rippled Version 1.1.0

The rippled 1.1.0 release 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. The 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.

rippled Version 0.90.1

The rippled 0.90.1 release includes fixes for issues reported by external security researchers.

This release has no new features.

  • Verify serialized public keys more strictly before using them
    (RIPD-1617, RIPD-1619, RIPD-1621)

    encoding/decoding logic (RIPD-1618)
