+The signature of the extension interface `HasRegisterInterfaces` has been changed to accept a `cosmossdk.io/core/registry.LegacyRegistry` instead of a `codec.InterfaceRegistry`.   `HasRegisterInterfaces` is now a part of `cosmossdk.io/core/appmodule`.  Modules should update their `HasRegisterInterfaces` implementation to accept a `cosmossdk.io/core/registry.LegacyRegistry` interface.
