After this upgrade, I now get the following error when trying to view the Version Control tab:
"Error rendering 'com.atlassian.jira.jira-cvs-plugin:cvs-tabpanel'"
I'm sure this is related to the CVS opensource plugin I had to use since JIRA stopped supporting CVS after version 6.1. Does anyone have any idea how to get CVS working again, other than the "Purchase Fisheye" answer?
