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.

The Web Platform Working Group invites implementation of UI Events KeyboardEvent code and key Values:

• UI Events KeyboardEvent code Values: This document provides an overview of the various keyboard layouts and specifies the KeyboardEvent.code values that should be used for each of the keys. Unlike the key values described in UIEvents-key, the code values are based only on the key’s physical location on the keyboard and do not vary based on the user’s current locale. This specification was formerly titled DOM Level 3 KeyboardEvent code Values.
• UI Events KeyboardEvent key Values: This document specifies the set of valid key attribute values that must be used in the KeyboardEvent.key attribute to encode the key’s meaning. The key value for a particular key will differ based on the user’s current locale setting.
