Hi James,
of course I have downloaded the new version on the day when you have put it online - and I've freezed my Blender 2.80 installations to the version of the same date. :)
The installation of Crows Render works well now. And using Crowdrender works well too as long as I'm using only Macs as nodes. When I add a Windows PC to the nodes all computers render too, but I only get a transparent / empty image as render result when they are finished. The Computer I'm working on is a Mac, 4 other Macs and 2 Windows 10 PCs are nodes. For me this is not a huge problem because my Macs (which are Hackintoshs) are faster than my other PCs).
But I'm still testing. I have found other bugs (with manual load balancing). I'll create a new post when my tests are finished. :)
