The Device and Sensors Working Group has published a Proposed Edited Recommendation of Vibration API. This specification defines an API that provides access to the vibration mechanism of the hosting device. Vibration is a form of tactile feedback. Comments are welcome through 18 September.

The Web Platform Web Working Group has published a Working Draft of Indexed Database API 2.0. This document defines APIs for a database of records holding simple values and hierarchical objects. Each record consists of a key and some value. Moreover, the database maintains indexes over records it stores. An application developer directly uses an API to locate records either by their key or by using an index. A query language can be layered on this API. An indexed database can be implemented using a persistent B-tree data structure.

The Web Platform Working Group has published a Working Draft of HTML 5.2. This specification defines the 5th major version, second minor revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features continue to be introduced to help Web application authors, new elements continue to be introduced based on research into prevailing authoring practices, and special attention continues to be given to defining clear conformance criteria for user agents in an effort to improve interoperability.

The Geolocation Working Group invites implementation of the Candidate Recommendation of DeviceOrientation Event Specification. This specification defines several new DOM events that provide information about the physical orientation and motion of a hosting device.

The W3C Social Web Working Group is calling for implementations of Micropub, which is now a Candidate Recommendation. Micropub provides a mechanism for communication between independently developed clients and servers to allow creating, updating and deleting social content. For users, an immediate benefit is the possibility to change between or use multiple third-party posting clients with their own data storage. Before being brought to W3C for standardization, Micropub already had over a dozen independent implementations in the IndieWebCamp community.
