  9. def getCustomKeySerializer[A](ser: (Formats) => (PartialFunction[String, A], PartialFunction[Any, String]))(implicit arg0: ClassTag[A], arg1: Manifest[A]): CustomKeySerializer[A]

    Json4s up to 3.7-M5 needs Manifest, later versions need ClassTag

  10. def getCustomSerializer[A](ser: (Formats) => (PartialFunction[JValue, A], PartialFunction[Any, JValue]))(implicit arg0: ClassTag[A], arg1: Manifest[A]): CustomSerializer[A]

    Json4s up to 3.7-M5 needs Manifest, later versions need ClassTag

  11. def getStrictSerializationFormat(typeHints: ShortTypeHints): Formats

    Json4s formats.withStrictMapExtraction does not yet exists in 3.7-M5
