Debug build uses the same ABI as release build
-----------------------------------------------

Python now uses the same ABI when built in release and in debug mode. On Unix,
when Python is build in debug mode, it is now possible to load C extensions
built in release mode and C extensions built using the stable ABI.

Release build and debug build are now ABI compatible: the ``Py_DEBUG`` define
no longer implies the ``Py_TRACE_REFS`` define which introduces the only ABI
incompatibility. A new ``./configure --with-trace-refs`` build option is now
required to get ``Py_TRACE_REFS`` define which adds :func:`sys.getobjects`
function and :envvar:`PYTHONDUMPREFS` environment variable.

Release builds and debug builds are now ABI compatible: defining the

adds the :func:`sys.getobjects` function and the :envvar:`PYTHONDUMPREFS`
environment variable, can be set using the new ``./configure --with-trace-refs``
build option.

On Unix, C extensions are no longer linked to libpython. It is now possible to
load a C extension built using a shared library Python

It is now possible for a statically linked Python to load a C extension built

When Python is embedded, ``libpython`` must not be loaded with ``RTLD_LOCAL``,
but ``RTLD_GLOBAL`` instead. Previously, using ``RTLD_LOCAL``, it was already

IMPORTANT: if you want to build a debug-enabled Python, it is recommended that
you use ``./configure --with-pydebug``, rather than the options listed here.
