The World Wide Web Consortium (W3C) has plans to release HTML5.1 in September 2016. The work is being conducted by the W3C Web Platform Working Group. The long term goal is to release a stable version of HTML as a W3C Recommendation once per year.
Among the core goals stated by W3C for future HTML specifications was to match reality better, to make the specification as clear as possible to readers, and to make it possible for all stakeholders to propose improvements, and understand what makes changes to HTML successful.
To ship the HTML5.1 Recommendation in September 2016, the group plans to have a Candidate Recommendation by the middle of June, following a Call For Consensus based on the most recent Working Draft. To make it easier for people to review changes, an updated Working Draft will be published approximately once a month with changes noted within the specification itself.
The specification is on
Github and anyone who can make a Pull Request can propose changes. The group suggest individuals that find something in the specification that generally doesn’t work in shipping browsers to file an issue or file a Pull Request to fix it. The group will generally remove things that don’t have adequate support in at least two shipping browser engines.
