An API to interact with the application cache, which is a set of cached resources.
You can do window.applicationCache to get the ApplicationCache object that applies to the active document of that window. More on application caches here.
DataTransfer API
The DataTransfer objects are used to expose the drag data store that underlies a drag-and-drop operation. More on drag and drop here.
A command is the abstraction behind menu items, buttons, and links. They are defined to have facets (label, hint, icon, etc.) and are exposed on elements using this API.
As of this writing, there is no proper definition to this. But we can assume it'll extend our client-side validation tool arsenal.
For example, you can go back (window.history.back()) and forward (window.history.forward()). More on session history here.
An API to interact with the <audio> and <video> elements.
You can do things like play (controller.play()) and pause (controller.pause()). More on media elements here.
Text Track API
An API to interact with the <audio> and <video> associated text tracks, like subtitles or captions.
You can get a media element and get a track from it like media.textTracks[0] (for the first one).
A textTrack element has it's own API which can return things like the language, readyState, mode, etc. More on media elements here.
APIs for the text field selections
The input and textarea text elements define an API for handling their selection.An API to interact with the <audio> and <video> associated text tracks, like subtitles or captions.
You can get a media element and get a track from it like media.textTracks[0] (for the first one).
A textTrack element has it's own API which can return things like the language, readyState, mode, etc. More on media elements here.
APIs for the text field selections
You can select everything in a text field with the select() function, or use selectionStart and selectionEnd to get the currently selected text.
Related specifications
Now I present to you:
- Specs that were originally in the HTML5 spec, but were later moved out into their own.
- Specs worked on by the Web Apps Working Group (in charge of HTML5).
- Other related/interesting specs.

Enhances the XMLHttpRequest object with new features, such as cross-origin requests, progress events, and the handling of byte streams for both sending and receiving.
And, again, these are not it. There are other working groups in the W3C besides the Web Apps one, each one with specifications they're working on. It's crazy, I know, but hopefully this will give you an idea of what's coming. I strongly recommend you to research more about it and experiment.
Thanks for reading and let me know your comments.
