v0.6.1

Summary

Important

This release is required for GIWA Sepolia node operators to keep following L1 after the Ethereum Sepolia Glamsterdam hardfork, which activated on October 6th, 2026.
op-node versions before v1.19.5 cannot verify post-Glamsterdam L1 block headers (failed to verify block hash), so derivation halts and the safe/finalized heads stop advancing. Nodes running v0.6.0 should upgrade to this release.
See: https://github.com/ethereum-optimism/optimism/releases/tag/op-node%2Fv1.19.5

Key Details

• Ethereum Sepolia Glamsterdam
  • Upgraded op-node to v1.19.5, which supports the new L1 block header fields introduced by Glamsterdam
  • Added OP_NODE_P2P_GOSSIP_TIMESTAMP_THRESHOLD=3600s to .env.sepolia (operators with a customized .env.{network} should add it as well)
• Fixes
  • The JWT generator now regenerates the secret when the file exists but is empty
  • op-reth --max-outbound-peers is now configurable via RETH_MAXPEERS (default 100)
  • Installed ca-certificates in the reth runtime image so op-reth can connect to the HTTPS sequencer endpoint
• Node Versions
  • op-reth: v2.3.3
  • op-node: v1.19.5
