This is an alpha feature release for Vouch.

This release is not suitable for running on mainnet. Please only run this release on testnets.

Major changes in this release include:

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
alter logic for determining sync committee eligible accounts
enable first strategies to be defined for beaconblockheader and signedbeaconblock
remove note about additional options required for Lodestar clients

Major changes in prior alpha releases include:

improvements to memory and CPU usage, especially with high numbers of validators
add beaconblockproposer.builder-boost-factor
allow Vouch to act as an MEV-boost client for non-Vouch validators
increase proposal performance with new validator REST APIs
allow Vouch to start with some consensus nodes unavailable
reduce time and memory spent obtaining and verifying accounts

Notes for Prysm and Lodestar

Prysm must be started with the --enable-debug-rpc-endpoints option for Vouch to operate correctly.

Below no longer needed for Lodestar v1.20 onwards.
~~## Lodestar~~

~~Lodestar must be started with the --rest.namespace=beacon,config,events,node,validator,lightclient,debug option for Vouch to operate correctly.~~
