v3.2.2-rc.0

We are excited to announce a Sepolia Only Testnet release, v3.2.2-rc.0 🎉

This is a Sepolia Only Testnet release. Please only upgrade your Sepolia beacon node and validator to this release before tomorrow's Shanghai Capella hard fork time 2/28/2023, 4:04:48 AM UTC. Please DO NOT use this release on Mainnet or any other testnets. Summary:

• This is a mandatory release for Sepolia testnet
• This is not recommended for everything else, including Mainnet and Goerli
