Administration

Single-page applications are now tracked automatically – page views are sent with each change of the browser history state. You can turn SPA tracking on or off in Administration > Sites & apps > Data collection > SPA > Track page views in a single-page application.

Our JavaScript tracker now uses the [navigator.sendBeacon()](https://developer.mozilla.org/en-US/docs/Web/API/Navigator/sendBeacon) method to send data from a client to a server. This method is more reliable than the previous one because it sends data asynchronously and doesn’t impact the loading of the next page.
Our JavaScript tracker now uses the [PerformanceNavigationTiming](https://developer.mozilla.org/en-US/docs/Web/API/PerformanceNavigationTiming) interface instead of the legacy [Performance.timing](https://developer.mozilla.org/en-US/docs/Web/API/Performance/timing) property to measure page performance metrics.

We fixed a bug blocking some data downloads in the site inspector for Chrome. Now you’ll see all collected data for heatmaps, clickmaps and scrollmaps.
