23.0.0

Gunicorn 23.0.0 has been released. This version improve HTTP 1.1. support and which improve safety

You're invited to upgrade asap your own installation.

23.0.0 - 2024-08-10

• minor docs fixes (:pr:3217, :pr:3089, :pr:3167)
• worker_class parameter accepts a class (:pr:3079)
• fix deadlock if request terminated during chunked parsing (:pr:2688)
• permit receiving Transfer-Encodings: compress, deflate, gzip (:pr:3261)
• permit Transfer-Encoding headers specifying multiple encodings. note: no parameters, still (:pr:3261)
• sdist generation now explicitly excludes sphinx build folder (:pr:3257)
• decode bytes-typed status (as can be passed by gevent) as utf-8 instead of raising TypeError (:pr:2336)
• raise correct Exception when encounting invalid chunked requests (:pr:3258)
• the SCRIPT_NAME and PATH_INFO headers, when received from allowed forwarders, are no longer restricted for containing an underscore (:pr:3192)
• include IPv6 loopback address [::1] in default for :ref:forwarded-allow-ips and :ref:proxy-allow-ips (:pr:3192)

** NOTE **

• The SCRIPT_NAME change mitigates a regression that appeared first in the 22.0.0 release
• Review your :ref:forwarded-allow-ips setting if you are still not seeing the SCRIPT_NAME transmitted
• Review your :ref:forwarder-headers setting if you are missing headers after upgrading from a version prior to 22.0.0

** Breaking changes **

• refuse requests where the uri field is empty (:pr:3255)
• refuse requests with invalid CR/LR/NUL in heade field values (:pr:3253)
• remove temporary --tolerate-dangerous-framing switch from 22.0 (:pr:3260)
• If any of the breaking changes affect you, be aware that now refused requests can post a security problem, especially so in setups involving request pipe-lining and/or proxies.
