Introducing XRP Ledger (rippled) version 1.1.0

Ripple is pleased to announce the release of XRP Ledger (rippled) version 1.1.0.

The XRP Ledger version 1.1.0 release includes the DepositPreAuth Amendment, which, combined with the previously released DepositAuth Amendment, allows users to pre-authorize incoming transactions to accounts, by whitelisting sender addresses. XRP Ledger version 1.1.0 release also includes incremental improvements to several previously released features (fix1515 Amendment), deprecates support for the sign and sign_for commands from the rippled API and improves invariant checking for enhanced security.

Ripple recommends that all server operators upgrade to XRP Ledger version 1.1.0 by Thursday, 2018-09-27, to ensure service continuity.

Action Required

If you operate a XRP Ledger server, you should upgrade to XRP Ledger version 1.1.0 by Thursday, 2018-09-27, to ensure service continuity.

Impact of Not Upgrading

Ripple expects the DepositPreAuth or fix1515 amendments to become enabled on or after Thursday, 2018-09-27. When this happens, if you are not running release 1.1.0 or greater, your server will become amendment blocked, meaning that it:

  • Cannot determine the validity of a ledger;

  • Cannot be able to submit or process transactions;

  • Cannot participate in the consensus process;

  • Cannot vote on future amendments; and

  • Could rely on potentially invalid data.

If the DepositPreAuth and fix1515 Amendments do not become enabled, then your XRP Ledger server will not become Amendment blocked and should continue to operate.

  • The SHA-256 for the RPM is: ec50f3cec7dcbea8aaa2eb9d97c3c1fc02d44ce62203557b4cd213cf1b0fe4b5

  • The SHA-256 for the source RPM is: 936844990e70615183681c41884ea96804ee4130d6f9ec32242fb3a16120824f

For other platforms, please compile version 1.1.0 from source. See rippled build instructions by platform, or Build and Run rippled on Ubuntu Linux for further instructions.
