Happy new year everyone! We made great progress in standardizing the platform in 2011 and plan to continue doing just that with your help. You can join our mailing list to discuss issues with web development or join IRC if you prefer more lively interaction.
I will be taking the remainder of the month off and as nobody has volunteered thus far, WHATWG Weekly is unlikely to be updated in January. All the more reason to follow email and IRC.
Since last time the toBlob() method of the canvas element has been updated in revisions 6879 and 6880 to make sure it honors the same-origin policy (for exposure of image data) and handles the empty grid.
In the land of ECMAScript a proposal was made to avoid versioning by David Herman, which if successful will keep ECMAScript simple and more in line with other languages used on the web.

You might have missed this. Because of this lengthy thread on throwing for atob() space characters will no longer cause the method to throw from revision>6874 onwards. This is the WHATWG Weekly, with some standards related updates just before the world slacks off to feast and watch reindeer on Google Earth.
Shadow DOM
Dimitri Glazkov (from good morning, WHATWG!) published Shadow DOM. A while earlier he also published, together with Dominic Cooney, Web Components Explained. The general idea is to be able to change the behavior and style of elements without changing their intrinsic semantics. A very basic example would be adding a bunch of children to a certain element to have more styling hooks (since this is the shadow DOM the children will not appear as actual children in the normal DOM, but can be styled).
Encoding Standard
Two weeklies ago you were informed about the encoding problem we have on the platform. While HTML already took quite a few steps to tighten up things (discouraging support for UTF-7, UTF-32, etc. defining encoding label matching more accurately), more were needed. Especially when it comes to actually decoding and encoding with legacy encodings. The Encoding Standard aims to tackle these issues and your input is much appreciated. Especially with regards to the implementation details of multi-octet encodings.

James Hawkins proposed the intent element in a way that brings back memories of HTML4. Happy to be reminded we are over SGML now. This is the WHATWG Weekly.
Better autocomplete
Overnight a complete proposal for better autocomplete appeared on the WHATWG Wiki, apparently already experimentally implemented in Chrome (prefixed). It proposes a new autocompletetype attribute that takes values such as birthday and cc-number. The advantage over ECML is that changes only need to happen on the frontend. The backend can stay the same.
File API
Adrian Bateman proposed to remove the readAsBinaryString() method from the File API standard. Everyone else seems to be on board so it will likely go away soon. Thanks to ArrayBuffer the method became useless.
He also proposed a new argument for createObjectURL() to indicate the resource will only be used once and can then be garbage collected.
Stream API
Sort of analogous to Blob objects a new Stream object has been proposed by Microsoft and it comes with a bunch of friends too so you can interact with it. Combined with XMLHttpRequest this will allow streaming data to the server or downloading large amounts of data and processing it as it comes in.

If you want to contribute to the WHATWG Blog or Wiki, join IRC (#whatwg on Freenode). We had to shut down user registration unfortunately due to excessive spam. Welcome to another WHATWG Weekly. If it were themed, this would be about Sinterklaas.
Encoding problem
In response to Faruk Ate?' plea for defaulting to UTF-8, David Baron explained the platform encoding problem. The problem is that currently the default encoding varies per user (depending on locale primarily) and sites rely on locale-specific default encodings. Such sites visited by a user using a Dutch computer and a user using a Chinese computer, will render differently. In particular, their byte streams will be decoded using a different encoding. The implication is that the web is less global than it should be. How exactly we are to overcome the platform encoding problem, without everyone explicitly opting in to an encoding using <meta charset=utf-8> (please do so if you are a web developer), is still unclear. Ideas welcome!
WebVTT
Revision 6837 made it possible for WebVTT to be published as a standalone Living Standard. It will primarily be developed by the Web Media Text Tracks Community Group on the [email protected] mailing list. WebVTT is the platform's captioning and subtitle format (for HTML video) and its development can be tracked on Twitter via @webvtt.
Video conferencing
The same revision that let WebVTT be published as standalone document, removed everything related to peer-to-peer connections and video conferencing. The W3C Web Real-Time Communications Working Group forked our work in WebRTC 1.0: Real-time Communication Between Browsers and we (the WHATWG) are okay with them working on it instead.
Miscellaneous
My colleague Karl has been blogging again on the W3C Blog, read his summaries from the weeks of November 14 and
November 21.
Yours truly added native JSON support to XMLHttpRequest. Just set responseType to "json" and response will give you a JSON-decoded object once fetching is done.

Next to @WHATWG, we now have +WHATWG. Hopefully ?WHATWG is next. Not to dispair, WHATWG Weekly will remain right here, without funny characters preceding it.
HTML is big, so follow what interests you!
Ian Hickson announced a new system on the mailing list that allows people to subscribe to specific sub-topics in the HTML specification, such as <canvas> or the HTML Syntax and Parsing sections. You can do so right from the specification itself. If you are interested in topics that are not yet a sub-topic, please let us know.
XMLHttpRequest
XMLHttpRequest is now developed as a single specification again, to reduce confusion, and make it easier for everyone to look at the same copy. Some subtle changes have been made as well, such as allowing responseType to be set before invoking open(), and restrictions on synchronous usage outside a worker context are planned. Synchronous in the main thread is bad, and you will not find any new XMLHttpRequest goodness there real soon now.
Emails
Because not everyone writes sites in a way that prevents future specifications from breaking them, Cameron McCormack has thought up a proposal that should help to make API design less restrictive. Karl Dubost pointed out that using GET when you mean POST is a bad idea.
Ryosuke Niwa is still working on the UndoManager and DOM Transaction specification and posted about a re-introduced AutomaticDOMTransaction interface. He also announced an updated draft and summarized the changes thus far.
