On this question: https://answers.atlassian.com/questions/1574/enable-commit-comments-in-activity-stream

I entered as my answer: "You can also see all of the commit activity across all of your projects by going to the Source tab activity stream: https://yourinstance.jira.com/source/changelog"

but the HTML it's outputting is a little bit mangled:

<p>You can also see all of the commit activity across all of your projects by going to the Source tab activity stream: <a href="https://yourinstance.jira.com/source/changelog%3C/p" rel="nofollow">https://yourinstance.jira.com/source/changelog</p</a>>

Notice the mis-nested </a> at the end.
