World Chain Activates Karst Upgrade, Requiring New Node Software

  • —Karst upgrade went live on September 21 at 12:00 UTC
  • —Operators need op-geth v1.101701.0+ and op-node v1.16.9+
  • —Older node versions risk falling out of consensus
  • —No token migration or user action required
Why it matters: The upgrade is purely operational for L2 infrastructure: users see no change, but node operators must update to stay on the canonical chain.
