The SonarQube platform provides differential analysis, which allows users to track changes in project quality over time. The feature is available since SonarQube 5.3 and offers multiple views and drilldown capabilities to analyze code coverage, violations, and source changes. Users can customize the period of interest for differential analysis, making it easier to identify trends and patterns in their projects. By leveraging differential analysis, users can gain a better understanding of their project's quality and make data-driven decisions to improve it.
