Scrapy 2.11.1 (2024-02-14)

Highlights:

• Security bug fixes.

• Support for Twisted >= 23.8.0.

• Documentation improvements.

Security bug fixes

-   Addressed `ReDoS vulnerabilities`_:
-   ``scrapy.utils.iterators.xmliter`` is now deprecated in favor of
    :func:`~scrapy.utils.iterators.xmliter_lxml`, which
    :class:`~scrapy.spiders.XMLFeedSpider` now uses.
To minimize the impact of this change on existing code,
:func:`~scrapy.utils.iterators.xmliter_lxml` now supports indicating
the node namespace with a prefix in the node name, and big files with
highly nested trees when using libxml2 2.7+.


Fixed regular expressions in the implementation of the

:func:~scrapy.utils.response.open_in_browser function.

Please, see the cc65-xxvf-f7r9 security advisory_ for more information.

.. _cc65-xxvf-f7r9 security advisory: GHSA-cc65-xxvf-f7r9




:setting:DOWNLOAD_MAXSIZE and :setting:DOWNLOAD_WARNSIZE now also apply
to the decompressed response body. Please, see the 7j7m-v7m3-jqm7 security advisory_ for more information.
.. _7j7m-v7m3-jqm7 security advisory: GHSA-7j7m-v7m3-jqm7


Also in relation with the 7j7m-v7m3-jqm7 security advisory_, the
deprecated scrapy.downloadermiddlewares.decompression module has been
removed.


The Authorization header is now dropped on redirects to a different
domain. Please, see the cw9j-q3vf-hrrv security advisory_ for more
information.
