Revision as of 07:20, 29 December 2012

There are features that have been requested, but for which we are lacking implementor interest. Without two or more vendors interested in implementing the feature, they are unlikely to get added to the specs.

<img srcset>: a mechanism to enable adaptive images

<video> currentTime and seek using rational numbers Jer Noble Would expose the video's timebase, too, assuming it's constant. See also next line.

Cross-origin workers Travis Leithead? Ojan Vafai
Deferring <img> loads until the image is needed
