     * The signature of `NewSigVerificationDecorator` has been changed to accept a `x/tx/signing.HandlerMap`.
     * The signature of `VerifySignature` has been changed to accept a `x/tx/signing.HandlerMap` and other structs from `x/tx` as arguments.
     * The signature of `NewTxConfigWithTextual` has been deprecated and its signature changed to accept a `SignModeOptions`.
