The Chandrasekhar Limit

Release

v1.1.0-beta.4 -- The Chandrasekhar Limit -- is a minor release that focuses on expanded test coverage (again!), along with a couple of minor iterations on the Merge spec.

Warning: To facilitate the testing of the scaled validator churn limit while avoiding the use of a >300k validator set, minimal config has been altered to reduce the CHURN_LIMIT_QUOTIENT. To our knowledge, minimal is not currently used for any testnets so shouldn't cause much issue, but be careful to port the config update to your testing infrastructure.
