I'm happy to announce the release of Cython 0.11.2.


(Will be present on the Cython front page in a few days.)

New features:

  * There's now native complex floating point support! C99 complex will 
be used if complex.h is included, otherwise explicit complex arithmetic 
working on all C compilers is used. [Robert Bradshaw]

    cdef double complex a = 1 + 0.3j
    cdef np.ndarray[np.complex128_t, ndim=2] arr = \
        np.zeros(10, np.complex128)

  * Cython can now generate a main()-method for embedding of the Python 
interpreter into an executable (see #289) [Robert Bradshaw]

  * @wraparound directive (another way to disable arr[idx] for negative 
idx) [Dag Sverre Seljebotn]

  * Correct support for NumPy record dtypes with different alignments, 
and "cdef packed struct" support [Dag Sverre Seljebotn]

  * @callspec directive, allowing custom calling convention macros 
[Lisandro Dalcin]

  * Bug fixes and smaller improvements. For the full list, see [1].
