Visibility, Timing Control for Script-Based Animations, Navigation Timing

The Web Performance Working Group published three drafts
  • a First Public Working Draft of Page Visibility, which defines a means for site developers to programmatically determine the current visibility state of the page in order to develop power and CPU efficient web applications.
  • a First Public Working Draft of Timing control for script-based animations, which defines an API web page authors can use to write script-based animations where the user agent is in control of limiting the update rate of the animation. Using this API should result in more appropriate utilization of the CPU by the browser.
  • an update to the Candidate Recommendation for Navigation Timing, which defines an interface for web applications to access timing information related to navigation and elements.
