The recent release of Sonar 1.6 introduces the ability to manage quality profiles, allowing users to define and apply multiple sets of coding rules to different projects. Prior to this update, all projects were analyzed with a single set of predefined rules, leading to unnecessary noise in the quality data. With Sonar 1.6, users can now create and use multiple quality profiles, each containing a set of activated coding rules, thresholds for critical metrics, and parametrization for each rule. This feature enables users to tailor their analysis to specific projects or types of projects, reducing unnecessary noise and improving the accuracy of the quality data. Users can manage quality profiles through the Sonar web interface, creating new profiles by copying existing ones or from scratch, associating profiles with projects, and using advanced parameters to analyze multiple profiles simultaneously.``<|fim_start|>
