⚠️ Mainnet-only upgrade for node operators. Do not upgrade your testnet nodes. This release fixes a validation bug on mainnet where transactions with gas limits above ~16.7M were incorrectly rejected, blocking large contract deployments. All node operators must upgrade to maintain network compatibility.
Nodes running older versions will reject blocks containing transactions with gas limits above 16.7M. Upgrading promptly avoids falling out of sync when validators raise the limit.
