Introducing XRP Ledger version 1.4.0

XRP Ledger (rippled server) version 1.4.0 has been released. The XRP Ledger version 1.4.0 introduces several new features and overall improvements to the codebase, including the DeletableAccounts Amendment, which allows users to delete XRP Ledger accounts and recover some of their account base reserve in the process.

The 1.4.0 release also includes improved peer slot management, improved CI integration and package building and support for C++17 and Boost 1.71.

Finally, the 1.4.0 release removes the code for the SHAMapV2 Amendment, which failed to gain majority support and has been made obsolete by other improvements.

Action Required

If you operate an XRP Ledger server, then you should upgrade to XRP Ledger version 1.4.0 by Monday, 2019-12-16, to ensure service continuity.

Impact of Not Upgrading

Ripple expects the DeletableAccounts Amendment to become enabled no earlier than Monday, 2019-12-16. When this happens, if you are not running release 1.4.0 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 DeletableAccounts Amendment does not become enabled, then your XRP Ledger server will not become Amendment blocked and should continue to operate.

Upgrading

Network Update

The Ripple technical operations team plans to deploy version 1.4.0 to all XRP Ledger servers under its operational control, including private clusters, starting on Monday, 2019-12-02. At that time, Ripple plans to start voting in favor of the DeletableAccounts amendment. The deployment is expected to complete within 4 hours. The network should continue to operate during deployment and no outage is expected.

Bug Bounties and Responsible Disclosures

As always, Ripple welcomes reviews of the XRP Ledger open source codebase and urges reviewers to responsibly disclose any issues that they may find. For more on Ripple's Bug Bounty program, please visit https://ripple.com/bug-bounty/.

Compilation Requirements & Compatibility

Starting with version 1.4.0, compiling the codebase from source on any platform requires a compiler that supports the C++17 ISO standard and version 1.70.0 of the Boost C++ libraries.

1.4.0 Change Log

New and Updated Features

  • The DeletableAccounts amendment which, if enabled, allow users to delete their XRP Ledger accounts and recover some of their base reserve.

  • Support for improved management of peer slots and the ability to add and remove reserved connections without requiring a restart of the server.

  • Preliminary support for post-processing historical shards after downloading to index their contents.

  • Reporting the master public key alongside the ephemeral public key in the validation stream subscriptions.

Bug Fixes

  • The fixPayChanRecipientOwnerDir Amendment which corrects a minor technical flaw that would cause a payment channel to not appear in the recipient's owner directory, which made it unnecessarily difficult for users to enumerate all their payment channels.

  • Respect the ssl_verify configuration option in the SSLHTTPDownloader and HTTPClient classes.
