We've made some pretty major modifications to our addon and the latest release, V0.4.1, is looking pretty sweet! It's more robust thanks to some important bug fixes and has slightly faster file transfer speeds.
We tested V0.4.1 with some geometry nodes scenes from blender's demo files and Blender 2.93 to make sure its got that covered.
The article linked I've linked to on our website explains the full details of what's new and has a link to our download page.
Spoiler, you do need a (free) account on our website to access the download section, and V0.4.1 is currently in early access, so if you want to grab it, you will need to be supporting our development fund with a monthly donation :), others have done this and we're slowly unlocking more and more recent builds of Crowdrender for free!
