+### Added
+- `exc_info_as_array` and `stack_info_as_array` options are added to `pythonjsonlogger.core.BaseJsonFormatter`.
+  - If `exc_info_as_array` is True (Defualt: False), formatter encode exc_info into an array.
+  - If `stack_info_as_array` is True (Defualt: False), formatter encode stack_info into an array.
