Ethereum's core developers have tentatively scheduled the Fusaka mainnet activation for December 3, following a successful testnet upgrade with no unresolved bugs. Additionally, BPO 1 & 2 upgrades are planned for December 17 and January 7, 2026. During the 167th Ethereum Consensus Layer Core Developers Meeting, it was also decided to maintain the current ePBS design for Glamsterdam, despite suggestions to split it into two EIPs, as such a change could delay the upgrade.
