Introducing XRP Ledger (rippled) version 1.2.2

Ripple has released version 1.2.2 of rippled, our reference implementation of the core XRP Ledger server.

Version 1.2.2 corrects a technical flaw in the fee escalation engine which could cause some fee metrics to be calculated incorrectly. In some circumstances this can potentially cause the server to crash.

Action Required

If you operate a XRP Ledger server, then you should upgrade to version 1.2.2 immediately.

Impact of Not Upgrading

If you operate a rippled server, but do not upgrade to 1.2.2 as soon as possible, then your server may experience restarts or outages.

Additionally, the MultisignReserve, fixTakerDryOfferRemoval and fix1578 Amendments are expected to become enabled no earlier than Wednesday, 2019-03-20. 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.

The Ripple technical operations team plans to deploy version 1.2.2 to all XRP Ledger servers under its operational control, including private clusters, starting at 2:00 PM PST on Wednesday, 2019-03-06. 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.
