``np.random.choice`` raised an error when the arguments described an empty
distribution. This has been fixed so that e.g.
``np.random.choice([],0) == np.array([],dtype=float64)``.

Newline needed here

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
NumPy comes bundled with a minimal implementation of lapack for systems without
a lapack library installed, under the name of ``lapack_lite``. This has been
upgraded from LAPACK 3.0.0 (June 30, 1999) to LAPACK 3.2.2 (June 30, 2010). See
the `LAPACK changelogs`_ for details on the all the changes this entails.

While no new features are exposed through ``numpy``, this fixes some bugs
regarding "workspace" sizes, and in some places may use faster algorithms.
