Upgrade Notes

This release changes the Redis storage key for Capella execution payloads (where the proposer API looks up the getPayload response). You should update both builder-API and proposer-API simultaneously! See PR #448 for more details.
We recommend to run prio-load-balancer v0.9 or later (but it is not required)
This release significantly improves Redis performance and reduces the number of simulations ⚡
