Jira Custom Report Using Release Status

[Chris Loe]

This may be a stupid question, however I want to generate a custom report for all issues, where the release has been completed. I cannot find either Release Status or Release date in the list of custom report fields. Have they been named something obscure, have I just missed it or is this simply not possible?

You could use the JQL function in ReleasedVersions()

fixversion in ReleasedVersions()

and you can limit the search results to the releases of a single project like this:

fixversion in ReleasedVersions(ProjectX)
