Lionel

v1.3.0-rc.5 -- Lionel -- is the fifth release candidate for the coming Capella upgrade.

This release sets the mainnet Capella fork epoch (CAPELLA_FORK_EPOCH) value.

Note that to be cautious, we still use the rc pre-release to avoid any last-minute updates. We will bump to v1.3.0 right after the mainnet fork is activated.
