Short description of error
Particle info node not working - This may not be a bug but something that has not been implemented yet.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Add an icosphere. Add a particle system to the default cube and in the Render settings set 'Render As' to object and select the icosphere. Then add a material to the icosphere. Open the Shader Editor and add a 'Math' node and a 'Particle Info' node to the material. Connect 'Age', from the Particle Info node to the first 'Value' input of the Math node and 'Lifetime' to the second. Set the Math node to Divide and connect 'Value' to the 'Base Color' node of the 'Principled Shader'. Switch to 'Look Dev' in the 3D view and play the animation, scaling the icosphere to see the particles clearly. All the particles are black, they should change from black to white as they fall. This is what happens in 2.79.

The attached file is a Blender 2.79 file

. It runs correctly in 2.79, but opening and running it in 2.8 (from the 12 June 19) the particles do not change color.
