Short description of error
The scene was created with blender 2.8. After opening in Blender 2.81, the rendering is not same :
Blender 2.80
Blender 2.81
Indeed, Blender added new nodes in the material. It's strange, for this reason I preferred to report it.
Blender 2.80
Blender 2.81
Exact steps for others to reproduce the error
Open this blend file with Blender 2.8 and after in Blender 2.81:
cube_b280.blend

Thats due to the versioning code of
13d469e6f0.@fclem: for cycles, this is not so nice, but it seems this material has seen some tweaking in Eevee as well [otherwise the
Material->blend_methodwould not be set, right?]Dont have a quick idea to solve nicely...
CC @brecht here as well
Nodes changed after import in blender 2.81to Nodes changed after import in blender 2.81 (due to versioning code of blend mode refactor)One idea would be to check what render engine is set in the scene but then you run into issue where someone will have setup his material to have an EEVEE (workbench) preview but a Cycles render (active renderer).
Doing it one way or another will never satisfy all the cases so that's why we went for a simpler approach where we convert all outputs that are used by EEVEE.

How about adding an extra output node for eevee, to which the "corrected" node setup is connected;
and leaving the unchanged setup connected to the - now separate - cycles output node?

Will mark this as a known issue as it works as intended.
