To allow us to automatically create a good quality changelog from our git history we recommend the following formats for commit messages.
The aim is to capture a reference to any ticket, card, or story that this commit contributes towards.
Because we are now using the Pivotal Tracker Webhook on some projects we suggest wrapping your commit message prefix with square brackets []
