The Acquia.com team migrated the site to GIT for version control. It has many layers of redundancy which means a slightly more complicated workflow than I've experienced. As I got a handle on the new workflow I picked up new skills and tools. First, I have a much better handle on what really happens when you work locally, push to the dev site and then move things to staging and production. Second, I have picked up a few new things in Git including, branch/master and checking them out, as well as merging my branch to master. A great tool I've been using for edits is Netbeans.
