In the release summary section, there is a report that counts requirements and test cases.
This count includes two categories:
1) Current requirements which still match the JQL in the requirements section.
2) Inactive requirements that no longer match the JQL (but did previously). ZE italicizes the inactive requirements in the requirements list.
Today the report counts both Current and Inactive requirements. The enhancement request would allow the user to see the total of Current requirements. One option could be to keep what displays today and add a section for Current only counts.
