Hi Nikola,
Thanks for the new Build, great job!!
I do not know if it was already reported, but using sky with HDRI, IR does not work properly: rotating the sky, the HDRI position does not change in IR (the same thing in previous build).
It also appears to be incompatible with the Greyscalegorilla Hdrlink plugin: in this case, turning the sky, Corona crashes.
Sorry for my bad English
