The Second Screen Working Group has published a revised Candidate Recommendation of the Presentation API. That specification defines an API to enable Web content to access presentation displays and use them for presenting Web content.
Since publication as Candidate Recommendation in July 2016, the Working Group updated algorithms in the specification to fix issues identified through testing and implementation feedback. The actual interfaces did not change. The API was also restricted to secure contexts. A complete list of changes is available.
