Ripple has released version 1.2.1 of rippled, our reference implementation of the core XRP Ledger server.

Version 1.2.1 introduces several fixes including:

A change in the information reported via the enhanced crawl functionality introduced in version 1.2.0.

A fix for a potential race condition when processing a status message for a peer.

A fix for a technical flaw that could cause a server to not properly detect that it had lost connectivity.

Version 1.2.1 also adds the delivered_amount field to more responses to simplify the handling of payment or check cashing transactions.

If you operate a XRP Ledger server, then you should upgrade to version 1.2.1 immediately.

Ripple expects the MultisignReserve, fixTakerDryOfferRemoval and fix1578 Amendments to become enabled no earlier than Tuesday, 2019-03-12. When this happens, if you are not running release 1.2.0 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 MultisignReserve, fixTakerDryOfferRemoval and fix1578 Amendments do not become enabled, then your XRP Ledger server will not become Amendment blocked and should continue to operate.

The first log entry should be the change setting the version:

The Ripple technical operations team plans to deploy version 1.2.1 to all XRP Ledger servers under its operational control, including private clusters, starting at 2:00 PM PST on Tuesday, 2019-02-26. At that time, Ripple plans to start voting in favor of the fix1578 Amendment. The deployment is expected to complete within 4 hours. The network should continue to operate during deployment and no outage is expected.
