Log Message:
py-jsonpickle: updated to 1.4.1

v1.4.1
* Patch release for Python 3.8 `importlib_metadata` support.

v1.4
* Python 3.8 support.
* ``jsonpickle.encode`` now supports the standard ``indent``
  and ``separators`` arguments, and passes them through to the
  active JSON backend library.
* We now include a custom handler for `array.array` objects.
* Dict key order is preserved when pickling dictionaries on Python3.
* Improved serialization of dictionaries with non-string keys.
  Previously, using an enum that was both the key and a value in
  a dictionary could end up with incorrect references to other
  objects.  The references are now properly maintained for dicts
  with object keys that are also referenced in the dict's values.
* Improved serialization of pandas.Series objects.

v1.3
* Improved round tripping of default dicts.
* Better support for cyclical references when encoding with
  ``unpicklable=False``.
