The Global Illumination has been through many changes since it started.
Right now local real time probes are required 
in order to properly update lighting changes.

The probes contain a low resolution camera
that creates cube maps of its surroundings in real time
which is then used for GI. 

Because the lighting is image based,
bounces are practically infinite, 
which creates very convincing lighting all in real time.

This is all the info I can give on the GI at this time,
it is still in development and 
we cannot guarantee it will make the first beta release of this package.
