Release 1.112.0
---------------
New features
............
1. On Windows, you can now request that the MPS allocate address space
from the top down, allowing a 32-bit executable linked with
``/LARGEADDRESSAWARE`` to use the top half of the address space.
Use the keyword argument :c:macro:`MPS_KEY_VMW3_TOP_DOWN` when
creating an arena of class :c:func:`mps_arena_class_vm`.
2. On OS X, multi-threaded programs are now supported. See
:ref:`topic-thread`.
3. On OS X, you can now debug the MPS using ``lldb``.
Interface changes
.................
1. In the :term:`hot` (production) variety, the default assertion handler
now prints messages to standard error but does *not* terminate the
program. Even though assertions indicate serious problems in the
program, an end-user does not want an application to terminate when
program, an end-user does not always want an application to terminate when
there is a chance to shut down safely and save work, or even to limp
along indefinitely. See :ref:`topic-error-assertion-handling`.

6. On OS X, signals are no longer used for handling memory protection
exceptions. This means that programs are free to handle ``SIGBUS``,
but must not install a thread-local Mach exception handler for
``EXC_BAD_ACCESS`` exceptions. See :ref:`topic-thread-signal`.
7. On OS X, when debugging with ``gdb``, you no longer need to turn on
``dont-handle-bad-access`` or to request special handling of
``SIGBUS``.
