…osmos#9498) * chore(types): add sdk.Context.Codec and deprecate JSONCodec * Use clientContext.Codec rather than JSONCodec everywhere * update tests to use clientContext.Codec * added a note that EncodingConfig.Marshaler will be renamed to Codec * update changelog * fix tests to use clientCtx.WithCodec instead of WithJSONCodec * fix genutil build * Update simapp/params/encoding.go Co-authored-by: Amaury <1293565 [email protected]> Co-authored-by: Amaury <1293565 [email protected]>
