XRP Ledger 3.2.1 is now available. This fixes the manifest flood observed on Friday, July 31. The XRPL continued closing ledgers normally throughout. A post-mortem will follow soon for the community. Nodes previously accepted, stored and re-broadcast an unlimited number of manifests from unknown validator keys. 3.2.1 adds four limits: 1) Size cap per manifest - any single manifest larger than expected is rejected. 2) Receive cap - incoming batches over the limit are discarded, instead of breaking the peer connection. 3) Send cap - the bulk manifest greeting sent to each new peer is now bounded. 4) Cache cap - once 100 unknown keys are held, new ones are refused. We also no longer persist manifests from unknown keys to disk, so a flood cannot survive a restart. Please update immediately by following these steps: 1) Update normally to XRPL 3.2.1 2) Wait 1–2 min, confirm xrpld is running, it does not need to be in status full or proposing. 3) Restart xrpld again - very important.
