A common situation is in a product/project with many issues is that some issues will be indirectely fixed in a previous release - though not testet at the time. It would therefore be more correct to move the issues as resolved/closed in a previous released release/sprint instead of keeping them in the current release/sprint.
Kan Jira/Greenhopper acomodate this (preferably without un-releasing a released release if possible).
Thanks!!
