Here’s the current version of the **MEV-Boost Capella Upgrade Guide - for Proposers, Relays and Builders** : [https://flashbots.notion.site/MEV-Boost-Capella-Upgrades-00cea01704794f6eb4f792c55b69c441](https://flashbots.notion.site/MEV-Boost-Capella-Upgrades-00cea01704794f6eb4f792c55b69c441)
tl;dr: proposers just need to run mev-boost v1.5.0+ (released March 14), for relays and builders it’s a bit more involved.
This doc is the main reference and we’ll keep it updated.
