Naveen,

From your list, the book does cover:
- canvas2d
- webgl (3d)
- motion
- geolocation
- web storage (both localstorage and websql/indexeddb)
- physics

It doesn't cover microdata as that doesn't strongly apply to game programming.

I'm not sure what you meant by

Dynamic Content Injection
Video Destruction

.

[Naveen Madarapu]

Dynamic Content Injection
i mean of this is without using any scripting languages can we inject our content based on client request in pages..
Video Destruction means
in a video when we are going to next frame previous frame is destroyed just like specified in video editing tools

In a general sense HTML5 is an upgrade to HTML4. Almost everything you know about HTML4 still applies to HTML5, you just have new set of tags to work with.

And a lot of new API.
