Yes. It was announced on the keynote that each profile would have its own bookmarks, history, cookies etc.
 
Unfortunately not. It seems both bookmarks and reading list are shared between all profiles.
 
I was hoping to have different websites in my favourites bar, depending on whether i had the personal or work focus on, but it doesn't seem like you can do that. It's the same favourites for everything.

It's a good idea, but the haven't completely followed through on it
 
I figured it out, or rather the Apple video shows how. the stock profiles it creates do not allow this. You have to create a new profile and then there is a checkbox for use existing bookmarks or create new ones.
 
Scratch that. They still sync. I started to delete book marks only to find that they synced between profiles.
 
After one recent update my separate profiles no longer share bookmarks…wish they did! What’s the point of keeping bookmarks if they’re not available?
 
Profiles have separate favorites but share bookmarks. If you want truly separated bookmarks, try using only tab group favorites.
