* Updated connector with simple connection pool
* New ``POOL_SIZE`` config attribute
* :class:`BaseSearchConfig` in the ``sphinxit.core.helpers`` module

* :class:`Q` object was renamed to :class:`OR` object, more meaningful name
* Explicit config class with ``DEBUG``, ``WITH_META``, ``WITH_STATUS`` and ``SEARCHD_CONNECTION`` attributes

* ``OPTION`` clause is implemented
* Implicit arguments types corrections, if possible
* :class:``RawAttr`` object if you need more flexible queries
* Much more tests

--------------------------

* Python 3 compatibility (thanks to ``six`` layer)
* ``oursql`` as MySQL layer (no more ``MySQLdb``)
* Fixes in meta characters escaping
* The code is more polished and tested

--------------------------
