+| New error handling option for `CALL { ... } IN TRANSACTIONS`: `ON ERROR RETRY`.
+This option applies an exponential delay between retries for transaction batches failing due to transient errors, with an optional maximum retry duration, and handles failure based on a specified fallback error mode if the transaction does not succeed within the given time.
+For more information, see xref:subqueries/subqueries-in-transactions#on-error-retry[`CALL` subqueries in transactions -> `ON ERROR RETRY`].
