+Subject: [PATCH] Disable logger validation during unit testing
+
+The unit tests set format to "dummy", which gets rejected by Python 3.8
+by default due to newly added validation here:
+
+  https://github.com/python/cpython/commit/18fb1fb943b7dbd7f8a76017ee2a67ef13effb85
+
+We can skip this and restore old behavior by disabling validation.
