I want to create a release overview on a Confluence page using the JIRA Issue/Filter macro. For this, I need a JQL statement that generates a list of versions.

How can I request a list of released version using JQL?

Sure, I can search for JIRA issues which have been release with a specific version e.g. fixVersion in releasedVersions(projectname), but how can I get a list of these versions itself using JQL?

All my research, including in the Atlassian forums, has only shown ways of how I can search for issues associated with versions.
