 ### Changed
 
+- [#1468](https://github.com/FuelLabs/fuel-core/pull/1468): Bumped version of the `fuel-vm` to `v0.40.0`. It brings some breaking changes into consensus parameters API because of changes in the underlying types.
 - [#1460](https://github.com/FuelLabs/fuel-core/pull/1460): Change tracking branch from main to master for releasy tests.
 - [#1440](https://github.com/FuelLabs/fuel-core/pull/1440): Don't report reserved nodes that send invalid transactions.
 - [#1439](https://github.com/FuelLabs/fuel-core/pull/1439): Reduced memory BMT consumption during creation of the header.
