----------------
- Highlight objects with a ``__del__`` method.
- Fixes `LP483411 <https://launchpad.net/bugs/483411>`_: suggest always passing
``[obj]`` to :func:`show_refs`, :func:`show_backrefs`, since obj might be a
list/tuple.
- Fixes `LP514422 <https://launchpad.net/bugs/514422>`_: :func:`show_refs`,
:func:`show_backrefs` don't create files in the current working directory any
more. Instead they accept a filename argument, which can be a .dot file or a
.png file. If None or not specified, those functions will try to spawn xdot
as before.
- New extra_info argument to graph-generating functions (patch by Thouis Jones,
`LP558914 <https://launchpad.net/bugs/558914>`_).
- setup.py should work with distutils now (`LP604430
<https://launchpad.net/bugs/604430>`_, thanks to Randy Heydon).
