The Tracking Protection Working Group has published two documents today.

• A Working Draft Tracking Preference Expression (DNT). This specification defines the DNT request header field as an HTTP mechanism for expressing the user’s preference regarding tracking, an HTML DOM property to make that expression readable by scripts, and APIs that allow scripts to register site-specific exceptions granted by the user. It also defines mechanisms for sites to communicate whether and how they honor a received preference through use of the Tk response header field and well-known resources that provide a machine-readable tracking status.
• A Working Draft of Tracking Compliance and Scope. This specification defines the meaning of a Do Not Track (DNT) preference and sets out practices for websites to comply with this preference.

The Internationalization Working Group has published a Working Draft of Encoding. While encodings have been defined to some extent, implementations have not always implemented them in the same way, have not always used the same labels, and often differ in dealing with undefined and former proprietary areas of encodings. This specification attempts to fill those gaps so that new implementations do not have to reverse engineer encoding implementations of the market leaders and existing implementations can converge.

The WebFonts Working Group has published a Working Draft of WOFF 2.0 Evaluation Report. Web Open Font Format (WOFF) 2.0 is a proposed update to the existing WOFF 1.0 with improved compression. This report lists requirements for successful deployment, evaluates how the requirement may be met, and examines the compression gains and tradeoffs vs. code complexity, encode and decode time. This document is non-normative. Learn more about the Fonts Activity.

The CSS Working Group has published an updated Working Draft of CSS Grid Layout Module Level 1. This CSS module defines a two-dimensional grid-based layout system, optimized for user interface design. In the grid layout model, the children of a grid container can be positioned into arbitrary slots in a flexible or fixed predefined layout grid. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Learn more about the Style Activity.

The CSS Working Group published an updated Working Draft of CSS Fragmentation Module Level 3. This module describes the fragmentation model that partitions a flow into pages, columns, or regions. It builds on the Page model module and introduces and defines the fragmentation model. It adds functionality for pagination, breaking variable fragment size and orientation, widows and orphans.
