V4.2.1

Welcome to Prysm Release v4.2.1! This release is highly recommended for stakers and node operators, possibly being the final update before V5.

⚠️ This release will cause failures on Goerli, Sepolia and Holeski testnets, when running on certain older CPUs without AVX support (eg Celeron) after the Deneb fork. This is not an issue for mainnet
