This is a maintenance release for Vouch 1.8.x. Changes include:
- update go-eth2-client dependency (compatibility with lodestar 1.20.0)
- use proposer V3 APIs
- do not error if proposal graffiti has been altered
This update is recommended only if you run lodestar 1.20.0, or if you are seeing errors with attempting to generate proposals to to the consensus client rewriting graffiti. Outside of these situations upgrading is optional.
