 All help in providing PRs to close out bug issues is appreciated. Even if that is providing a repo that fully replicates issues. We have very generous contributors that have added these to bug issues which meant another contributor picked up the bug and closed it out.
 
+- Unreleased
+    - Drop support for Python 3.9
+    - Drop support for urllib3 < 2
