=============
Changes
-------
- Conversion system slightly changed, with the optional
conversions for :mod:`numpy` and :mod:`pandas` modified
accordingly. The changes should only matter if using
third-party conversion functions.
- The Python 3 version is now a first class citizen. `2to3`
is no longer used, and the code base is made directly
compatible with Python. This lowers significantly the
installation time with Python 3
(which matters when developping rpy2).
- The default options to initialize R (`rpy2.rinterface.initoptions') are no longer
`('rpy2', '--quiet', '--vanilla', '--no-save')` but now
`('rpy2', '--quiet', '--no-save')`.
- :class:`robjects.vectors.ListVector` can be instanciated from
any objects with a method `items()` with the expectation that the method
returns an iterable of (name, value) tuples, or even be an iterable
of (name, value) tuples.
New features
------------
- For instances of :class:`rpy2.robjects.Function`,
the `__doc__` is now a property fetching information
about the parameters in the R signature.
- Convenience function :func:`rpy2.robjects.packages.data`
to extract the datasets in an R pacakges
- :mod:`ipython`'s `rmagic` is now part of :mod:`rpy`. To use, `%load_ext
rpy2.ipython` from within IPython.
- new method :meth:`rpy2.rinterface.SexpEnvironment.keys`, returnings
the names in the environment as a tuple of Python strings.
- convenience class :class:`robjects.packages.InstalledPackages`, with a companion function
:func:`robjects.packages.isinstalled`.
- new class :class:`rinterface.SexpSymbol` to represent R symbols
Bugs fixed
----------
- :meth:`rpy2.rinterface.Sexp.do_slot` was crashing when
the parameter was an empty string (PR 155)
