* Addressed `ReDoS vulnerabilities` (bsc#1220514, CVE-2024-1892)
- ``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.
