EGL 1.3 versus 1.4

Hi all!

I wonder if any document describing differences between EGL 1.3 and 1.4 exists.
Currently I browse specification of EGL 1.4 with changes … 130211.pdf
but I am not sure whether these “changes” are regarding 1.3 or some earier versions of spec but still for 1.4 … :?

Could you clarify this topic a little bit?
