The current Jira Macro has the ability to show Jira Issues.
Customers may need to retrieve other information from Jira and use it to populate pages in Confluence.
I couldn't find any Confluence plugin nor a Jira Gadget that could populate Jira Project releases in a Confluence Page.
The more Atlassian applications are seamlessly connected, the more the customers will have a better experience.

Request Summary

• In a Confluence Page, show Jira Software Project releases in a similar view as we have in Jira.
• This could be a Jira Macro similar to what we have for Jira Issues.
• In Jira, the view is accessible through link <Jira URL:port>/projects/<project name>?selectedItem=com.atlassian.jira.jira-projects-plugin:release-page&<other filters>
• An example of the Releases Page of a test project in a test Jira server is shown below.
  

Currently Workaround

• Use an iframe into an HTML Macro with a code similar to what have below.
  Example of an iFrame to display Jira Project Releases page

  <iframe src="http://quicksilver/jira/projects/DY68705?selectedItem=com.atlassian.jira.jira-projects-plugin%3Arelease-page&status=all" noborder="0" width="830" height="800" scrolling="yes" seamless> </iframe>
  

• The main problem with this workaround is that we can have page loading problems when Jira is sending clickjacking security headers, aside that it is not seamlessly connected.
