scrapy/scrapy 2.6.0 on GitHub

Security fixes for cookie handling (see details below)
Python 3.10 support
asyncio support is no longer considered experimental, and works out-of-the-box on Windows regardless of your Python version
Feed exports now support pathlib.Path output paths and per-feed item filtering and post-processing

When a Request object with cookies defined gets a redirect response causing a new Request object to be scheduled, the cookies defined in the original Request object are no longer copied into the new Request object.
If you manually set the Cookie header on a Request object and the domain name of the redirect URL is not an exact match for the domain of the URL of the original Request object, your Cookie header is now dropped from the new Request object.
The old behavior could be exploited by an attacker to gain access to your cookies. Please, see the cjvr-mfj7-j4j8 security advisory for more
information.
Note: It is still possible to enable the sharing of cookies between different domains with a shared domain suffix (e.g. example.com and any subdomain) by defining the shared domain suffix (e.g. example.com) as the cookie domain when defining your cookies. See the documentation of the Request class for more information.
When the domain of a cookie, either received in the Set-Cookie header of a response or defined in a Request object, is set to a public suffix <https://publicsuffix.org/>_, the cookie is now ignored unless the cookie domain is the same as the request domain.
The old behavior could be exploited by an attacker to inject cookies from a controlled domain into your cookiejar that could be sent to other domains not controlled by the attacker. Please, see the mfjm-vh54-3f96 security advisory for more information.
