+- bpo-29532: Altering a kwarg dictionary passed to functools.partial()
+  no longer affects a partial object after creation.

+- bpo-22807: Add uuid.SafeUUID and uuid.UUID.is_safe to relay information from
+  the platform about whether generated UUIDs are generated with a
+  multiprocessing safe method.
+
+- bpo-29576: Improve some deprecations in importlib. Some deprecated methods
+  now emit DeprecationWarnings and have better descriptive messages.
+
+- bpo-29534: Fixed different behaviour of Decimal.from_float()
+  for _decimal and _pydecimal. Thanks Andrew Nester.
