This upcoming release will include light simulation as well as some other visual improvements.

These are a list of features that are included in the beta 1 update:

• 2D Ray tracing with global illumination

• New "Lighting" tab

• Modified internal rendering to use 16 bits per channel. This greatly improves color visuals with dark colors or large particles

• Added new "Max Dynamic Size" slider

• Added new "Min Dynamic Size" slider

• Now fullscreen is actually windowed borderless

You can find the current placeholder controls in the new "Lighting" tab
