This is the first reader to fully support the third revision of the EPUB standard that adds many features such as Media overlay, JavaScript, SVG, MathML, and video.

Beyond EPUB3
People today expect more and more Multimedia in the Internet and in Digital books. The IDPF has responded to this with the EPUB3 standard published in 2011. However, although the new standard is a year old, most readers applications are are still EPUB2 compatible, some of them with some extensions to support the new capabilities of the new standard.

However EPUB3 although very advanced in it's features still does not contain 3D objects. The Gyan Reader's newest innovation is it's capability of presenting 3D images.
