Ethereum developers deployed an emergency software update to the Prysm validator client ahead of the Glamsterdam upgrade test on the Sepolia testnet. Version 7.2.1 resolves a configuration issue that would have caused validators running outdated settings to produce low-capacity blocks, ensuring full participation in the upcoming network stress test. The Glamsterdam test will raise Sepolia’s gas limit from approximately 60 million to 200 million to validate Ethereum's future processing capacity improvements. This threefold increase simulates higher throughput for transactions and complex on-chain operations while testing node performance under elevated computational pressure. Sepolia serves as the primary testing ground for the next major Ethereum mainnet upgrade.
