+Highlights
+==========
 
-This release has the following aims:
+Python 3 compatibility
+----------------------
 
-* Python 3 compatibility
-* :pep:`3118` compatibility
+This is the first NumPy release which is compatible with Python 3. Support for
+Python 3 and Python 2 is done from a single code base. Extensive notes on
+changes can be found at
+`<http://projects.scipy.org/numpy/browser/trunk/doc/Py3K.txt>`_.
 
+Porting of SciPy to Python 3 is expected to be completed soon.
 
-Highlights
-==========
+:pep:`3118` compatibility
+-------------------------
 
+The new buffer protocol described by PEP 3118 is fully supported in this
+version of Numpy. On Python versions >= 2.6 Numpy arrays expose the buffer
+interface, and array(), asarray() and other functions accept new-style buffers
+as input.

 histogram
 ---------
+
 After a two years transition period, the old behavior of the histogram function
 has been phased out, and the "new" keyword has been removed.

+correlate
+---------
+
+The old behavior of correlate was deprecated in 1.4.0, the new behavior (the
+usual definition for cross-correlation) is now the default.
