 #### Breaking
 
+- [#701](https://github.com/FuelLabs/fuel-vm/pull/701): Wrapped `ConsensusParameters` and `GasCosts` into an enum to support versioning. Moved `block_gas_limit` from `fuel_core_chain_config::ChainConfig` to `ConsensusPataremeters`. Reduced default `MAX_SIZE` to be [110kb](https://github.com/FuelLabs/fuel-core/pull/1761) and `MAX_CONTRACT_SIZE` to be [100kb](https://github.com/FuelLabs/fuel-core/pull/1761).
 - [#692](https://github.com/FuelLabs/fuel-vm/pull/692): Add GTF getters for tx size and address.
 - [#698](https://github.com/FuelLabs/fuel-vm/pull/698): Store input, output and witness limits to u16, while keeping the values limited to 255.
