| ================ | ||
| Changelog - 2024 | ||
| ================ | ||
|
|
||
| 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. | ||
|
|
||
| 22.0.0 - 2024-04-17 | ||
| =================== | ||
|
|
||
| - use `utime` to notify workers liveness | ||
| - migrate setup to pyproject.toml | ||
| - fix numerous security vulnerabilities in HTTP parser (closing some request smuggling vectors) | ||
| - parsing additional requests is no longer attempted past unsupported request framing | ||
| - on HTTP versions < 1.1 support for chunked transfer is refused (only used in exploits) | ||
| - requests conflicting configured or passed SCRIPT_NAME now produce a verbose error | ||
| - Trailer fields are no longer inspected for headers indicating secure scheme | ||
| - support Python 3.12 | ||
|
|
||
| ** Breaking changes ** | ||
|
|
||
| - minimum version is Python 3.7 | ||
| - the limitations on valid characters in the HTTP method have been bounded to Internet Standards | ||
| - requests specifying unsupported transfer coding (order) are refused by default (rare) | ||
| - HTTP methods are no longer casefolded by default (IANA method registry contains none affected) | ||
| - HTTP methods containing the number sign (#) are no longer accepted by default (rare) | ||
| - HTTP versions < 1.0 or >= 2.0 are no longer accepted by default (rare, only HTTP/1.1 is supported) | ||
| - HTTP versions consisting of multiple digits or containing a prefix/suffix are no longer accepted | ||
| - HTTP header field names Gunicorn cannot safely map to variables are silently dropped, as in other software | ||
| - HTTP headers with empty field name are refused by default (no legitimate use cases, used in exploits) | ||
| - requests with both Transfer-Encoding and Content-Length are refused by default (such a message might indicate an attempt to perform request smuggling) | ||
| - empty transfer codings are no longer permitted (reportedly seen with really old & broken proxies) | ||
|
|
||
|
|
||
| ** SECURITY ** | ||
|
|
||
| - fix CVE-2024-1135 |
