XRPLF/rippled 2.0.0-rc3

rippled (XRP Ledger server) Version 2.0.0-rc3 (release candidate)

on GitHub

This is a release candidate.

• Includes api_version 2 general availability.
  • The "DeliverMax" field name clarifies that the field is the maximum amount that the payment may deliver. To get the amount of a payment, use the "delivered_amount" field. "DeliverMax" is provided for all Payment transactions regardless of api_version.
  • In api_version: 2, the "Amount" field is removed. In most cases, the field you want is "delivered_amount". But if you really, really want the field formerly known as "Amount", then look for "DeliverMax".
• 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
• Lastly, many aspects of the code have been refactored and changed since the previous major version.
