Changelog

Sourced from pip's changelog.

23.3 (2023-10-15)

Process

• Added reference to vulnerability reporting guidelines <https://www.python.org/dev/security/>_ to pip's security policy.

Deprecations and Removals

• Drop a fallback to using SecureTransport on macOS. It was useful when pip detected OpenSSL older than 1.0.1, but the current pip does not support any Python version supporting such old OpenSSL versions. ([#12175](https://github.com/pypa/pip/issues/12175) <https://github.com/pypa/pip/issues/12175>_)

Features

• Improve extras resolution for multiple constraints on same base package. ([#11924](https://github.com/pypa/pip/issues/11924) <https://github.com/pypa/pip/issues/11924>_)
• Improve use of datastructures to make candidate selection 1.6x faster. ([#12204](https://github.com/pypa/pip/issues/12204) <https://github.com/pypa/pip/issues/12204>_)
• Allow pip install --dry-run to use platform and ABI overriding options. ([#12215](https://github.com/pypa/pip/issues/12215) <https://github.com/pypa/pip/issues/12215>_)
• Add is_yanked boolean entry to the installation report (--report) to indicate whether the requirement was yanked from the index, but was still selected by pip conform to :pep:592. ([#12224](https://github.com/pypa/pip/issues/12224) <https://github.com/pypa/pip/issues/12224>_)

Bug Fixes

• Ignore errors in temporary directory cleanup (show a warning instead). ([#11394](https://github.com/pypa/pip/issues/11394) <https://github.com/pypa/pip/issues/11394>_)
• Normalize extras according to :pep:685 from package metadata in the resolver for comparison. This ensures extras are correctly compared and merged as long as the package providing the extra(s) is built with values normalized according to the standard. Note, however, that this does not solve cases where the package itself contains unnormalized extra values in the metadata. ([#11649](https://github.com/pypa/pip/issues/11649) <https://github.com/pypa/pip/issues/11649>_)
• Prevent downloading sdists twice when :pep:658 metadata is present. ([#11847](https://github.com/pypa/pip/issues/11847) <https://github.com/pypa/pip/issues/11847>_)
• Include all requested extras in the install report (--report). ([#11924](https://github.com/pypa/pip/issues/11924) <https://github.com/pypa/pip/issues/11924>_)
• Removed uses of datetime.datetime.utcnow from non-vendored code. ([#12005](https://github.com/pypa/pip/issues/12005) <https://github.com/pypa/pip/issues/12005>_)
• Consistently report whether a dependency comes from an extra. ([#12095](https://github.com/pypa/pip/issues/12095) <https://github.com/pypa/pip/issues/12095>_)
• Fix completion script for zsh ([#12166](https://github.com/pypa/pip/issues/12166) <https://github.com/pypa/pip/issues/12166>_)
• Fix improper handling of the new onexc argument of shutil.rmtree() in Python 3.12. ([#12187](https://github.com/pypa/pip/issues/12187) <https://github.com/pypa/pip/issues/12187>_)
• Filter out yanked links from the available versions error message: "(from versions: 1.0, 2.0, 3.0)" will not contain yanked versions conform PEP 592. The yanked versions (if any) will be mentioned in a separate error message. ([#12225](https://github.com/pypa/pip/issues/12225) <https://github.com/pypa/pip/issues/12225>_)
• Fix crash when the git version number contains something else than digits and dots. ([#12280](https://github.com/pypa/pip/issues/12280) <https://github.com/pypa/pip/issues/12280>_)
• Use -r=... instead of -r ... to specify references with Mercurial. ([#12306](https://github.com/pypa/pip/issues/12306) <https://github.com/pypa/pip/issues/12306>_)
• Redact password from URLs in some additional places. ([#12350](https://github.com/pypa/pip/issues/12350) <https://github.com/pypa/pip/issues/12350>_)
• pip uses less memory when caching large packages. As a result, there is a new on-disk cache format stored in a new directory ($PIP_CACHE_DIR/http-v2). ([#2984](https://github.com/pypa/pip/issues/2984) <https://github.com/pypa/pip/issues/2984>_)

Updates gunicorn from 19.9.0 to 22.0.0

Release notes

Sourced from gunicorn's releases.

Gunicorn 22.0 has been released

Gunicorn 22.0.0 has been released. This version fix the numerous security vulnerabilities. You're invited to upgrade asap your own installation.

Changes:

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

1. Documentation is available there: https://docs.gunicorn.org/en/stable/news.html
2. Packages: https://pypi.org/project/gunicorn/
