+- Installing Falcon 4.0.0 unexpectly copies many unintended directories from the
+  source tree to the venv's ``site-packages``. This issue has been rectified, and
+  our CI has been extended with new tests (that verify what is actually installed
+  from the distribution) to make sure this regression does not resurface. (`#2384 <https://github.com/falconry/falcon/issues/2384>`__)
