Blender 2.81: Eevee
Transparency handling has been reworked and now supports the same BSDF combinations as Cycles (d5002f007e8d).
The Additive and Multiply blend mode have been replaced by shader equivalent that is compatible with Cycles. Compatibility code has been added to load blend file containing materials using these deprecated blend modes, but there is a corner case where it can fail. (13d469e6f0c5)
Holdout is now supported and works with both opaque and semi transparent surfaces. (67c10dbf1322)
