Was digging through a project at work today where some guy in 2014 made 100+ commits in a single day and the only one that had a comment said "upgrading to v4.0".
brief description
- change1
- change2
<reference to issue, if applicable>
I add the issue number since most decent issue trackers with integrated VCS (ie, github, bitbucket + jira) will automatically hyperlink it to the actual issue
