-   Do *NOT* add changelog entries here!
+- We had to revert the recursive feature for ``attr.evolve()`` because it broke some use-cases -- sorry!
+  `#806 <https://github.com/python-attrs/attrs/issues/806>`_
+- Python 3.4 is now blocked using packaging metadata because ``attrs`` can't be imported on it anymore.
+  To ensure that 3.4 users can keep installing  ``attrs`` easily, we will `yank <https://pypi.org/help/#yanked>`_ 21.1.0 from PyPI.
+  This has **no** consequences if you pin ``attrs`` to 21.1.0.
+  `#807 <https://github.com/python-attrs/attrs/issues/807>`_
