Sentry Performance now supports INP (Interaction to Next Paint) as a new core web vital, allowing developers to monitor the performance of every interaction on a page and quickly identify issues that affect user responsiveness. This feature provides a more accurate measure of overall page responsiveness than First Input Delay (FID). Sentry also improved its tracing experience, offering a unified view of multi-service applications and making it easier to track user-facing issues back to backend services. Additionally, Sentry introduced a new workflow for mobile developers to detect and track the root cause of cold and warm starts in their apps, providing detailed insights into performance bottlenecks down to the line of code.
