+Bugs Fixed
+----------
+
+* Eliminate noise in logs under Python 3.13 when Python garbage collection
+  decides to delay destruction of objects until a second phase, resulting in
+  the `wsgi.errors` log object being accessed after the request had been
+  completed and the log object marked as invalid. This resulted due to changes
+  in garbage collection behaviour in Python 3.13.
