Ripple has released version 1.4.0 of rippled, the reference implementation of the core XRP Ledger protocol. To learn more about how to build and run a rippled server, see Manage the rippled Server.

Action Required

If you operate an XRP Ledger server, then you should upgrade to XRP Ledger version 1.4.0 by Friday, 2020-01-17, to ensure service continuity.

Impact of Not Upgrading

Ripple expects the fixPayChanRecipientOwnerDir and fixCheckThreading Amendments to become enabled on Friday, 2020-01-17. When this happens, if you are not running release 1.4.0 or greater, your server will become amendment blocked, meaning that it:

• Cannot determine the validity of a ledger;
• Cannot submit or process transactions;
• Cannot participate in the consensus process;
• Cannot vote on future amendments; and
• Could rely on potentially invalid data.

If the Amendments do not become enabled, then your XRP Ledger server will not become Amendment blocked and should continue to operate.
