Mar 1, 2025March 2025: Delivered a security-focused access control improvement for Babylon's User Catalog by introducing a per-namespace RoleBinding (babylon-user-catalog-access) to grant catalog item access within each namespace. This fix aligns with cluster role-based RBAC to resolve an access issue and standardize permissions across projects. The change is tracked in commit 841abb6e343cb156f7685aea2aad129262074a29 and supports issue #2461. Overall, the update strengthens security, reliability, and maintainability of catalog access across the redhat-cop/babylon repository.
