 - [2377](https://github.com/FuelLabs/fuel-core/pull/2377): Add more errors that can be returned as responses when using protocol `/fuel/req_res/0.0.2`. The errors supported are `ProtocolV1EmptyResponse` (status code `0`) for converting empty responses sent via protocol `/fuel/req_res/0.0.1`, `RequestedRangeTooLarge`(status code `1`) if the client requests a range of objects such as sealed block headers or transactions too large, `Timeout` (status code `2`) if the remote peer takes too long to fulfill a request, or `SyncProcessorOutOfCapacity` if the remote peer is fulfilling too many requests concurrently.
+- [2233](https://github.com/FuelLabs/fuel-core/pull/2233): Introduce a new column `modification_history_v2` for storing the modification history in the historical rocksDB. Keys in this column are stored in big endian order. Changed the behaviour of the historical rocksDB to write changes for new block heights to the new column, and to perform lookup of values from the `modification_history_v2` table first, and then from the `modification_history` table, performing a migration upon access if necessary.
