  • Single Page App navigations can be configured tell Boomerang to hold the SPA beacon until the page has completed other non-network activity
  • XHR instrumentation can be configured to send XHR beacons for every XHR, instead of combining them during SPA navigations
  • Custom Metric JavaScript variables can be configured to only be captured on specific URLs
  • XHR instrumentation has a new optional snippet that helps instrument XHR before boomerang.js has been loaded
  • Single Page App navigations now include NavigationTiming and/or ResourceTiming metrics for hard and soft navigations
  • Angular ui-router support
