Introducing XRP Ledger (rippled) version 1.2.3

Ripple has released version 1.2.3 of rippled, the reference implementation of the core XRP Ledger protocol.

Version 1.2.3 corrects a technical flaw that could, in rare circumstances, cause the server to dereference a null pointer, which could result in the server process being terminated by the operating system.

Action Required

If you operate an XRP Ledger server, then you should upgrade to version 1.2.3 immediately.

Impact of Not Upgrading

If you operate a rippled server, but do not upgrade to 1.2.3 immediately, then your server may experience restarts or outages.

Additionally, if you are not already running release 1.2.0 or greater, then your server is 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.

For other platforms, please compile version 1.2.3 from source.

Set version to 1.2.3

Network Update

The Ripple technical operations team plans to deploy version 1.2.3 to all XRP Ledger servers under its operational control, including private clusters, starting at 2:00 PM PST on Tuesday, 2019-04-02. At that time, Ripple plans to also start voting in favor of the MultisignReserve Amendment. The deployment is expected to complete within 4 hours. The network should continue to operate during deployment and no outage is expected.

Known Issues

Version 1.2.3 has a bug that can cause the server to stop checking for updates to its configured validator list sites. If this happens, your server may lose sync with the network when its current validator list file expires. You can restore sync by restarting the rippled service. (This issue is related to the issues fixed in the version 1.1.1 release.) A fix for this issue is forthcoming.
