Compatibility with London Upgrade
As the report stated, in order to be compatible with the London hard fork, node operators need to upgrade their running client versions, such as go-ethereum (geth), Nethermind, Erigon (f.k.a. TurboGeth), Besu, OpenEthereum (f.k.a. Parity), EthereumJS VM. The versions support London on the Ethereum mainnet. The report provides a download link for each client.
The report noted:
“These releases are different from the previously announced releases that supported London on testnets. Previous vesions do not support London on mainnet.
“The OpenEthereum client will be deprecated after the London upgrade. The OE team is working with Erigon on a smooth transition path for users.”
Stressing the significance of London, the report points out that the upgrade will change how the target gas limit is handled on the network.
