CONCURRENT_REQUESTS_PER_DOMAIN (from 8 to 1) in the default project
template.
* Fixed several bugs in the engine initialization and exception handling
logic.

values are the same.
* The asyncio reactor is now enabled by default
* Replaced start_requests() (sync) with start() (async) and changed how it
is iterated.
* Added the allow_offsite request meta key
* Spider middlewares that don't support asynchronous spider output are
deprecated
* Added a base class for universal spider middlewares
- Add patch remove-hoverxref.patch:

* Redirects to non-HTTP protocols are no longer followed.
Please, see the 23j4-mw76-5v7h security advisory for more
information. (:issue:`457`)
* The Authorization header is now dropped on redirects to a
different scheme (http:// or https://) or port, even if the
domain is the same. Please, see the 4qqq-9vqf-3h3f security
advisory for more information.
* When using system proxy settings that are different for
http:// and https://, redirects to a different URL scheme
will now also trigger the corresponding change in proxy
settings for the redirected request. Please, see the
jm3v-qxmh-hxwv security advisory for more information.
(:issue:`767`)
* :attr:`Spider.allowed_domains
<scrapy.Spider.allowed_domains>` is now enforced for all
requests, and not only requests from spider callbacks.
* :func:`~scrapy.utils.iterators.xmliter_lxml` no longer
resolves XML entities.
* defusedxml is now used to make
:class:`scrapy.http.request.rpc.XmlRpcRequest` more secure.
* Restored support for brotlipy_, which had been dropped in
Scrapy 2.11.1 in favor of brotli. (:issue:`6261`) Note
brotlipy is deprecated, both in Scrapy and upstream. Use
brotli instead if you can.
* Make :setting:`METAREFRESH_IGNORE_TAGS` ["noscript"] by
default. This prevents :class:`~scrapy.downloadermiddlewares.
redirect.MetaRefreshMiddleware` from following redirects that
would not be followed by web browsers with JavaScript
enabled.

* 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.

- Update to v2.6.2
Security bug fix:
* When HttpProxyMiddleware processes a request with proxy metadata, and that proxy metadata includes proxy credentials,
HttpProxyMiddleware sets the Proxy-Authentication header, but only if that header is not already set.
* There are third-party proxy-rotation downloader middlewares that set different proxy metadata every time they process a request.
* Because of request retries and redirects, the same request can be processed by downloader middlewares more than once,
including both HttpProxyMiddleware and any third-party proxy-rotation downloader middleware.
* These third-party proxy-rotation downloader middlewares could change the proxy metadata of a request to a new value,
but fail to remove the Proxy-Authentication header from the previous value of the proxy metadata, causing the credentials of one
proxy to be sent to a different proxy.
* To prevent the unintended leaking of proxy credentials, the behavior of HttpProxyMiddleware is now as follows when processing a request:
+ If the request being processed defines proxy metadata that includes credentials, the Proxy-Authorization header is always updated
to feature those credentials.
+ If the request being processed defines proxy metadata without credentials, the Proxy-Authorization header is removed unless
it was originally defined for the same proxy URL.
+ To remove proxy credentials while keeping the same proxy URL, remove the Proxy-Authorization header.
+ If the request has no proxy metadata, or that metadata is a falsy value (e.g. None), the Proxy-Authorization header is removed.
+ It is no longer possible to set a proxy URL through the proxy metadata but set the credentials through the Proxy-Authorization header.
Set proxy credentials through the proxy metadata instead.
* Also fixes the following regressions introduced in 2.6.0:
+ CrawlerProcess supports again crawling multiple spiders (issue 5435, issue 5436)
+ Installing a Twisted reactor before Scrapy does (e.g. importing twisted.internet.reactor somewhere at the module level)
no longer prevents Scrapy from starting, as long as a different reactor is not specified in TWISTED_REACTOR (issue 5525, issue 5528)
+ Fixed an exception that was being logged after the spider finished under certain conditions (issue 5437, issue 5440)
+ The --output/-o command-line parameter supports again a value starting with a hyphen (issue 5444, issue 5445)
+ The scrapy parse -h command no longer throws an error (issue 5481, issue 5482)

- Update to 2.5.1, Security bug fix
* boo#1191446, CVE-2021-41125
* If you use HttpAuthMiddleware (i.e. the http_user and
http_pass spider attributes) for HTTP authentication,
any request exposes your credentials to the request
target.
* To prevent unintended exposure of authentication
credentials to unintended domains, you must now
additionally set a new, additional spider attribute,
http_auth_domain, and point it to the specific domain to
which the authentication credentials must be sent.
* If the http_auth_domain spider attribute is not set, the
domain of the first request will be considered the HTTP
authentication target, and authentication credentials
will only be sent in requests targeting that domain.
* If you need to send the same HTTP authentication
credentials to multiple domains, you can use
w3lib.http.basic_auth_header instead to set the value of
the Authorization header of your requests.
* If you really want your spider to send the same HTTP
authentication credentials to any domain, set the
http_auth_domain spider attribute to None.
* Finally, if you are a user of scrapy-splash, know that
this version of Scrapy breaks compatibility with
scrapy-splash 0.7.2 and earlier. You will need to upgrade
scrapy-splash to a greater version for it to continue to
work.

- Update to 2.5.0:
* Official Python 3.9 support
* Experimental HTTP/2 support
* New get_retry_request() function to retry requests from spider
callbacks
* New headers_received signal that allows stopping downloads
early
* New Response.protocol attribute
- Release 2.4.1:
* Fixed feed exports overwrite support
* Fixed the asyncio event loop handling, which could make code
hang
* Fixed the IPv6-capable DNS resolver CachingHostnameResolver
for download handlers that call reactor.resolve
* Fixed the output of the genspider command showing placeholders
instead of the import part of the generated spider module
(issue 4874)
- Release 2.4.0:
* Python 3.5 support has been dropped.
* The file_path method of media pipelines can now access the
source item.
* This allows you to set a download file path based on item data.
* The new item_export_kwargs key of the FEEDS setting allows to
define keyword parameters to pass to item exporter classes.
* You can now choose whether feed exports overwrite or append to
the output file.
* For example, when using the crawl or runspider commands, you
can use the -O option instead of -o to overwrite the output
file.
* Zstd-compressed responses are now supported if zstandard is
installed.
* In settings, where the import path of a class is required, it
is now possible to pass a class object instead.
- Release 2.3.0:
* Feed exports now support Google Cloud Storage as a storage
backend
* The new FEED_EXPORT_BATCH_ITEM_COUNT setting allows to deliver
output items in batches of up to the specified number of items.
* It also serves as a workaround for delayed file delivery,
which causes Scrapy to only start item delivery after the
crawl has finished when using certain storage backends (S3,
FTP, and now GCS).
* The base implementation of item loaders has been moved into a
separate library, itemloaders, allowing usage from outside
Scrapy and a separate release schedule
- Release 2.2.1:
* The startproject command no longer makes unintended changes to
the permissions of files in the destination folder, such as
removing execution permissions.
