Comparing Issues Between Revisions

Use issue comparison to see which issues are new, remediated, or unchanged between two revisions of a project or release group.

2 min readUpdated Jul 9, 2026

Overview

Issue comparison lets you compare the issues in your current revision against an older revision, so you can see at a glance which issues are new, which have been remediated, and which are unchanged. It provides a snapshot of issue scan results across licensing, quality, and security scans within FOSSA.

Getting started

Issue comparison is available for both project and release-group scopes, including existing projects and release groups. It uses the same issues table as the standard issues view, so you can filter, sort, and action on issues directly from the comparison view.
