The Ethereum Foundation said that after a scope assessment of the Pectra fork, a successful interoperability event, and four development networks, the first short-term Pectra testnet Mekong is now launched. The Mekong testnet contains all EIP proposals that will be used for the Ethereum Pectra fork. These changes include user experience (UX) improvements implemented through EIP-7702, pledge changes implemented through EIP-7251, deposit and withdrawal mechanism changes implemented through EIP-6110/EIP-7002, etc.
