The following amendments have been introduced since Clio 2.4.1 and have transaction model changes. Clio 2.5.0 is built with libxrpl 2.5.0, which supports these amendments.

If these amendments are enabled and you have not upgraded Clio to 2.5.0 or newer, the ETL will be amendment blocked and new ledgers will not be processed.
