Except Luminar 4 is losing it's support for Luminar AI. Still a bargain for £20.00 if you'll make use of it but it's not a Lightroom or photoshop replacement.
Edit: for the record, Luminar 4 runs fine on my PC.
No its not??? They are two distinct and totally different products and luminar 4 will still get free updates for at least another year until luminar 5 comes out
