The Flow Amendment is Now Available

The Flow Amendment became available on the Ripple Consensus Ledger in ledger 24,970,753 (2016-10-21T19:47:22Z).

This amendment replaces the payment processing engine with a more robust and efficient rewrite called the Flow engine. The new payments engine adds no new features, but improves efficiency and robustness in payment handling.

Action Required

If you operate a rippled server, then you should upgrade to version 0.33.0 or later, immediately, for service continuity.

Impact of Not Upgrading

If you operate a rippled server but don’t upgrade to version 0.33.0 or later, immediately, then your server will become amendment blocked, meaning that your server:

  • Cannot determine the validity of a ledger
  • Cannot submit or process transactions
  • Does not participate in the consensus process
  • Does not vote on future amendments

For instructions on updating rippled on supported platforms, see Updating rippled on supported platforms.

For other platforms, please compile version 0.33.0 from source.
