 ### Changed
 
+- [#1397](https://github.com/FuelLabs/fuel-core/pull/1397): Improved keygen. Created a crate to be included from forc plugins and upgraded internal library to drop requirement of protoc to build
 - [#1349](https://github.com/FuelLabs/fuel-core/pull/1349): Updated peer-to-peer transactions API to support multiple blocks in a single request, and updated block synchronization to request multiple blocks based on the configured range of headers.
 - [#1380](https://github.com/FuelLabs/fuel-core/pull/1380): Add preliminary, hard-coded config values for heartbeat peer reputation, removing `todo`.
 - [#1377](https://github.com/FuelLabs/fuel-core/pull/1377): Remove `DiscoveryEvent` and use `KademliaEvent` directly in `DiscoveryBehavior`.
