Keeping the Framework for Your Application Up to Date with Git

I recently started building a web application using the Laravel Framework. But, since I was building the application in my spare time, and a new version of Laravel was being released each week, I knew the version of the framework I started with would not be the same when I finished. Conundrum: I needed a simple way to stay on top of any security, bug, or feature related updates, without having to download and drag and drop folders.
