 #### Breaking
 - [#1616](https://github.com/FuelLabs/fuel-core/pull/1616) Make `BlockHeader` type a version-able enum
+- [#1614](https://github.com/FuelLabs/fuel-core/pull/#1614): Use the default consensus key regardless of trigger mode. The change is breaking because it removes the `--dev-keys` argument. If the `debug` flag is set, the default consensus key will be used, regardless of the trigger mode.
 - [#1596](https://github.com/FuelLabs/fuel-core/pull/1596) Make `Consensus` type a version-able enum
 - [#1593](https://github.com/FuelLabs/fuel-core/pull/1593) Make `Block` type a version-able enum
 - [#1576](https://github.com/FuelLabs/fuel-core/pull/1576): The change moves the implementation of the storage traits for required tables from `fuel-core` to `fuel-core-storage` crate. The change also adds a more flexible configuration of the encoding/decoding per the table and allows the implementation of specific behaviors for the table in a much easier way. It unifies the encoding between database, SMTs, and iteration, preventing mismatching bytes representation on the Rust type system level. Plus, it increases the re-usage of the code by applying the same blueprint to other tables.
