Suspect Commits is a feature that helps developers quickly triage issues by identifying who made the last change to the code that caused the error, and automatically assigning the issue to them. With this feature enabled, Sentry can provide more context to developers, such as stack trace links to their source code, making it easier for them to understand and fix the issue. The integration with Git Blame API allows Sentry to identify who changed specific lines of code and associated pull requests, increasing commit accuracy and reducing the time spent on triaging issues.
