- * Fix default of `create_additions` to always be false [CVE-2020-10663]
+ * Fix default of `create_additions` to always be `false` for `JSON(user_input)`

+   serialization of trusted data. [CVE-2020-10663]
  * Fix passing args all #to_json in json/add/*.
  * Fix encoding issues
  * Fix issues of keyword vs positional parameter
