You can rescan a previously scanned application's version in order to find out what changed between the previous version and your new version.

The easiest way to start a rescan is to go to the scan summary of your previously scanned version and to click on the "Rescan" button.

It will direct you to the procedure of starting a new scan of this application and pre-select the previously scanned version as parent scan.

Here, you can select any previously performed scan of this application as a parent. By default, the latest scan is used as parent but also earlier scans can be selected.

The parent's analysis results will be used to compare the new analysis results to.

More information about this can be found in the parent comparison documentation.
