 These are old release notes for Boost.Python v1

 2000-11-22 10:00
     Ullrich fixed bug in operator_dispatcher<op_long>.

 2000-11-21 10:00
     Changed all class and function names into lower_case.

     Ullrich updated documentation for operator wrapping.

 2000-11-20 10:00
     Ullrich renamed ExtensionClass:register_coerce() into
     ExtensionClass:def_standard_coerce() and made it public

     Ullrich improved shared_pod_manager.

 2000-11-17 15:04
     Changed allocation strategy of shared_pod_manager to make it portable.

     Added pickling support + tests thanks to "Ralf W. Grosse-Kunstleve"
     <rwgk@cci.lbl.gov>

     Added a specialization of Callback<const char*> to prevent unsafe usage.

     Fixed Ullrich's operator_dispatcher refcount bug

     Removed const char* return values from virtual functions in tests; that
     usage was unsafe.

     Ullrich changed Module::add() so that it steals a reference (fix of refcount bug)

     Ullrich added operator_dispatcher::create() optimization

     Ullrich changed design and implementation of TypeObjectBase::enable() (to eliminate low-level
     code) and added shared_pod_manager optimization.


 2000-11-15 12:01
     Fixed refcount bugs in operator calls.

     Added callback_adjust_refcount(PyObject*, Type<T>) to account for different ownership
     semantics of Callback's return types and Caller's arguments (which both use from_python())
     This bug caused refcount errors during operator calls.

     Moved operator_dispatcher into extclass.cpp
     Gave it shared ownership of the objects it wraps

     Introduced sequence points in extension_class_coerce for exception-safety

     UPPER_CASE_MACRO_NAMES

     MixedCase template type argument names

     Changed internal error reporting to use Python exceptions so we don't force the
     user to link in iostreams code

     Changed error return value of call_cmp to -1

     Moved unwrap_* functions out of operator_dispatcher. This was transitional: when
     I realized they didn't need to be declared in extclass.h I moved them out, but
     now that operator_dispatcher itself is in extclass.cpp they could go back in.

     Numerous formatting tweaks

     Updated the BoundFunction::create() optimization and enabled it so it could actually be used!

 2000-11-15 00:26

     Made Ullrich's operators support work with MSVC

     Cleaned up operators.h such that invalid define_operator<0> is no longer needed.

     Ullrich created operators.h to support wrapping of C++ operators (including the "__r*__" forms).
     He added several auxiliary classes to extclass.h and extclass.cpp (most importantly,
     py::detail::operator_dispatcher and py::operators)

 2000-11-13 22:29

     removed obsolete ExtensionClassFromPython for good.

     removed unused class ExtensionType forward declaration

 2000-11-12 13:08

     Added enum_as_int_converters for easier enum wrapping

     Introduced new conversion namespace macros:
         PY_BEGIN_CONVERSION_NAMESPACE,
         PY_END_CONVERSION_NAMESPACE,
         PY_CONVERSION

     callback.h, gen_callback.py:
         Added call() function so that a regular python function (as opposed to
          method or other function-as-attribute) can be called.

          Added newlines for readability.

     class_wrapper.h:
         Fixed a bug in add(), which allows non-method class attributes

     Ullrich has added def_raw for simple varargs and keyword support.

     Fixed version number check for __MWERKS__

     Added tests for enums and non-method class attributes

     objects.h/objects.cpp:
         Added py::String operator*= and operator* for repetition

         Change Dict::items(), keys(), and values() to return a List

         Added template versions of set_item, etc., methods so that users can optionally
         use C++ types that have to_python() functions as parameters.

         Changed various Ptr by-value parameters to const Ptr&


 ======= Release =======
 2000-11-06 0:22
     Lots of documentation updates

     added 4-argument template constructor to py::Tuple

     added "add" member function to ClassWrapper<> to allow arbitrary Python
     objects to be added to an extension class.

     gen_all.py now generates support for n argument member functions and n+1
     argument member functions at the suggestion of "Ralf W. Grosse-Kunstleve"
     <rwgk@cci.lbl.gov>

     Added regression tests and re-ordered declare_base calls to verify that the
     phantom base class issue is resolved.

 2000-11-04 17:35

     Integrated Ullrich Koethe's brilliant from_python_experiment for better
     error-reporting in many cases.

     extclass.h, gen_extclass.py:
         removed special-case MSVC code
         added much commentary
         removed unused py_copy_to_new_value_holder

     init_function.h, gen_init_function.py:
         added missing 'template' keyword on type-dependent template member usage
         removed special-case MSVC code
         added much commentary

 2000-11-04 0:36

     Removed the need for the phantom base class that screwed up inheritance
     hierarchies, introduced error-prone ordering dependencies, and complexified
     logic in many places!

     extclass.h: Added some explanatory comments, removed wasteful m_self member
     of HeldInstance

     extclass_demo.cpp: Added #pragmas which allow compilation in ansi strict
     mode under Metrowerks

     functions.h: Added virtual_function as part of phantom base class removal;
     expanded commentary

     pyptr.h: Added some missing 'typename's and a GCC workaround fix

     subclass.cpp: Added missing string literal const_cast<>s.

 2000-11-03 10:58

     Fix friend function instantiation bug caught by Metrowerks (thanks
     Metrowerks!)

     Add proof-of-concept for one technique of wrapping function that return a
     pointer

     Worked around MSVC optimizer bug by writing to_python(double) and
     to_python(float) out-of-line

 2000-11-02 23:25

     Add /Zm200 option to vc6_prj to deal with MSVC resource limitations

     Remove conflicting /Ot option from vc6_prj release build

 ======= Release =======
 2000-11-02 17:42

     Added a fix for interactions between default virtual function
     implementations and declare_base(). You still need to write your
     declare_base() /after/ all member functions have been def()d for the two
     classes concerned.  Many, many thanks to Ullrich Koethe
     <koethe@informatik.uni-hamburg.de> for all his work on this.

     Added missing conversions:
         to_python(float)
         from_python(const char* const&)
         from_python(const double&)
         from_python(const float&)

     Added a Regression test for a reference-counting bug thanks to Mark Evans
     (<mark.evans@clarisay.com>)

     const-ify ClassBase::getattr()

     Add repr() function to Class<T>

     Add to_python/from_python conversions for PyPtr<T>

     Standardize set_item/get_item interfaces (instead of proxies) for Dict and List

     Add Reprable<> template to newtypes.h

     Fix a bug wherein the __module__ attribute would be lost for classes that have a
     default virtual function implementation.

     Remove extra ';' in module.cpp thanks to "Ralf W. Grosse-Kunstleve"
     <rwgk@cci.lbl.gov>

     Fix a bug in the code of example1.html
