Browser agent v971

August 17, 2016


The Browser Agent, sometimes called the JS Agent, has multiple variants: Lite, Pro, Pro+SPA. Unless noted otherwise, all features/improvements/bug fixes are available in all variants of the agent.

New features

  • Add support for keyboard change events [Pro+SPA]: Keyboard events will now automatically trigger a Browser Interaction timing.
  • Browser Timing Events now have Traced Callback Duration [Pro+SPA]: In order to match the attributes on other New Relic Browser related events, the Browser Timing events now include callback durations by default.


  • Change harvest to not use sendBeacon: We now use the sendBeacon native API only for page unload. The agent will now attempt to use an XHR when available and save sendBeacon for unload events, in order to reduce the data transferred using the sendBeacon API.

How to upgrade

To upgrade your agent to the latest version, see Upgrade Browser agent.
