Keeping track of changes

Finding a bugs' origin can be really annoying at times and quite often bugs are introduced by recent releases. In order to easily keep track of what happened when (mostly releases), we introduced a "timeline":

As you can see this timeline is simply a large sheet of paper where we write down date, time and a short description of the change, be it a release or an activated feature. This way, when a bug comes up, we can easily look up, if the error started on the date of the change, raising the odds to find the bug quickly.
