A few things I'd like us to follow with regards to using JIRA:
* Create a JIRA for all changes/fixes/improvements - unless they have no effect on users
* When completing an issue mark as resolved (not closed) - we'll close when we do a
release (otherwise we can't change fix version without re-opening the issue)
A few things for Git:
* Try to keep it to a single commit per-JIRA
* Refer to JIRA issue in the commit message
