* Fri Jul 15 2016 arun@gmx.de
- 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
attribute.
* 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 files.pythonhosted.org
* Fri Apr 08 2016 arun@gmx.de
- 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. https://www.python.org/dev/peps/pep-0498/
+ PEP 515: Underscores as visual separators in number
literals. https://www.python.org/dev/peps/pep-0515/
+ Parser was adapted to some minor syntax changes in Py3.6,
e.g. https://bugs.python.org/issue9232
+ The embedded C code comments that show the original source code
can be discarded with the new directive
emit_code_comments=False.
+ Cpdef enums are now first-class iterable, callable types in
Python.
+ 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
deprecated.
+ C++ classes can now be declared with default template
parameters.
* 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
bint.
+ 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 2016 arun@gmx.de
- 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
Py3.3+.
* Return values of async functions could be ignored and replaced by
None.
* 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
step.
* Optimised all(genexpr)/any(genexpr) calls could warn about unused
code. This fixes ticket 876.
* Fri Feb 12 2016 toddrme2178@gmail.com
- Add python3-Cython-prevent_swallowing_StopIteration_return.patch
to fix compatibility with python 3.5.1. Should be included in
next upstream release.
* Thu Jan 28 2016 rguenther@suse.com
- Add python3-Cython-c++11.patch to fix complex math testcase compile

* Sat Oct 10 2015 arun@gmx.de
- update to version 0.23.4:
* Memory leak when calling Python functions in PyPy.
* Compilation problem with MSVC in C99-ish mode.
* Warning about unused values in a helper macro.
* Sun Oct 04 2015 arun@gmx.de
- update to version 0.23.3:
* Invalid C code for some builtin methods. This fixes ticket 856
again.
* 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 2015 arun@gmx.de
- update to version 0.23.2:
* Compiler crash when analysing some optimised expressions.
* Coverage plugin was adapted to coverage.py 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 2015 arun@gmx.de
- 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 2015 arun@gmx.de
- update to version 0.23:
* Features added
+ PEP 492 (async/await) was implemented. See
https://www.python.org/dev/peps/pep-0492/
+ PEP 448 (Additional Unpacking Generalizations) was
implemented. See https://www.python.org/dev/peps/pep-0448/
+ Support for coverage.py 4.0+ can be enabled by adding the plugin
"Cython.Coverage" to the ".coveragerc" config file.
+ Annotated HTML source pages can integrate (XML) coverage
reports.
+ Tracing is supported in nogil functions/sections and module init
code.
+ 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
CYTHON_PATCH_ASYNCIO=0" or "-D CYTHON_PATCH_INSPECT=0"
+ When generators or coroutines are used in a Cython module, their
types are registered with the Generator and Coroutine ABCs in
the collections or collections.abc 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
https://bugs.python.org/issue24018
+ 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 https://bugs.python.org/issue23996
+ 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
Enßlin.
+ 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
Demeyer.
+ 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
arguments.
+ Fixed type errors in conversion enum types to/from Python. Note
that this imposes stricter correctness requirements on enum
declarations.
* Other changes
+ Changed mangling scheme in header files generated by cdef api
declarations.
+ 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.
+ jedi-typer.py (in Tools/) was extended and renamed to
jedityper.py (to make it importable) and now works with and
requires Jedi 0.9. Patch by Tzer-jen Wei.

* 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, ...).

* 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
