v3.2.8

Recommended Upgrade

• Security improvements
  • Rate limit ADDR P2P messages.
    • This prevents a potential DoS attack vector where malicious actors can cause resource exhaustion of the node host.
• Performance improvements
  • -walletfastselect flag can be used to speed up UTXO selection for large wallets
    • This only works for simple utxo unlock scripts.
    • Using this option will fail to select complex scripts unlock scripts like multi-sig.
    • This can be set as a global default in defid or passed to defi-cli to set per-request context.

Upgrade Notes

• For >= 3.2.4, no reindex needed. Drop-in upgrade.
• For >= 3.2.0 and <= 3.2.3, reindex is recommended, but optional and can be drop-in upgrade.
• For nodes >=3.0.x, one of the following is required:
  • Sync from any of snapshots from the DeFiChain team (below)
• For all other updates, one of the following is required: a fresh sync, the most recent snapshot.
• For nodes that are being restored from recent snapshot, as with all updates before: -rescan for the wallet txs and additionally -spv_resync for users who hold BTC. If either isn't used, they may not be shown in the wallet until rescanned/resynced.
