v0.2.0

:Date: January 1, 2021

The changes since Manim Community release v0.1.1 are listed below.

Breaking Changes
================

- Remove all CONFIG dictionaries and all calls to ``digest_config`` and allow
  passing options directly to the constructor of the corresponding classes (:pr:`783`).

  Practically, this means that old constructions using ``CONFIG`` like::

      class SomeMobject(Thing):
          CONFIG = {
              "my_awesome_property": 42
          }

  where corresponding objects were then instantiated as ``my_mobject = SomeMobject()``
  should now be created simply using ``my_mobject = SomeMobject(my_awesome_property=42)``.

- Remove old syntax for animating mobject methods by passing the methods and arguments to ``self.play``,
  and use a new syntax featuring the ``animate`` property (:pr:`881`).

  For example: the old-style ``play`` call
  ::

      self.play(my_square.shift, LEFT)

  should be replaced with the new following call using the ``animate`` property::

      self.play(my_square.animate.shift(LEFT))
