 plistlib
 --------
 
-:mod:`plistlib` now supports binary plist files, and offers the common
-``load``/``loads``/``dump``/``dumps`` API pattern for serialization formats
-(Contributed by Ronald Oussoren and others in :issue:`14455`).
+:mod:`plistlib` now has an API that is similar to the standard pattern for
+stdlib serialization protocols, with new :func:`~plistlib.load`,
+:func:`~plistlib.dump`, :func:`~plistlib.loads`, and :func:`~plistlib.dumps`
+functions.  (The older API is now deprecated.)  In addition to the already
+supported XML plist format (:data:`~plistlib.FMT_XML`), it also now supports
+the binary plist format (:data:`~plistlib.FMT_BINARY`).  (Contributed by Ronald
+Oussoren and others in :issue:`14455`).
