[ANN] luabind 0.9

Daniel Wallin
I'm happy to announce the release of luabind 0.9! There have been a lot
of improvements since 0.8.1. Among the more interesting ones are the
automatic handling of down casts, as well as better smart pointer
support, and of course the improved performance.

Many thanks to Athena Capital Research who funded a large part of the
development for this release.

Source packages available for download at:

  http://sourceforge.net/projects/luabind/files


User visible changes since 0.8.1
--------------------------------

 * Major optimizations. For example, calling member functions should be
   close to twice as fast.

 * Can now automatically handle conversion of any pointer like type
   that implements a get_pointer() overload.

 * Now handles virtual and multiple inheritance properly.

 * Automatically perform down-casts as well as up-casts when converting
   arguments from Lua to C++.

 * When converting from C++ to Lua, polymorphic instances are
   automatically cast to their most derived type.

 * Memory optimizations.

 * Added `table<>` object wrapper. Can be used to limit a function
   parameter to tables.

   Previously:

       void f(object const& x)
       {
           // assert that x is table
       }

   Now:

       void f(table<object> const& x)
       {
       }

 * Uses standard luaL_ref() and luaL_unref() functions. This should
   simplify integration with other libraries that make use of the
   registry.

 * Deprecated the `raw()` converter policy. lua_State* arguments are now
   automatically handled by the library.

 * Fixed common problem where objects would reference a garbage
   collected coroutine.


Breaking changes
----------------

 * Dropped support for using a custom type_info.

 * `get_const_holder()' was removed, and by extension the automatic
   smart_ptr<X> -> smart_ptr<X const>.
