maintenance release.
+Two new environment variables for debug mode
+--------------------------------------------
+
+In debug mode, the ``[xxx refs]`` statistic is not written by default, the
+:envvar:`PYTHONSHOWREFCOUNT` environment variable now must also be set.
+(Contributed by Victor Stinner; :issue:`31733`.)
+
+When Python is compiled with ``COUNT_ALLOC`` defined, allocation counts are no
+longer dumped by default anymore: the :envvar:`PYTHONSHOWALLOCCOUNT` environment
+variable must now also be set. Moreover, allocation counts are now dumped into
+stderr, rather than stdout. (Contributed by Victor Stinner; :issue:`31692`.)
+
+.. versionadded:: 2.7.15
