+## Bug Fix
+- Fixes null conversion amounts for top-level subsidiaries missing a self-conversion exchange rate; rate now defaults to 1. Updates `converted_amount` values in `netsuite2__transaction_details`, `netsuite2__income_statement`, and `netsuite2__balance_sheet`.
+
+> **Note**: A `--full-refresh` is recommended after upgrading.
