-* The `x/params` module has been deprecated in favour of each module housing and providing way to modify their parameters. Each module that has parameters that are changeable during runtime have an authority, the authority can be a module or user account. The Cosmos SDK team recommends migrating modules away from using the param module. An example of how this could look like can be found [here](https://github.com/cosmos/cosmos-sdk/pull/12363).

 Instead, the SDK uses [`buf`](https://buf.build). Clients should have their own [`buf.yaml`](https://docs.buf.build/configuration/v1/buf-yaml) with `buf.build/cosmos/cosmos-sdk` as dependency, in order to avoid having to copy paste these files.
