+* This is the second typed release with a lot of improvements under the hood.
+
+* General:
+  - Remove python 3.6 support
+  - Remove distutils inline with deprecation in standard library.
+  - Update sphinx to 4.1.12 and use autodoc-typehints.
+
+* Typing:
+  - Add types to ALL functions.
+  - Ensure py.typed is collected.
+  - Increase mypy strictness with disallow_untyped_defs, warn_redundant_casts, warn_unreachable.
+  - Use typing.NamedTuple and typing.OrderedDict now 3.6 dropped.
+  - Remove use of typing.TypeGuard until later release, to allow dependant libs time to update.
+  - Tracking issue: https://github.com/gitpython-developers/GitPython/issues/1095
+
+* Runtime improvements:
+  - Add clone_multi_options support to submodule.add()
+  - Delay calling get_user_id() unless essential, to support sand-boxed environments.
+  - Add timeout to handle_process_output(), in case thread.join() hangs.
