Did 1.8 change how artist aliases are handled and displayed?

I’m trying to understand what changed since the 1.8 update. I used to see all aliases of HKE aka David Russo (founder of the Dream Catalogue label) in the Bio section…and there are a lot (discogs lists them all) E.g. in the previous version, a distinction was made between HKE and Hong Kong Express…no more in 1.8…I had to create the latter as Primary Artist. They are both aliases of David Russo but are distinct entities.
