We developed a new two-week release process, in which every two weeks we have a new production release.  This makes our turn around time for releasing new features, bug fixes and enhancements quite quick, or at least quicker than it used to be.  I've created a graphic to show how our process works but that can actually be more confusing than me...
