HTML Working Group Updated HTML 5.1, Differences from HTML4, Canvas 2D Context Level 2, and Published Three Notes

The HTML Working Group has updated three Working Drafts and published three Group Notes:

• a Working Draft of HTML 5.1. This specification defines the 5th major version, first 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.
• a Working Draft of Differences from HTML4. HTML is the core language of the World Wide Web. The W3C publishes HTML5 and HTML5.1. The WHATWG publishes HTML, which is a rough superset of W3C HTML5.1. "Differences from HTML4" describes the differences of the HTML specifications from those of HTML4, and calls out cases where they differ from each other.
• a Working Draft of HTML Canvas 2D Context, Level 2. This specification defines the 2D Context for the HTML canvas element. The 2D Context provides objects, methods, and properties to draw and manipulate graphics on a canvas drawing surface.
• a Group Note of HTML5: Edition for Web Authors. This document, now discontinued and made available for historical purposes, is targeted toward Web authors and others who are not UA implementors and who want a view of the HTML specification that focuses more precisely on details relevant to using the HTML language to create Web documents and Web applications.
• a Group Note of main element - an HTML5 extension specification. This specification, now integrated into the HTML specification and no longer developed separately, defines an element to be used for the identification of the main content area of a document. It also defines an HTML element that embodies the semantics and function of the WAI-ARIA landmark role=main.
• a Group Note of HTML: The Markup Language (an HTML language reference). This document describes the HTML markup language and provides details to help producers of HTML content create documents that conform to the language. This document has been discontinued and is only made available for historical purposes. For an up to date reference on HTML elements (and more) please consult Web Platform Docs.
