Secrets in Unity Catalog is GA

Secrets in Unity Catalog is now generally available. You can store, govern, and access secrets as securable objects in Unity Catalog.

MANAGE no longer requires USE CATALOG or USE SCHEMA on the same object

The MANAGE privilege no longer requires a usage privilege ( USE CATALOG or USE SCHEMA ) on the object where MANAGE is granted. This change makes MANAGE behave more consistently with object ownership. Previously, MANAGE on a catalog or schema took effect only if you also held the appropriate usage privileges on that object.
