What are the differences between OpenGL ES 2.0 and OpenGL ES 3.0

Question

I want to know what is the differences between OpenGL ES 2.0 and OpenGL ES 3.0.

What is the main advantage of OpenGL ES 3.0?

Answer 1

I think it would be best to read section "Version 3.0 and Before -> New Features" on the official specs

And it is backward compatible with ES 2.0.
