After a JSON import in the Control Panel, you can now see exactly which findings it affected. A new View Imported Findings link appears in the import progress panel once the import completes.
View Imported Findings: Opens the findings list filtered to only the findings that import created or updated, the same way the CSV import summary does.
Consistent tagging: The JSON import now tags affected findings the same way CSV imports do, with the source file name and import time, so you can find them again later from the Tags filter.
