In JIRA 5, the first time a user logs in, a window appear with the message: What's new in JIRA 5. Users can disable this window, but the first time each user logs in, this message appears.

This behavior can result in a mixed content warning within JIRA running on HTTPS.

How to remove this message for every user that logs in the first time
