Bugs fixed ----------
- Extracting configuration information from should now work when R is emitting a warning (issue 247)
- On OS X the library discovery step can yield nothing (see issue 246). A tentative fix is to issue a warning and keep moving.

=============
Bugs fixed ----------
- Require singledispatch if Python 3.3 (issue 232)
- Fixed bug when R spits out a warning when asked configuration information (issue 233)
- Restored printing of compilation information when running `setup.py`
- Fixed installation issue on some systems (issue 234)
- Workaround obscure failure message from unittest if Python < 3.4 and :mod:`singledispatch` cannot be imported (issue 235)
2.5.0
=============
New features ------------
- Experimental alternative way to preserve R objects from garbage collection. This can be activated with `rinterface.initr(r_preservehash=True)` (default is `False`.
- :class:`GGPlot` object getting a method :meth:`save` mirroring R's `ggplot2::ggsave()`.
- The conversion system is now using generics/single dispatch.
- New module :mod:`rpy2.ipython.html` with HTML display for rpy2 objects
- [Experimental] New function :func:`robjects.methods.rs4instance_factory` to type RS4 objects with more specificity.
Changes -------
- The script `setup.py` was rewritten for clarity and ease of maintenance. Now it only uses `setuptools`.
