BlenderKit addon will be here since now:
https://github.com/BlenderKit/blenderkit
And all release notes , docs and information will be on BlenderKit website:
www.blenderkit.com
The move happens since Blender Foundation ended the commercial addon offering for all commercial addons.
This means a bit less comfort for our users, but also many new possibilities!
BlenderKit add-on is the official addon of the BlenderKit service for Blender 3d. (www.blenderkit.com)
It enables users to upload, search, download, and rate different assets for blender.
It works together with BlenderKit server.
