+### Note
+
+`pipenv-setup<3.2` includes pinned versions of `black` and `autopep8` as dependencies. However, most
+projects manage `black` requirements independently from `pipenv-setup`; accordingly, `black` is no
+longer a requirement of `pipenv-setup` after `3.2.0` (instead, include it as an extra as shown
