:class:`~scrapy.http.Request` objects instead of arbitrary Python data
structures.
* An additional ``crawler`` parameter has been added to the ``__init__`` method
of the :class:`scrapy.core.scheduler.Scheduler` class.
Custom scheduler subclasses which don't accept arbitrary parameters in
their ``__init__`` method might break because of this change.
For more information, refer to the documentation for the :setting:`SCHEDULER` setting.
