This release incorporates a number of important features, bugfixes and functional improvements. Please refer to the Git commit history for more detailed information.

Release Overview

As part of Ripple Labs’ ongoing commitment toward improving the protocol, the rippled team is excited to announce autobridging — a feature that allows XRP to serve as a bridge currency. Autobridging enhances utility and has the potential to expose more of the network to liquidity and improve prices. For more information please refer to the autobridging blog post.

Toolchain support

The minimum supported version of GCC used to compile rippled is v4.8. Please follow these instructions if you have not upgraded already.

While it may be possible to compile rippled on (virtual) machines with 4GB of RAM, we recommend compiling on (virtual) machines with 8GB of RAM or more. If your build machine has more than one CPU (grep '^processor' /proc/cpuinfo | wc -l), you can use them to assist in the build process by compiling with the command scons -j[number of CPUs - 1].

The minimum supported version of Boost is v1.57.0. You must upgrade to this release or later to successfully compile this release of rippled. Please follow these instructions if you have not upgraded already.

Important rippled.cfg update

With rippled version 0.28, the rippled.cfg file must be changed according to these instructions:

  • Change any entries that say

admin = allow to admin =

  • For most installations, 127.0.0.1 will preserve current behavior. 0.0.0.0 may be specified to indicate "any IP" but cannot be combined with other IP addresses. Use of 0.0.0.0 may introduce severe security risks and is not recommended. See docs/rippled-example.cfg for more information.

More Strict Requirements on MemoType

The requirements on the contents of the MemoType field, if present, are more strict than the previous version. Transactions that can successfully be submitted to 0.27.4 and earlier may fail in 0.28.0. For details, please refer to updated memo documentation for details. Partners should check their implementation to make sure that their MemoType follows the new rules.

New Features

  • Autobridging implementation (RIPD-423). This feature will be turned on May 12, 2015.

  • 127.0.0.1 is no longer a default admin IP.
  • 0.0.0.0 may be specified to indicate "any IP" but cannot be combined with other MIP addresses. Use of 0.0.0.0 may introduce severe security risks and is not recommended.
