-The resource tracker in the :mod:`multiprocessing` module can now understand
-messages from older versions of itself. This avoids issues with upgrading
-Python while it is running. (Note that such 'in-place' upgrades are not
-tested.)
+The resource tracker in the :mod:`multiprocessing` module now uses the
+original communication protocol, as in Python 3.14.0 and below,
+by default.
+This avoids issues with upgrading Python while it is running.
+(Note that such 'in-place' upgrades are not tested.)
+The tracker remains compatible with subprocesses that use new protocol
+(that is, subprocesses using Python 3.13.10, 3.14.1 and 3.15).
