The Internationalization Working Group invites implementation of the Candidate Recommendation of Encoding. The UTF-8 encoding is the most appropriate encoding for interchange of Unicode, the universal coded character set. Therefore for new protocols and formats, as well as existing formats deployed in new contexts, this specification requires (and defines) the UTF-8 encoding.

The Social Web Working Group has published a Proposed Recommendation for three documents:

• Micropub: The Micropub protocol is used to create, update and delete posts on one’s own domain using third-party clients. Web apps and native apps (e.g., iPhone, Android) can use Micropub to post and edit articles, short notes, comments, likes, photos, events or other kinds of posts on your own website.
• Activity Streams 2.0: This specification details a model for representing potential and completed activities using the JSON format.
• Activity Vocabulary: The Activity Streams 2.0 Core Syntax defines the JSON syntax for Activity Streams and a set of abstract types and properties that describe past, present and future Activities. This document defines the vocabulary properties.

Comments are welcome through 15 May 2017.

The Web Performance Working Group invites implementation of the Candidate Recommendation of Beacon. This specification defines an interface that web developers can use to schedule asynchronous and non-blocking delivery of data that minimizes resource contention with other time-critical operations, while ensuring that such requests are still processed and delivered to destination.
