- Add python-numpy as BuildRequires to have more complete test coverage
- Fix doctests in 32-bit environment (fix-32bit.patch)
- Update to 0.22:
Features added
* C functions can coerce to Python functions, which allows passing them
around as callable objects.
* C arrays can be assigned by value and auto-coerce from Python iterables
and to Python lists (and tuples).
* Extern C functions can now be declared as cpdef to export them to
the module's Python namespace. Extern C functions in pxd files export
their values to their own module, iff it exists.
* Anonymous C tuple types can be declared as (ctype1, ctype2, ...).
* PEP 479: turn accidental StopIteration exceptions that exit generators
into a RuntimeError, activated with future import "generator_stop".
See http://legacy.python.org/dev/peps/pep-0479/
* Looping over ``reversed(range())`` is optimised in the same way as
``range()``. Patch by Favian Contreras.
Bugs fixed
* Mismatching 'except' declarations on signatures in .pxd and .pyx files failed
to produce a compile error.
* Failure to find any files for the path pattern(s) passed into ``cythonize()``
is now an error to more easily detect accidental typos.
* The ``logaddexp`` family of functions in ``numpy.math`` now has correct
declarations.
* In Py2.6/7 and Py3.2, simple Cython memory views could accidentally be
interpreted as non-contiguous by CPython, which could trigger a CPython
bug when copying data from them, thus leading to data corruption.
See CPython issues 12834 and 23349.

- Add Cython-fix-version-detection.patch
This is a patch from upstream that restores version information whose removal is preventing several packages from correctly detecting Cython's presence. It is already merged upstream and so should be in the next release.
Note that despite what upstream says, python-tables/python3-tables is NOT the only package affected by this, which is why the patch is going here instead of python-tables/python3-tables.
python-bcolz/python3-bcolz is an example of another package affected.

- Update to version 0.20.2:
* Some optimisations for set/frozenset instantiation.
* Support for C++ unordered_set and unordered_map.
* Access to attributes of optimised builtin methods (e.g.
``[].append.__name__``) could fail to compile.
* Memory leak when extension subtypes add a memory view as attribute
to those of the parent type without having Python object attributes
or a user provided dealloc method.
* Compiler crash on readonly properties in "binding" mode.
* Auto-encoding with ``c_string_encoding=ascii`` failed in Py3.3.
* Crash when subtyping freelist enabled Cython extension types with
Python classes that use ``__slots__``.
* Freelist usage is restricted to CPython to avoid problems with other
Python implementations.
* Memory leak in memory views when copying overlapping, contiguous slices.
* Format checking when requesting non-contiguous buffers from
``cython.array`` objects was disabled in Py3.
* C++ destructor calls in extension types could fail to compile in clang.
* Buffer format validation failed for sequences of strings in structs.
* Docstrings on extension type attributes in .pxd files were rejected.
- add python-xml to build requirements for testsuite

* Support for CPython 3.4.
* Support for calling C++ template functions.
* yield is supported in finally clauses.
* The C code generated for finally blocks is duplicated for each exit
case to allow for better optimisations by the C compiler.
* Cython tries to undo the Python optimisationism of assigning a bound
method to a local variable when it can generate better code for the
direct call.
* Constant Python float values are cached.
* String equality comparisons can use faster type specific code in
more cases than before.
* String/Unicode formatting using the '%' operator uses a faster
C-API call.
* bytearray has become a known type and supports coercion from and
to C strings. Indexing, slicing and decoding is optimised. Note that
this may have an impact on existing code due to type inference.
* Using cdef basestring stringvar and function arguments typed as
basestring is now meaningful and allows assigning exactly
str and unicode objects, but no subtypes of these types.
* Support for the __debug__ builtin.
* Assertions in Cython compiled modules are disabled if the running
Python interpreter was started with the "-O" option.
* Some types that Cython provides internally, such as functions and
generators, are now shared across modules if more than one Cython
implemented module is imported.
* The type inference algorithm works more fine granular by taking the
results of the control flow analysis into account.
* A new script in bin/cythonize provides a command line frontend
to the cythonize() compilation function (including distutils build).

- update to 0.19.2:
* Some standard declarations were fixed or updated, including the previously
incorrect declaration of ``PyBuffer_FillInfo()`` and some missing bits in
``libc.math``.
* Heap allocated subtypes of ``type`` used the wrong base type struct at the
C level.
* Calling the unbound method dict.keys/value/items() in dict subtypes could
call the bound object method instead of the unbound supertype method.
* "yield" wasn't supported in "return" value expressions.
* Using the "bint" type in memory views lead to unexpected results.
It is now an error.
* Assignments to global/closure variables could catch them in an illegal state
while deallocating the old value.

- update to 0.19.1:
* Completely empty C-API structs for extension type slots (protocols like
number/mapping/sequence) are no longer generated into the C code.
* Docstrings that directly follow a public/readonly attribute declaration
in a cdef class will be used as docstring of the auto-generated property.
This fixes ticket 206.
* The automatic signature documentation tries to preserve more semantics
of default arguments and argument types. Specifically, ``bint`` arguments
now appear as type ``bool``.
* A warning is emitted when negative literal indices are found inside of
a code section that disables ``wraparound`` handling. This helps with
fixing invalid code that might fail in the face of future compiler
optimisations.
* Constant folding for boolean expressions (and/or) was improved.
* Added a build_dir option to cythonize() which allows one to place
the generated .c files outside the source tree.
