Version 3.4.1 of xrpld, the reference server implementation of the XRP Ledger protocol, is now available. This emergency release for security-sensitive issues in the XRPL protocol was previously published as binary-only packages on 2026-09-26.
This release introduces a new amendment, fixBatchV1_2, with the default vote set to "Yes". The amendment also contains other fixes for security and stability.
Action Required
If you run an XRP Ledger server, upgrade to version 3.4.1 as soon as possible to ensure service continuity. The new fixBatchV1_2 amendment has already become enabled on Mainnet, so older releases are now amendment blocked.
