Metastore-level ABAC policies are in Beta

Metastore level ABAC policies are in Beta in Unity Catalog. You can now attach an ABAC policy (row filter, column mask, GRANT, or DENY) at the metastore level, so a single policy applies across every catalog in the metastore, including catalogs created later. This gives governance teams one place to enforce organization wide data protection rules without replicating a policy for each catalog.
