Sub-task issue does not reflect Sprint changes

If parent issue Sprint is changed, the information about this is displayed in the issue changelog and sub-task sprint is also updated, but for sub-task neither history or updated date reflect this change.

eazyBI reporting plugin for JIRA is going through issue history to reflect Sprint changes for issues (including sub-tasks). In the case when sub-task Sprint is updated, eazyBI has no way of detecting what was the previous sprint or that the issue was updated at all (as the updated date is not changing for sub-task if it's Sprint is changed).

It would be necessary that sub-tasks are processed in the same way as other issues

• In case sub-task Sprint is changed, this information is reflected in sub-task changelog (history tab) the same way as for parent issue types
• sub-task updated date is changed when the Sprint of sub-task is updated
