XRPLF/rippled 2.0.0-rc4

rippled (XRP Ledger server) Version 2.0.0-rc4 (release candidate)

on GitHub

This is a release candidate.

• Includes api_version 2 general availability.
  • The "DeliverMax" field reflects the maximum amount that the payment may deliver. To get the amount of a payment, use the "delivered_amount" field. "DeliverMax" is now provided for all Payment transactions, and successful transactions include "delivered_amount".
  • In api_version: 2, the "Amount" field is removed. In most cases, the field you actually want is "delivered_amount". But if you really want the field formerly known as "Amount", then you can use "DeliverMax".
  • In api_version: 2, "ledger_index" is always returned as an integer (not a string).
• Notable performance improvements in TPS (transactions per second): up to 4,300 TPS.
• XLS-38 sidechains support.
  • This is a large change and adds significant new functionality to the protocol.
• XLS-40 decentralized identity (DID) support.
• New server_definitions method.
• Many aspects of the code have been refactored and changed since the previous major version.
