- change bl_info["support"] to COMMUNITY. because Blender do not support TESTINg anymore.
- now plugin should be installed in addons folder, not addons_contrib, due to blender changes.
- remove the reference about mesh.polypons.loop_total. because it is readonly now. (blender 3.6 changed)
- change uv assign method. use new properties instead. (MeshUVLoop is deprecated in blender 3.5 and removed in blender 4.0)
