Luminar Ai has been out since late 2020 now. Its April 2021 now. Go to Skylum's website and thoroughly check out the differences in Ai version and this version 4. There are big differences, some of which you will not like. Looks are now templates, be sure to import from v4 (3 won't work) as you install Ai. They will reside in the 'legacy' folder and you will not see a hierachy therein nor there icons, just a loooong list of yours and import presets. You also CANNOT import your library here. You will have to start from scratch again.....ugh. You however will most likely like the Ai introduced in this new version, its quite amazing. Sticking with LR myself for library purposes and Ai AND 4 for as plugins.
