Major changes in this release include:

• increase proposal performance with new validator REST APIs
• add proposal value and blinded status to trace
• add beaconblockproposer.builder-boost-factor
• add reduced memory mode for memory-constrained systems
• reduce memory usage when obtaining Dirk accounts
• reduce memory usage when generating beacon committee subscriptions
• add "controller.fast-track" flag
• update internal active validators count when Dirk not available at start
• warn when graffiti is not as expected, rather than refuse to use the proposal
• provide fallback location for dynamic graffiti
• relax proposal checks to enable DVT proposals
• add individual "controller.fast-track" flags for attestations and sync committees
• add 'failed' dimension for root to slot lookup metrics
• add 'deadline' builder bid strategy
• add builder configurations to allow more control over selection of bids
• add sync committee verification metrics to highlight when we were and were not included in a SyncAggregate
• add config setting to enable the above metrics
• alter logic for determining sync committee eligible accounts
• enable first strategies to be defined for beaconblockheader and signedbeaconblock
• tidy up log entries for sync committee summaries
• reduce unnecessary log entries from some strategies
• change builder bid factor to be a percentage rather than a multiplier
• refactor metrics to be consistent

Notes for Prysm and Lodestar
