New LuxCoreRender v2.0beta1 release is available at:
https://luxcorerender.org/download
v2.0 release notes are available here:
https://wiki.luxcorerender.org/LuxCoreR ... Notes_v2.0
The complete list of changes between alpha7 and beta1 in Luxcore API is available here:
https://github.com/LuxCoreRender/LuxCor ... _v2.0beta1
The complete list of changes between alpha7 and beta1 in BlendLuxCore is available here:
https://github.com/LuxCoreRender/BlendL ... _v2.0beta1
This version includes new heterogeneous volume rendering code, a major performance improvement when rendering high resolution images with OpenCL, full light groups support in BlendLuxCore, the first complete version of network rendering support, many fixes and more.
P.S. after a couple of days of testing, if all goes well, this is going to be a the first public release of v2.0 and it will be announced on the old forums and web site. This will end the (not so close) alpha stage.

Note: there is a bug in PyInstaller on Linux affecting PyLuxCoreTools (i.e. network rendering). you can find the details here:
https://github.com/LuxCoreRender/LuxCore/issues/80
Short version: you can actually use network rendering only on Windows, not Linux.

Thanks for update
Found couple of issues:
1. Glass Rough doesn't work using OpenCL
2. small differences in final results (renderings) between both engines and even using same engine with different devices (IIRC, later one is known bug -
different results: CPU vs GPU/OCL (@ LuxRender forum).
e.g.
BiDir (also used as reference for comparison)
Path CPU
Path GPU
BiDir VS Path CPU (difference+gamma2)*
BiDir VS Path CPU (difference+gamma2)*
Path CPU VS Path GPU/OCL (difference+gamma2)*
-------------------------------------------------------------------------------------------------------
* Used GIMP. Layer Mode: Difference; Gamma upped to 2, to emphasize the difference

This bug was a pure concentrate of cut&paste errors:

The bug you linked has been fixed a while ago. As far as I can see, the PATHCPU and PATHOCL output is exactly the same (once #1 has been fixed).

You should use the .exr for comparison (and gamma 1.0 because it doesn't make sense to me to do a comparison in a non-linear space). Anyway, the output is supposed to be exactly the same only on the long run (i.e. in a noise free render).

TYVM for corrections & tips.
Taking notice... testing further...
