Rather than simply stating "Bug Fixes" in the release, could you explicity state which bugs were fixed for a particular build, along with a brief description of each one?
Or if you think that would clutter the "changes" file to much, could you make a link on the EAP download page to a common JIRA report/summary detailing the same?
Changes --> Shows basic text file
Bugs Fixed --> Shows bugs fixed in JIRA
If you can make the ITN login SSO with JIRA, that would be great also. (Im going to add this to the JIRA comments thread)
