## Errors of failed v4 batch items

You can now see why an item of a v4 batch failed. A failed item has an `error` object with a `code` and a `message`. The `message` explains the failure and the action to take. Before, a failed item did not show a reason.

## Batch items at the processing rate limit

When your account reaches its processing rate limit, Zep now waits and then processes the batch item again. The wait does not use one of the processing attempts of the item. If the rate limit continues for a long time, the item fails. A failed item of a v4 batch then has the `rate_limited` error code. Before, each rate-limited attempt counted toward the attempt limit, and an item failed after fewer waits.
