LDraw with Blender 2.8

[Lasse Boijens]

Fairly certain that that just means that the creator of the add-on needs to update it to work with blender 2.8 (so check if no newer version exists maybe?). If you're familiar with add-ons you might be able to do it yourself, yet I lack the expertise for that. What you could use as a workaround is to import the files in an older version of blender when the add-on was still supported, export/save as a different file format and then open that new file in blender 2.8.
