rippled (XRP Ledger server) Version 2.0.0-rc7 (release candidate)

This is a release candidate. There are no code changes in rc7 vs. rc6; rather, we have only added a flag to override a superfluous error during the build process (which blocks packaging).

• General availability for api_version: 2. In order for requests to experience breaking changes, you must specify "api_version": 2. Thus, rippled 2.0 is backward-compatible for most users.
  • The "DeliverMax" field reflects the maximum amount that the payment may deliver. To get the amount of a payment, use the "delivered_amount" field.
  • 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".
  • The "ledger_index" is now always returned as an integer (not a string).
• Notable performance improvements in TPS (transactions per second) throughput.
• XLS-38 sidechains support, adding 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 improved since the previous major version.
