v1.12

• Docker Image: flashbots/mev-boost:1.12
• Full Changelog: v1.11...v1.12

This release allows validators to be grouped into mux groups, each with their own relay set, timeouts, and timing game configurations via the global config file. This enables node operators running multiple validator sets to route getHeader requests to different relays per group.

Example Configuration

...
mux:
  - id: "lido"
    validator_pubkeys:
      - "0x8a1d7b..."
    timeout_get_header_ms: 900
    late_in_slot_time_ms: 1500
    relays:
      - url: https://0xpubkey@lido-relay.example.com
        enable_timing_games: true
        target_first_request_ms: 200
        frequency_get_header_ms: 100

  - id: "rocket-pool"
    validator_pubkeys:
      - "0x8d1d7b..."
    relays:
      - url: https://0xpubkey@rocketpool-relay.example.com
