0.19.1 (2013-05-11)
===================

Features added
--------------

* 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.

Bugs fixed
----------

* ``isinstance(X, type)`` failed to get optimised into a call to
  ``PyType_Check()``, as done for other builtin types.

* A spurious "from datetime cimport *" was removed from the \ 
"cpython"
  declaration package. This means that the "datetime" declarations
  (added in 0.19) are no longer available directly from the "cpython"
  namespace, but only from "cpython.datetime". This is the correct
  way of doing it because the declarations refer to a standard library
  module, not the core CPython C-API itself.

* The C code for extension types is now generated in topological order
  instead of source code order to avoid C compiler errors about missing
  declarations for subtypes that are defined before their parent.

* The ``memoryview`` type name no longer shows up in the module dict of
  modules that use memory views.  This fixes trac ticket 775.

* Regression in 0.19 that rejected valid C expressions from being used
  in C array size declarations.

* In C++ mode, the C99-only keyword ``restrict`` could accidentally be
  seen by the GNU C++ compiler. It is now specially handled for both
  GCC and MSVC.

* Testing large (> int) C integer values for their truth value could fail
  due to integer wrap-around.

Update to 0.19:

0.19 (2013-04-19)
=================

Features added
--------------

* New directives ``c_string_type`` and ``c_string_encoding`` to more easily
  and automatically convert between C strings and the different Python string
  types.

* The extension type flag ``Py_TPFLAGS_HAVE_VERSION_TAG`` is enabled by default
  on extension types and can be disabled using the ``type_version_tag`` compiler
  directive.

* EXPERIMENTAL support for simple Cython code level line tracing.  Enabled by
  the "linetrace" compiler directive.

* Cython implemented functions make their argument and return type annotations
  available through the ``__annotations__`` attribute (PEP 3107).

* Access to non-cdef module globals and Python object attributes is faster.

* ``Py_UNICODE*`` coerces from and to Python unicode strings.  This is
  helpful when talking to Windows APIs, which use compatible wchar_t
  arrays for strings.  Note that the ``Py_UNICODE`` type is otherwise
  deprecated as of CPython 3.3.

* ``isinstance(obj, basestring)`` is optimised.  In Python 3 it only tests
  for instances of ``str`` (i.e. Py2 ``unicode``).

* The ``basestring`` builtin is mapped to ``str`` (i.e. Py2 ``unicode``) when
  compiling the generated C code under Python 3.

* Closures use freelists, which can speed up their creation quite substantially.
  This is also visible for short running generator expressions, for example.

* A new class decorator ``@cython.freelist(N)`` creates a static freelist of N
  instances for an extension type, thus avoiding the costly allocation step if
  possible. This can speed up object instantiation by 20-30% in suitable
  scenarios. Note that freelists are currently only supported for base types,
  not for types that inherit from others.

* Fast extension type instantiation using the ``Type.__new__(Type)`` idiom has
  gained support for passing arguments.  It is also a bit faster for types defined
  inside of the module.

* The Python2-only dict methods ``.iter*()`` and ``.view*()`` (requires Python 2.7)
  are automatically mapped to the equivalent keys/values/items methods in Python 3
  for typed dictionaries.

* 2-value slicing of unknown objects passes the correct slice when the ``getitem``
  protocol is used instead of the ``getslice`` protocol (especially in Python 3),
  i.e. ``None`` values for missing bounds instead of ``[0,maxsize]``.  It is also
  a bit faster in some cases, e.g. for constant bounds.  This fixes trac ticket 636.

* Slicing unicode strings, lists and tuples is faster.

* list.append() is faster on average.

* ``raise Exception() from None`` suppresses the exception context in Py3.3.

* Py3 compatible ``exec(tuple)`` syntax is supported in Py2 code.

* Keyword arguments are supported for cdef functions.

* External C++ classes can be declared nogil.  Patch by John Stumpo.  This fixes
  trac ticket 805.

Bugs fixed
----------

* Cascaded assignments of None values to extension type variables failed with
  a ``TypeError`` at runtime.

* The ``__defaults__`` attribute was not writable for Cython implemented
  functions.

* Default values of keyword-only arguments showed up in ``__defaults__`` instead
  of ``__kwdefaults__`` (which was not implemented).  Both are available for
  Cython implemented functions now, as specified in Python 3.x.

* ``yield`` works inside of ``with gil`` sections.  It previously lead to a crash.
  This fixes trac ticket 803.

* Static methods without explicitly named positional arguments (e.g. having only
  ``*args``) crashed when being called.  This fixes trac ticket 804.

* ``dir()`` without arguments previously returned an unsorted list, which now
  gets sorted as expected.

* ``dict.items()``, ``dict.keys()`` and ``dict.values()`` no longer return lists
  in Python 3.

* Exiting from an ``except-as`` clause now deletes the exception in Python 3 mode.

* The declarations of ``frexp()`` and ``ldexp()`` in ``math.pxd`` were incorrect.

Update to 0.18:

0.18 (2013-01-28)
=================

Features added
--------------

* Named Unicode escapes ("\N{...}") are supported.

* Python functions/classes provide the special attribute "__qualname__"
  as defined by PEP 3155.

* Added a directive ``overflowcheck`` which raises an OverflowException when
  arithmetic with C ints overflow.  This has a modest performance penalty, but
  is much faster than using Python ints.

* Calls to nested Python functions are resolved at compile time.

* Type inference works across nested functions.

* ``py_bytes_string.decode(...)`` is optimised.

* C ``const`` declarations are supported in the language.

Bugs fixed
----------

* Automatic C++ exception mapping didn't work in nogil functions (only in
  "with nogil" blocks).

0.17.4 (2013-01-03)
===================

Bugs fixed
----------

* Garbage collection triggered during deallocation of container classes could \ 
lead to a double-deallocation.

Log message:
Update to 0.17.3:

0.17.3:

Bugs fixed
----------

* During final interpreter cleanup (with types cleanup enabled at compile
  time), extension types that inherit from base types over more than one
  level that were cimported from other modules could lead to a crash.
* Weak-reference support in extension types (with a "cdef __weakref__"
  attribute) generated incorrect deallocation code.
* In CPython 3.3, converting a Unicode character to the Py_UNICODE type
  could fail to raise an overflow for non-BMP characters that do not fit
  into a wchar_t on the current platform.
* Negative C integer constants lost their longness suffix in the generated
  C code.

0.17.2:

Features added
--------------

* ``cythonize()`` gained a best effort compile mode that can be used to
simply ignore .py files that fail to compile.

Bugs fixed
----------

* Replacing an object reference with the value of one of its cdef
attributes could generate incorrect C code that accessed the object after
deleting its last reference.

* C-to-Python type coercions during cascaded comparisons could generate
invalid C code, specifically when using the 'in' operator.

* "obj[1,]" passed a single integer into the item getter instead of a \ 
tuple.

* Cyclic imports at module init time did not work in Py3.

* The names of C++ destructors for template classes were built incorrectly.

* In pure mode, type casts in Cython syntax and the C ampersand operator
are now rejected. Use the pure mode replacements instead.

* In pure mode, C type names and the sizeof() function are no longer
recognised as such and can be used as normal Python names.

* The extended C level support for the CPython array type was declared too
late to be used by user defined classes.

* C++ class nesting was broken.

* Better checking for required nullary constructors for stack-allocated C++
instances.

* Remove module docstring in no-docstring mode.

* Fix specialization for varargs function signatures.

* Fix several compiler crashes.
