New versions of the execution and consensus clients — Geth, Nethermind, Besu, Erigon, Reth, Lighthouse, Prysm, Teku, Nimbus and Lodestar — with what node operators must do.
Nimbus v26.9.1 is a high-urgency release for Sepolia due to its 6 October Glamsterdam fork activation, and medium-urgency for other networks, along with v26.9.0. It changes only the validator client from v26.9.0, ignoring stale PAYLOAD_DUE_BPS runtime config values (#9152) to allow mixed-beacon-node setups and address "incompatible time configuration parameters" warnings; otherwise it behaves identically to v26.9.0.
