I searching for a reliable way to track modifications to core code for web application code. Say for example I install Joomla. Then I make some changes to the core code, or install a plugin. I'm in need a system where I can record and track these modifications for my customer's sites so that others in our company can see what's been done, and better prepare for updates to those sites. Does such a system exist? Should I just use a local database?
My first by the way. T.I.A.
