The Ethereum Pectra upgrade has been activated on the Sepolia testnet, the last major testing phase before the mainnet upgrade goes live, which is expected to be launched next month. The Pectra upgrade (a combination of the "Prague" execution layer and the "Electra" consensus layer update) introduces several improvements, including improved wallet user experience and account abstraction with EIP-7702, increased validator staking caps from 32 ETH to 2,048 ETH with EIP-7251, and increased scalability by increasing the maximum number of data blocks with EIP-7691.
