- Rename plugin/evm/upgrade/subnetevm package to feewindow - Rename SubnetEVMTimestamp to EVMTimestamp (JSON: evmTimestamp) - Rename IsSubnetEVM method to IsEVM - Rename SubnetEVMDefaultChainConfig to EVMDefaultChainConfig - Rename TestSubnetEVMChainConfig to TestEVMChainConfig - Rename TestPreSubnetEVMChainConfig to TestPreEVMChainConfig - Rename ethclient/subnetevmclient to ethclient/evmclient - Update VM factory ID from "subnetevm" to "evm" - Remove all backward compatibility aliases - Update all documentation and comments Breaking change: This removes all SubnetEVM naming - only "EVM" is supported. No backward compatibility maintained as per user requirement.
