Release notes
=============
@ -6,6 +8,7 @@ Release notes
Scrapy changes:
- added :ref:`topics-contracts`, a mechanism for testing spiders in a formal/reproducible way
- added options ``-o`` and ``-t`` to the :command:`runspider` command
- documented :doc:`topics/autothrottle` and added to extensions installed by default. You still need to enable it with :setting:`AUTOTHROTTLE_ENABLED`
- major Stats Collection refactoring: removed separation of global/per-spider stats, removed stats-related signals (``stats_spider_opened``, etc). Stats are much simpler now, backwards compatibility is kept on the Stats Collector API and signals.

Spiders Contracts
=================
.. versionadded:: 0.15
.. note:: This is a new feature (introduced in Scrapy 0.15) and may be subject
to minor functionality/API updates. Check the :ref:`release notes <news>` to
be notified of updates.
Testing spiders can get particularly annoying and while nothing prevents you
from writing unit tests the task gets cumbersome quickly. Scrapy offers an
integrated way of testing your spiders by the means of contracts.
