The new and changed settings below were not documented in the browser or announced on the official Brave blog. I did not notice them myself until I was setting up a new profile. However, they were documented and tracked in this detailed and illustrative issue on Brave’s GitHub repository.
New place for managing cookies (affects current recommendation!)
Old setting for sanitizing on close

New, less intuitive setting
Settings > Privacy and security > Sites and Shields Settings > Click on the 'Additional content settings' toggle > On-device site data > Delete data sites have saved to your device when you close all windows.

New script un/blocking features
The browser now has a new feature that allows you to see the specific scripts Brave has blocked if you toggled the Block scripts switch either globally or per-site. When browsing a site, they also offer the option to temporarily unblock specific scripts or allow them all.
