The Glamsterdam upgrade has moved into the final stage of development and is being tested with all planned EIPs before the launch of public testnets. The exact activation date has not been set; the launch is expected in the second half of 2026.
Ethereum Foundation developer Paritosh Jayanti called Glamsterdam probably the largest fork of the network since The Merge in 2022: it includes ePBS (EIP-7732), Block-level Access Lists (EIP-7928) and a large-scale revision of operation costs.
