Better insights and reliability for Real User Monitoring

Web Vitals now include page context: Performance spans for Core Web Vitals now capture page attributes like origin, route, hash, search parameters, and hostname. This makes it easier to identify which specific pages or routes are causing performance issues for your users.
Smarter view session tracking: The Browser SDK now starts a new view session when users return to your tab after switching away. This ensures you get accurate engagement metrics that reflect actual user attention patterns.
More reliable telemetry delivery: The SDK now uses XHR by default for sending telemetry data, only falling back to beacon mode during page unload. This improves delivery reliability and reduces unnecessary beacon usage.
Simplified SDK configuration: Removed the flushIntervalMs configuration option from the public API. The SDK now relies on browser-optimized default batching behavior, making configuration simpler while maintaining performance.

Browser SDK was creating unnecessary view rollovers when flushing telemetry data, which caused duplicate view spans and affected trace accuracy
