Version 4 to Version 5 Migration Guide

This guide explains a breaking change in v5.0.0 and how to upgrade from v4.1.0 to v5.0.0.

With the XLS-0070-credentials amendment, the DepositPreAuth transaction can now preauthorize credentials, not just an account like before.

Because of this change, new DepositPreAuthObject ledger objects on the XRPL might have:

• No Authorize field
• A new field called AuthorizeCredentials

So in v5.0.0, the Authorize field is now optional.

When calling ledger_entry or account_objects in rippled (starting v5.0.0), the response for a DepositPreAuthObject will include either Authorize or AuthorizeCredentials, not both.

Before using the response, check if the Authorize field is present.
