Navigation Timing 2 Draft Published

The Web Performance Working Group has published a Working Draft of Navigation Timing 2. This specification defines a unified interface to store and retrieve high resolution performance metric data related to the navigation of a document.

The Group also updated the Candidate Recommendation of Resource Timing, which defines an interface for web applications to access the complete timing information for resources in a document. The main change is that onresourcetimingbufferfull is now an event handler instead of a callback function. A diff document is available.
