# Prysm Gas Limit Usage Overview

This document provides a summary of gas limit settings and recommendations for Prysm releases.

### Release `v5.1.2` and Earlier
- If you're using this version, update to `v5.2.0` immediately to ensure MEV-Boost and builder blocks work correctly.
- **Important**: Without upgrading, you will produce only local blocks once the gas limit exceeds 30M.

### Release `v5.2.0`
- Gas limit can **ONLY** be set using the validator client’s `--suggested-gas-limit` flag, which applies to all validators in your setup.
- Gas limit configuration through `--proposer-settings-file` is **not supported** in this release.
- The beacon node will use builder blocks regardless of gas limit mismatches.
- **Recommendation**: Use the `--suggested-gas-limit` flag for gas limit changes.

### Upcoming in `v5.2.1`
- Gas limit settings via `--proposer-settings-file` (if set) will take precedence over other configurations.
- The builder's gas limit check will be fixed, ensuring the beacon node defaults to the local block if there’s a mismatch with the builder.
