| <ul> |
| <li>Python 3 support:</li> |
| <ul> |
| <li>All the current Boost.Python test cases passed. Extension modules using |
| Boost.Python expected to support Python 3 smoothly.</li> |
| <li>Introduced <code>object.contains</code> where <code>x.contains(y)</code> |
| is equivalent to Python code <code>y in x</code>. |
| Now <code>dict.has_key</code> is just a wrapper of <code>object.contains</code>. |
| </li> |
| <li>When building against Python 3, <code>str.decode</code> will be removed.</li> |
| <li>When building against Python 3, the original signature of <code>list.sort</code>, which is: |
| <pre>void sort(object_cref cmpfunc);</pre> |
| will change to: |
| <pre>void sort(args_proxy const &args, kwds_proxy const &kwds);</pre> |
| |
| This is because in Python 3 <code>list.sort</code> requires all its arguments be keyword arguments. |
| So you should call it like this: |
| <pre>x.sort(*tuple(), **dict(make_tuple(make_tuple("reverse", true))));</pre> |
| |
| </li> |
| <li>According to <a href="http://www.python.org/dev/peps/pep-3123/">PEP 3123</a>, |
| when building Boost.Python against Python older than 2.6, the following macros will |
| be defined in Boost.Python header: |
| <pre> |
| # define Py_TYPE(o) (((PyObject*)(o))->ob_type) |
| # define Py_REFCNT(o) (((PyObject*)(o))->ob_refcnt) |
| # define Py_SIZE(o) (((PyVarObject*)(o))->ob_size)</pre> |
| So extension writers can use these macro directly, to make code clean and compatible with Python 3. |
| </li> |
| </ul> |
| </ul> |
| </dd> |
| |
| <dt>1.39.0 Release</dt> |
| |
| <dd> |
| <ul> |
| <li>Pythonic signatures are now automatically appended to the |
| docstrings. |
| |
| <li>Use <a href="v2/docstring_options.html" |
| ><code>docstring_options.hpp</code></a> header |
| control the content of docstrings. |
| |
| <li>This new feature increases the size of the modules by about 14%. |
| If this is not acceptable it can be turned off by defining the macro |
| BOOST_PYTHON_NO_PY_SIGNATURES. Modules compiled with and without the macro |
| defined are compatible. |
| </li> |
| <li> If BOOST_PYTHON_NO_PY_SIGNATURES is undefined, this version defines the |
| macro BOOST_PYTHON_SUPPORTS_PY_SIGNATURES. This allows writing code that will compile |
| with older version of Boost.Python (see <a href="v2/pytype_function.html#examples">here</a>). |
| </li> |
| <li>By defining BOOST_PYTHON_PY_SIGNATURES_PROPER_INIT_SELF_TYPE, and at a cost |
| of another 14% size increase, proper pythonic type is generated for the "self" |
| parameter of the __init__ methods. |
| </li> |
| |
| <li> To support this new feature changes were made to the |
| <a href="v2/to_python_converter.html"><code>to_python_converter.hpp</code></a>, |
| <a href="v2/default_call_policies.html"><code>default_call_policies</code></a>, |
| <a href="v2/ResultConverter.html"><code>ResultConverter</code></a>, |
| <a href="v2/CallPolicies.html"><code>CallPolicies</code></a> and some others. |
| Efforts were made not to have interface breaking changes. |
| </li> |
| |
| </ul> |
| </dd> |
| |

| |
| <dd>Added new <code><a href="v2/str.html#str-spec">str</a></code></dd> |
| |
| <dt>constructors which take a range of characters, allowing strings |

| |
| <dt>8 Sept 2003</dt> |
| |
| <dd>Added the ability to create methods from function objects (with an |
| <code>operator()</code>); see the <a href= |

| more info.</dd> |
| |
| <dt>10 August 2003</dt> |

| >>> f(0, z = "bar") |
| >>> f(z = "bar", y = 0.0) |
| </pre>Thanks, Nikolay! |
| </dd> |
| |
| <dt>22 July 2003</dt> |
| |
| <dd>Killed the dreaded "bad argument type for builtin operation" error. |
| Argument errors now show the actual and expected argument types!</dd> |
| |
| <dt>19 July 2003</dt> |
| |
| <dd>Added the new <code><a href= |
| "v2/return_arg.html">return_arg</a></code> policy from <a href= |

| |
| <dt>18 March, 2003</dt> |
| |
| <dd><a href="mailto:Gottfried.Ganssauge-at-haufe.de">Gottfried |
| Ganßauge</a> has contributed <a href= |
| "v2/opaque.html">opaque pointer support</a>.<br> |
| <a href="mailto:nicodemus-at-globalite.com.br">Bruno da Silva de |
| Oliveira</a> has contributed the exciting <a href= |
| "../pyste/index.html">Pyste</a> ("Pie-steh") package.</dd> |
| |
| <dt>24 February 2003</dt> |
| |
| <dd>Finished improved support for <code>boost::shared_ptr</code>. Now any |
| wrapped object of C++ class <code>X</code> can be converted automatically |
| to <code>shared_ptr<X></code>, regardless of how it was wrapped. |
| The <code>shared_ptr</code> will manage the lifetime of the Python object |
| which supplied the <code>X</code>, rather than just the <code>X</code> |
| object itself, and when such a <code>shared_ptr</code> is converted back |
| to Python, the original Python object will be returned.</dd> |
| |
| <dt>19 January 2003</dt> |
| |
| <dd>Integrated <code>staticmethod</code> support from <a href= |
| "mailto:nickm-at-sitius.com">Nikolay Mladenov</a>. Thanks, Nikolay!</dd> |

| |
| <dt>20 December 2002</dt> |
| |
| <dd>Added automatic downcasting for pointers, references, and smart |
| pointers to polymorphic class types upon conversion to python</dd> |
| |
| <dt>18 December 2002</dt> |
| |
| <dd>Optimized from_python conversions for wrapped classes by putting the |
| conversion logic in the shared library instead of registering separate |
| converters for each class in each extension module</dd> |
| |
| <dt>19 November 2002</dt> |
| |
| <dd>Removed the need for users to cast base class member function |
| pointers when used as arguments to <a href= |
| "v2/class.html#class_-spec-modifiers">add_property</a></dd> |
| |
| <dt>13 December 2002</dt> |
| |
| <dd>Allow exporting of <a href= |
| "v2/enum.html#enum_-spec"><code>enum_</code></a> values into enclosing |
| <a href="v2/scope.html#scope-spec"><code>scope</code></a>.<br> |
| Fixed unsigned integer conversions to deal correctly with numbers that |
| are out-of-range of <code>signed long</code>.</dd> |
| |
| <dt>14 November 2002</dt> |
| |
| <dd>Auto-detection of class data members wrapped with <a href= |
| "v2/data_members.html#make_getter-spec"><code>make_getter</code></a></dd> |
| |
| <dt>13 November 2002</dt> |
| |
| <dd>Full Support for <code>std::auto_ptr<></code> added.</dd> |
| |
| <dt>October 2002</dt> |
| |
| <dd>Ongoing updates and improvements to tutorial documentation</dd> |
| |
| <dt>10 October 2002</dt> |
| |
| <dd>Boost.Python V2 is released!</dd> |
