~~~~~~~~~~~~~~~~
* Add the Active Record pattern for convenience. New classes :class:`Model`,
:class:`RecordList` and :class:`Record`. The :meth:`Client.model` method
now returns a single :class:`Model` instance. These models can be
reached using camel case attribute too. Example:
``client.model('res.company')`` and ``client.ResCompany`` return the same
:class:`Model`.
* Refresh the list of modules before install or upgrade.
* List all modules which have ``state not in ('uninstalled', 'uninstallable')``
when calling ``client.modules(installed=True)``.
* Add documentation.
