- Waitress now validates that chunked encoding extensions are valid, and don't
contain invalid characters that are not allowed. They are still skipped/not
processed, but if they contain invalid data we no longer continue in and
return a 400 Bad Request. This stops potential HTTP desync/HTTP request
smuggling. Thanks to Zhang Zeyu for reporting this issue. See
https://github.com/Pylons/waitress/security/advisories/GHSA-4f7p-27jc-3c36
Waitress now validates that the chunk length is only valid hex digits when
parsing chunked encoding, and values such as 0x01 and +01 are no
longer supported. This stops potential HTTP desync/HTTP request smuggling.

Waitress now validates that the Content-Length sent by a remote contains only
digits in accordance with RFC7230 and will return a 400 Bad Request when the
Content-Length header contains invalid data, such as +10 which would
previously get parsed as 10 and accepted. This stops potential HTTP
desync/HTTP request smuggling Thanks to Zhang Zeyu for reporting this issue. See

2.1.0
Python Version Support
Python 3.6 is no longer supported by Waitress
Python 3.10 is fully supported by Waitress
Bugfix
- ``wsgi.file_wrapper`` now sets the ``seekable``, ``seek``, and ``tell``
attributes from the underlying file if the underlying file is seekable. This
allows WSGI middleware to implement things like range requests for example
In Python 3 OSError is no longer subscriptable, this caused failures on
Windows attempting to loop to find an socket that would work for use in the
trigger.
