+* Direct imports from the following modules is deprecated. All testing related
+  imports should come from `numpy.testing`.
+  * `np.testing.utils`
+  * `np.testing.decorators`

+  * `np.testing.noseclasses`
+  * `np.core.umath_tests`
+
+* Giving a generator to `np.sum` is now deprecated. This was undocumented, but
+  worked. Previously, it would calculate the sum of the generator expression.
+  In the future, it might return a different result. Use `np.sum(np.from_iter(generator))`
+  or the built-in Python `sum` instead.

+* Users of the C-API should call ``PyArrayResolveWriteBackIfCopy`` or
+  ``PyArray_DiscardWritbackIfCopy`` on any array with the ``WRITEBACKIFCOPY``
+  flag set, before the array is deallocated. A deprecation warning will be
+  emitted if those calls are not used when needed.
+
+* Users of ``nditer`` should use the nditer object as a context manager
+  anytime one of the iterator operands is writeable, so that numpy can
+  manage writeback semantics, or should call ``it.close()``. A
+ `RuntimeWarning` will be emitted otherwise in these cases. Users of the C-API
+  should call ``NpyIter_Close`` before ``NpyIter_Deallocate``.
