+### Added
+
+- Added output `disaster_recovery_bucket_names` to provide a map from input bucket names to disaster recovery bucket names.
+
 ### Fixed
 
 - Fixed `bucket_obj_adm` and `bucket_obj_vwr` variables causing "Invalid for_each argument" error when used with `append_random_suffix = true`. The `for_each` key for IAM member resources now uses the static input bucket name instead of the dynamically generated name (with random suffix).
