We are releasing v4.0.0 for the upcoming Capella/Shanghai ("Shapella") upgrade!

This release is mandatory for all mainnet Prsym beacon nodes and validators. The release enables Capella upgrade, scheduled on April 12, 2023, 10:27:35pm UTC and epoch 194048. Failure to upgrade will result in your node forking off the chain and the validator losing rewards and getting penalized for being offline.

To recap, you must upgrade your mainnet beacon node and validator client to v4.0.0 before April 12, 2023, 10:27:35pm UTC.

Please have a look below for the changes and detailed change lists.
