Today I needed to figure out when a certain setting (DisablePrint – funnily enough disables print in the OnTime Group Calendar Notes UI’s) was added to OnTime Group Calendar and I just couldn’t remember. So how would I find out? No way was I going to do diffs all the way back through all my tags. A bit of googling and voila! – git log to the rescue. Using a combination of git log and git tag I was able to find out in a couple of minutes. Besides being very cool and an excellent display of the power of git it also highlight just why meaningful commit messages are very important as they give you this option to go back through the log and figure out when stuff was added.
