Documentation for JIRA 4.2. Documentation for other versions of JIRA is available too.
JIRA's Change Log report shows resolved issues in the last ten released versions of a project. Whereas the Road Map looks forward, the Change Log looks back, giving an overall view of issues resolved in recent versions.
If your administrator has hidden the 'Fix For Version' field, the Change Log report will not be available.
