Fri Oct 28 12:40:24 UTC 2016 -

- Update to version 0.25.1
  + Bugs fixed
    * Fixes a bug with ``isinstance(o, Exception)`` (Github issue #1496).
    * Fixes bug with ``cython.view.array`` missing utility code in some cases
      (Github issue #1502).
  + Other changes
    * The distutils extension ``Cython.Distutils.build_ext`` has been reverted,
      temporarily, to be ``old_build_ext`` to give projects time to migrate.
      The new build_ext is available as ``new_build_ext``.

Wed Oct 26 01:36:12 UTC 2016 -

- update to version 0.25:
  + Features added
    * def/cpdef methods of cdef classes benefit from Cython's internal function
      implementation, which enables introspection and line profiling for them.
      Implementation sponsored by Turbostream (
    * The distutils extension ``Cython.Distutils.build_ext`` has now been updated
      to use cythonize which properly handles dependencies.  The old extension can
      still be found in ``Cython.Distutils.old_build_ext`` and is now deprecated.
    * Calls to Python functions are faster, following the recent "FastCall"
      optimisations that Victor Stinner implemented for CPython 3.6.
      See and related issues.
    * The new METH_FASTCALL calling convention for PyCFunctions is supported
      in CPython 3.6.  See
    * C++ classes can now have typedef members. STL containers updated with
    * Support for bazel using a the pyx_library rule in //Tools:rules.bzl.
    * Initial support for using Cython modules in Pyston.  Patch by Daetalus.
    * Dynamic Python attributes are allowed on cdef classes if an attribute
      ``cdef dict __dict__`` is declared in the class.  Patch by empyrical.
    * Cython implemented C++ classes can make direct calls to base class methods.
      Patch by empyrical.
    * New directive ``cython.no_gc`` to fully disable GC for a cdef class.
      Patch by Claudio Freire.
    * Buffer variables are no longer excluded from ``locals()``.
      Patch by da-woods.
    * Building f-strings is faster, especially when formatting C integers.
    * for-loop iteration over "std::string".
    * ``libc/math.pxd`` provides ``e`` and ``pi`` as alias constants to simplify
      usage as a drop-in replacement for Python's math module.
    * Speed up cython.inline().
    * Binary lshift operations with small constant Python integers are faster.
    * Some integer operations on Python long objects are faster in Python 2.7.
    * Support for the C++ ``typeid`` operator.
  + Significant Bugs fixed
    * Division of complex numbers avoids overflow by using Smith's method.
    * Some function signatures in ``libc.math`` and ``numpy.pxd`` were incorrect.
      Pach by Michael Seifert.
  + Other changes
    * The "%%cython" IPython/jupyter magic now defaults to the language level of
      the current jupyter kernel.  The language level can be set explicitly with
      "%%cython -2" or "%%cython -3".

Mon Aug 15 14:51:56 UTC 2016 -

- Fix update-alternatives implementation.

Fri Jul 15 15:28:21 UTC 2016 -

- update to version 0.24.1:
  * IPython cell magic was lacking a good way to enable Python 3 code
    semantics. It can now be used as "%%cython -3".
  * Follow a recent change in PEP 492 and CPython 3.5.1 that now
    requires the __aiter__() method of asynchronous iterators to be a
    simple def method instead of an async def method.
  * Coroutines and generators were lacking the __module__ special
  * C++ std::complex values failed to auto-convert from and to Python
    complex objects.
  * Namespaced C++ types could not be used as memory view types due to
    lack of name mangling. Patch by Ivan Smirnov.
  * Assignments between identical C++ types that were declared with
    differently typedefed template types could fail.
  * Rebuilds could fail to evaluate dependency timestamps in C++
    mode. Patch by Ian Henriksen.
  * Macros defined in the distutils compiler option do not require
    values anymore. Patch by Ian Henriksen.
  * Minor fixes for MSVC, Cygwin and PyPy.

- specfile:
  * changed to https for source url
  * updated source url to

Fri Apr  8 05:55:18 UTC 2016 -

- specfile:
  * removed python3-Cython-c++11.patch (included upstream)

- update to version 0.24:
  * Features added
    + PEP 498: Literal String Formatting (f-strings). Original patch
      by Jelle Zijlstra.
    + PEP 515: Underscores as visual separators in number
    + Parser was adapted to some minor syntax changes in Py3.6,
    + The embedded C code comments that show the original source code
      can be discarded with the new directive
    + Cpdef enums are now first-class iterable, callable types in
    + Ctuples can now be declared in pure Python code.
    + Posix declarations for DLL loading and stdio extensions were
      added. Patch by Lars Buitinck.
    + The Py2-only builtins unicode(), xrange(), reduce() and long are
      now also available in compile time DEF expressions when
      compiling with Py3.
    + Exception type tests have slightly lower overhead. This fixes
      ticket 868.
    + @property syntax fully supported in cdef classes, old syntax
    + C++ classes can now be declared with default template
  * Bugs fixed
    + C++ exceptions raised by overloaded C++ operators were not
      always handled. Patch by Ian Henriksen.
    + C string literals were previously always stored as non-const
      global variables in the module. They are now stored as global
      constants when possible, and otherwise as non-const C string
      literals in the generated code that uses them. This improves
      compatibility with strict C compiler options and prevents
      non-const strings literals with the same content from being
      incorrectly merged.
    + Compile time evaluated str expressions (DEF) now behave in a
      more useful way by turning into Unicode strings when compiling
      under Python 3. This allows using them as intermediate values in
      expressions. Previously, they always evaluated to bytes objects.
    + isinf() declarations in libc/math.pxd and numpy/math.pxd now
      reflect the actual tristate int return value instead of using
    + Literal assignments to ctuples avoid Python tuple round-trips in
      some more corner cases.
    + Iteration over dict(...).items() failed to get optimised when
      dict arguments included keyword arguments.
    + cProfile now correctly profiles cpdef functions and methods.

Sun Mar 27 05:54:43 UTC 2016 -

- specfile:
  * removed python3-Cython-prevent_swallowing_StopIteration_return.patch
    included upstream

- update to version 0.23.5:
  * Compile errors and warnings in integer type conversion code. This
    fixes ticket 877. Patches by Christian Neukirchen, Nikolaus Rath,
    Ian Henriksen.
  * Reference leak when "*args" argument was reassigned in closures.
  * Truth-testing Unicode strings could waste time and memory in
  * Return values of async functions could be ignored and replaced by
  * Compiler crash in CPython 3.6.
  * Fix prange() to behave identically to range(). The end condition
    was miscalculated when the range was not exactly divisible by the
  * Optimised all(genexpr)/any(genexpr) calls could warn about unused
    code. This fixes ticket 876.

Fri Feb 12 12:16:49 UTC 2016 -

- Add python3-Cython-prevent_swallowing_StopIteration_return.patch

  * Warning about unused values in a helper macro.

Sun Oct  4 19:18:41 UTC 2015 -

- update to version 0.23.3:
  * Invalid C code for some builtin methods. This fixes ticket 856
  * Incorrect C code in helper functions for PyLong conversion and
    string decoding. This fixes ticket 863, ticket 864 and ticket
    865. Original patch by Nikolaus Rath.
  * Large folded or inserted integer constants could use too small C
    integer types and thus trigger a value wrap-around.
  * The coroutine and generator types of Cython now also register
    directly with the Coroutine and Generator ABCs in the
    backports_abc module if it can be imported. This fixes ticket 870.

Sat Sep 19 14:44:06 UTC 2015 -

- update to version 0.23.2:
  * Compiler crash when analysing some optimised expressions.
  * Coverage plugin was adapted to 4.0 beta 2.
  * C++ destructor calls could fail when '&' operator is overwritten.
  * Incorrect C literal generation for large integers in compile-time
    evaluated DEF expressions and constant folded expressions.
  * Byte string constants could end up as Unicode strings when
    originating from compile-time evaluated DEF expressions.
  * Invalid C code when caching known builtin methods. This fixes
    ticket 860.
  * ino_t in posix.types was not declared as unsigned.
  * Declarations in libcpp/memory.pxd were missing operator!(). Patch
    by Leo Razoumov.
  * Static cdef methods can now be declared in .pxd files.

Sun Aug 23 15:32:41 UTC 2015 -

- update to version 0.23.1:
  * Invalid C code for generators. This fixes ticket 858.
  * Invalid C code for some builtin methods. This fixes ticket 856.
  * Invalid C code for unused local buffer variables. This fixes
    ticket 154.
  * Test failures on 32bit systems. This fixes ticket 857.
  * Code that uses "from xyz import *" and global C struct/union/array
    variables could fail to compile due to missing helper
    functions. This fixes ticket 851.
  * Misnamed PEP 492 coroutine property cr_yieldfrom renamed to
    cr_await to match CPython.
  * Missing deallocation code for C++ object attributes in certain
    extension class hierarchies.
  * Crash when async coroutine was not awaited.
  * Compiler crash on yield in signature annotations and default
    argument values. Both are forbidden now.
  * Compiler crash on certain constructs in finally clauses.
  * Cython failed to build when CPython's pgen is installed.

Mon Aug 10 00:30:34 UTC 2015 -

- update to version 0.23:
  * Features added
    + PEP 492 (async/await) was implemented. See
    + PEP 448 (Additional Unpacking Generalizations) was
      implemented. See
    + Support for 4.0+ can be enabled by adding the plugin
      "Cython.Coverage" to the ".coveragerc" config file.
    + Annotated HTML source pages can integrate (XML) coverage
    + Tracing is supported in nogil functions/sections and module init
    + When generators are used in a Cython module and the module
      imports the modules "inspect" and/or "asyncio", Cython enables
      interoperability by patching these modules during the import to
      recognise Cython's internal generator and coroutine types. This
      can be disabled by C compiling the module with "-D
    + When generators or coroutines are used in a Cython module, their
      types are registered with the Generator and Coroutine ABCs in
      the collections or stdlib module at import time
      to enable interoperability with code that needs to detect and
      process Python generators/coroutines. These ABCs were added in
      CPython 3.5 and are available for older Python versions through
      the backports_abc module on PyPI. See
    + Adding/subtracting/dividing/modulus and equality comparisons
      with constant Python floats and small integers are faster.
    + Binary and/or/xor/rshift operations with small constant Python
      integers are faster.
    + When called on generator expressions, the builtins all(), any(),
      dict(), list(), set(), sorted() and unicode.join() avoid the
      generator iteration overhead by inlining a part of their
      functionality into the for-loop.
    + Keyword argument dicts are no longer copied on function entry
      when they are not being used or only passed through to other
      function calls (e.g. in wrapper functions).
    + The PyTypeObject declaration in cpython.object was extended.
    + The builtin type type is now declared as PyTypeObject in source,
      allowing for extern functions taking type parameters to have the
      correct C signatures. Note that this might break code that uses
      type just for passing around Python types in typed
      variables. Removing the type declaration provides a backwards
      compatible fix.
    + wraparound() and boundscheck() are available as no-ops in pure
      Python mode.
    + Const iterators were added to the provided C++ STL declarations.
    + Smart pointers were added to the provided C++ STL
      declarations. Patch by Daniel Filonik.
    + NULL is allowed as default argument when embedding
      signatures. This fixes ticket 843.
    + When compiling with --embed, the internal module name is changed
      to __main__ to allow arbitrary program names, including those
      that would be invalid for modules. Note that this prevents reuse
      of the generated C code as an importable module.
    + External C++ classes that overload the assignment operator can
      be used. Patch by Ian Henriksen.
    + Support operator bool() for C++ classes so they can be used in
      if statements.
  * Bugs fixed
    + Calling "yield from" from Python on a Cython generator that
      returned a value triggered a crash in CPython. This is now being
      worked around. See
    + Language level 3 did not enable true division (a.k.a. float
`      division) for integer operands.
    + Functions with fused argument types that included a generic
      'object' fallback could end up using that fallback also for
      other explicitly listed object types.
    + Relative cimports could accidentally fall back to trying an
      absolute cimport on failure.
    + The result of calling a C struct constructor no longer requires
      an intermediate assignment when coercing to a Python dict.
    + C++ exception declarations with mapping functions could fail to
      compile when pre-declared in .pxd files.
    + cpdef void methods are now permitted.
    + abs(cint) could fail to compile in MSVC and used sub-optimal
      code in C++. Patch by David Vierra, original patch by Michael
    + Buffer index calculations using index variables with small C
      integer types could overflow for large buffer sizes. Original
      patch by David Vierra.
    + C unions use a saner way to coerce from and to Python dicts.
    + When compiling a module foo.pyx, the directories in sys.path are
      no longer searched when looking for foo.pxd. Patch by Jeroen
    + Memory leaks in the embedding main function were fixed. Original
      patch by Michael Enßlin.
    + Some complex Python expressions could fail to compile inside of
      finally clauses.
    + Unprefixed 'str' literals were not supported as C varargs
    + Fixed type errors in conversion enum types to/from Python. Note
      that this imposes stricter correctness requirements on enum
  * Other changes
    + Changed mangling scheme in header files generated by cdef api
    + Installation under CPython 3.3+ no longer requires a pass of the
      2to3 tool. This also makes it possible to run Cython in Python
      3.3+ from a source checkout without installing it first. Patch
      by Petr Viktorin.
    + (in Tools/) was extended and renamed to (to make it importable) and now works with and
      requires Jedi 0.9. Patch by Tzer-jen Wei.

  * added dependencies needed for test gcc-c++, numpy, numpy-devel
  * added dependency xml
  * (tried running tests, but for some distributions one test still
    failed, so didn't enable the tests)

Sun Jun 21 02:42:59 UTC 2015 -

- update to version 0.22.1:
  * Crash when returning values on generator termination.
  * In some cases, exceptions raised during internal isinstance()
    checks were not propagated.
  * Runtime reported file paths of source files (e.g for profiling and
    tracing) are now relative to the build root directory instead of
    the main source file.
  * Tracing exception handling code could enter the trace function
    with an active exception set.
  * The internal generator function type was not shared across
  * Comparisons of (inferred) ctuples failed to compile.
  * Closures inside of cdef functions returning void failed to
  * Using const C++ references in intermediate parts of longer
    expressions could fail to compile.
  * C++ exception declarations with mapping functions could fail to
    compile when pre-declared in .pxd files.
  * C++ compilation could fail with an ambiguity error in recent
    MacOS-X Xcode versions.
  * C compilation could fail in pypy3.
  * Fixed a memory leak in the compiler when compiling multiple
  * When compiling multiple modules, external library dependencies
    could leak into later compiler runs. Fix by Jeroen Demeyer. This
    fixes ticket 845.

Sat Feb 14 16:33:14 UTC 2015 -

- specfile:
  * Cython->cython in tar ball name on pypi
  * fix update alternatives

- update to version 0.22:
  * 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
  * Looping over reversed(range()) is optimised in the same way as
    range(). Patch by Favian Contreras.
  * 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
  * The logaddexp family of functions in numpy.math now has correct
  * 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.
  * Preliminary support for defining the Cython language with a formal
    grammar. To try parsing your files against this grammar, use the
    --formal_grammar directive. Experimental.
  * _ is no longer considered a cacheable builtin as it could
    interfere with gettext.
  * Cythonize-computed metadata now cached in the generated C files.
  * Several corrections and extensions in numpy, cpython, and libcpp
    pxd files.

- Fix usage of update-alternatives.

Wed Dec 31 20:00:38 UTC 2014 -

- specfile: add python3 again (complains about missing xml package otherwise)

- update to version 0.21.2:
  * Crash when assigning a C value to both a Python and C target at the same time.
  * Automatic coercion from C++ strings to "str" generated incomplete code that
    failed to compile.
  * Declaring a constructor in a C++ child class erroneously required a default
    constructor declaration in the super class.
  * "resize_smart()" in "cpython.array" was broken.
  * Functions in "libcpp.cast" are now declared as "nogil".
  * Some missing C-API declarations were added.
  * Py3 main code in embedding program code was lacking casts.
  * Exception related to distutils "Distribution" class type in pyximport under
    latest CPython 2.7 and 3.4 releases when setuptools is being imported later.

Thu Dec 18 10:45:11 UTC 2014 -

- Remove make dependencies on python3-2to3 and python3, python3-devel
  is sufficient

- Fix cygdb name typo in file list

Tue Dec  9 16:02:19 UTC 2014 -

- Improve update-alternatives.

Sat Dec  6 00:00:33 UTC 2014 -

- specfile: removed Cython-fix-version-detection.patch 
  (got fixed upstream)

- update to version 0.21.1:
  * Features added
    - New cythonize option -a to generate the annotated HTML source view.
    - Missing C-API declarations in cpython.unicode were added.
    - Passing language='c++' into cythonize() globally enables C++ mode
      for all modules that were not passed as Extension objects
      (i.e. only source files and file patterns).
    - Py_hash_t is a known type (used in CPython for hash values).
    - PySlice_*() C-API functions are available from the cpython.slice module.
    - Allow arrays of C++ classes.
  * Bugs fixed
    - Reference leak for non-simple Python expressions in boolean and/or expressions.
    - To fix a name collision and to reflect availability on host
      platforms, standard C declarations [ clock(), time(), struct tm
      and tm* functions ] were moved from posix/time.pxd to a new
      libc/time.pxd. Patch by Charles Blake.
    - Rerunning unmodified modules in IPython's cython support
      failed. Patch by Matthias Bussonier.
    - Casting C++ std::string to Python byte strings failed when
      auto-decoding was enabled.
    - Fatal exceptions in global module init code could lead to
      crashes if the already created module was used later on
      (e.g. through a stale reference in sys.modules or elsewhere).
    - script was not installed on MS-Windows.
  * Other changes
    - Compilation no longer fails hard when unknown compilation
      options are passed. Instead, it raises a warning and ignores
      them (as it did silently before 0.21). This will be changed back
      to an error in a future release.

Sun Nov 09 23:12:00 UTC 2014 - Led <>

- fix bashisms in pre script

Fri Sep 12 10:52:18 UTC 2014 -

- 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-bcolz/python3-bcolz is an example of another package

Thu Sep 11 09:30:20 UTC 2014 -

- Update to 0.21 (2014-09-10)
  * Features added
    * C (cdef) functions allow inner Python functions.
    * Enums can now be declared as cpdef to export their values to
      the module's Python namespace.  Cpdef enums in pxd files export
      their values to their own module, iff it exists.
    * Allow @staticmethod decorator to declare static cdef methods.
      This is especially useful for declaring "constructors" for
      cdef classes that can take non-Python arguments.
    * Taking a ``char*`` from a temporary Python string object is safer
      in more cases and can be done inside of non-trivial expressions,
      including arguments of a function call.  A compile time error
      is raised only when such a pointer is assigned to a variable and
      would thus exceed the lifetime of the string itself.
    * Generators have new properties ``__name__`` and ``__qualname__``
      that provide the plain/qualified name of the generator function
      (following CPython 3.5).  See
    * The ``inline`` function modifier is available as a decorator
      ``@cython.inline`` in pure mode.
    * When cygdb is run in a virtualenv, it enables the same virtualenv
      inside of the debugger. Patch by Marc Abramowitz.
    * PEP 465: dedicated infix operator for matrix multiplication (A @ B).
    * HTML output of annotated code uses Pygments for code highlighting
      and generally received a major overhaul by Matthias Bussonier.
    * IPython magic support is now available directly from Cython with
      the command "%load_ext cython".  Cython code can directly be
      executed in a cell when marked with "%%cython".  Code analysis
      is available with "%%cython -a".  Patch by Martín Gaitán.
    * Simple support for declaring Python object types in Python signature
      annotations.  Currently requires setting the compiler directive
    * New directive ``use_switch`` (defaults to True) to optionally disable
      the optimization of chained if statement to C switch statements.
    * Defines dynamic_cast et al. in ``libcpp.cast`` and C++ heap data
      structure operations in ``libcpp.algorithm``.
    * Shipped header declarations in ``posix.*`` were extended to cover
      more of the POSIX API.  Patches by Lars Buitinck and Mark Peek.
  * Optimizations
    * Simple calls to C implemented Python functions/methods are faster.
      This also speeds up many operations on builtins that Cython cannot
      otherwise optimise.
    * The "and"/"or" operators try to avoid unnecessary coercions of their
      arguments.  They now evaluate the truth value of each argument
      independently and only coerce the final result of the whole expression
      to the target type (e.g. the type on the left side of an assignment).
      This also avoids reference counting overhead for Python values during
      evaluation and generally improves the code flow in the generated C code.
    * The Python expression "2 ** N" is optimised into bit shifting.
    * Cascaded assignments (a = b = ...) try to minimise the number of
      type coercions.
    * Calls to ``slice()`` are translated to a straight C-API call.
  * Bugs fixed
    * Crash when assigning memory views from ternary conditional expressions.
    * Nested C++ templates could lead to unseparated ">>" characters being
      generated into the C++ declarations, which older C++ compilers could
      not parse.
    * Sending SIGINT (Ctrl-C) during parallel cythonize() builds could
      hang the child processes.
    * No longer ignore local setup.cfg files for distutils in pyximport.
      Patch by Martin Teichmann.
    * Taking a ``char*`` from an indexed Python string generated unsafe
      reference counting code.
    * Set literals now create all of their items before trying to add them
      to the set, following the behaviour in CPython.  This makes a
      difference in the rare case that the item creation has side effects
      and some items are not hashable (or if hashing them has side effects,
    * Cython no longer generates the cross product of C functions for code
      that uses memory views of fused types in function signatures (e.g.
      ``cdef func(floating[:] a, floating[:] b)``).  This is considered the
      expected behaviour by most users and was previously inconsistent with
      other structured types like C arrays.  Code that really wants all type
      combinations can create the same fused memoryview type under different
      names and use those in the signature to make it clear which types are
    * Names that were unknown at compile time were looked up as builtins at
      runtime but not as global module names.  Trying both lookups helps with
      globals() manipulation.
    * Fixed stl container conversion for typedef element types.
    * ``obj.pop(x)`` truncated large C integer values of x to ``Py_ssize_t``.
    * ``__init__.pyc`` is recognised as marking a package directory
      (in addition to .py, .pyx and .pxd).
    * Syntax highlighting in ``cython-mode.el`` for Emacs no longer
      incorrectly highlights keywords found as part of longer names.
    * Correctly handle ``from cython.submodule cimport name``.
    * Fix infinite recursion when using super with cpdef methods.
    * No-args ``dir()`` was not guaranteed to return a sorted list.
  * Other changes
    * The header line in the generated C files no longer contains the
      timestamp but only the Cython version that wrote it.  This was
      changed to make builds more reproducible.
    * Removed support for CPython 2.4, 2.5 and 3.1.
    * The licensing implications on the generated code were clarified
      to avoid legal constraints for users.
- Update to 0.20.2 (2014-06-16)
  * Features added
    * Some optimisations for set/frozenset instantiation.
    * Support for C++ unordered_set and unordered_map.
  * Bugs fixed
    * 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 accidentally omitted 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.

- Rename rpmlintrc to %{name}-rpmlintrc.
  Follow the packaging guidelines.

Thu May  8 11:40:51 UTC 2014 -

- Update to version 0.20.1
  * List/Tuple literals multiplied by more than one factor were only multiplied
    by the last factor instead of all.
  * Lookups of special methods (specifically for context managers) could fail
    in Python <= 2.6/3.1.
  * Local variables were erroneously appended to the signature introspection
    of Cython implemented functions with keyword-only arguments under Python 3.
  * In-place assignments to variables with inferred Python builtin/extension
    types could fail with type errors if the result value type was incompatible
    with the type of the previous value.
  * The C code generation order of cdef classes, closures, helper code,
    etc. was not deterministic, thus leading to high code churn.
  * Type inference could fail to deduce C enum types.
  * Type inference could deduce unsafe or inefficient types from integer
    assignments within a mix of inferred Python variables and integer

- Update to version 0.20:
  * 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).
  * The new extension type decorator @cython.no_gc_clear prevents
    objects from being cleared during cyclic garbage collection, thus
    making sure that object attributes are kept alive until deallocation.
  * During cyclic garbage collection, attributes of extension types that
    cannot create reference cycles due to their type (e.g. strings) are
    no longer considered for traversal or clearing.  This can reduce the
    processing overhead when searching for or cleaning up reference cycles.
  * Package compilation (i.e. files) now works, starting
    with Python 3.3.
  * The cython-mode.el script for Emacs was updated.  Patch by Ivan Andrus.
  * An option common_utility_include_dir was added to cythonize() to save
    oft-used utility code once in a separate directory rather than as
    part of each generated file.
  * unraisable_tracebacks directive added to control printing of
    tracebacks of unraisable exceptions.

Tue Oct 22 14:18:37 UTC 2013 -

- 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

    * 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.
