[dependabot]

Updates pip from 26.1.2 to 26.2

Changelog

Sourced from pip's changelog.

26.2 (2026-07-29)

Deprecations and Removals

• Newly published packages will no longer be immediately visible to pip if the index uses caching. To install a newly published package, use --refresh-package. ([#13680](https://github.com/pypa/pip/issues/13680) <https://github.com/pypa/pip/issues/13680>_)

• Drop support for detecting legacy, non-:pep:405, virtualenv (< 20) environments. ([#14062](https://github.com/pypa/pip/issues/14062) <https://github.com/pypa/pip/issues/14062>_)

• Constraints files, including PIP_CONSTRAINT, no longer affect isolated build environments. Use --build-constraint or the PIP_BUILD_CONSTRAINT environment variable to constrain build dependencies instead.

  The --use-feature=build-constraint flag is now always enabled and has no effect. ([#14094](https://github.com/pypa/pip/issues/14094) <https://github.com/pypa/pip/issues/14094>_)

Features

• Declare support for Python 3.15 ([#14208](https://github.com/pypa/pip/issues/14208) <https://github.com/pypa/pip/issues/14208>_)

• Support self-referential extras officially. pip has supported this by accident since version 21.2. ([#11296](https://github.com/pypa/pip/issues/11296) <https://github.com/pypa/pip/issues/11296>_)

• Add --only-deps flag to instruct pip to select only the dependencies of supplied packages. It cannot be used with --no-deps, -r, --group, or --requirements-from-script. ([#11440](https://github.com/pypa/pip/issues/11440) <https://github.com/pypa/pip/issues/11440>_)

• Cache simple responses in accordance to their Cache-Control header instead of always revalidating on every request. To refresh cached package index responses and ensure newly published packages are found, use --refresh-package <package>. ([#13680](https://github.com/pypa/pip/issues/13680) <https://github.com/pypa/pip/issues/13680>_)

• Add --no-require-hashes to disable automatic enablement of --require-hashes when encountering a requirement with hashes. ([#14169](https://github.com/pypa/pip/issues/14169) <https://github.com/pypa/pip/issues/14169>_)

• Honor --only-final when sourcing requirements with -r pylock.toml. ([#13950](https://github.com/pypa/pip/issues/13950) <https://github.com/pypa/pip/issues/13950>_)

• Add support for pylock.toml upload-time field, so --uploaded-prior-to works with -r pylock.toml. ([#14168](https://github.com/pypa/pip/issues/14168) <https://github.com/pypa/pip/issues/14168>_)

• Better error messages in case of conflicts with requirements from -r pylock.toml. ([#13963](https://github.com/pypa/pip/issues/13963) <https://github.com/pypa/pip/issues/13963>_)

• Add experimental support for isolating build subprocesses by creating standard virtual environments. This will fix most (if not all) subtle isolation issues that can lead to broken builds exclusive to pip. The feature can be enabled via --use-feature=venv-isolation and will be enabled by default in a future release.

  Note that the feature has limited compatibility with --use-feature=inprocess-build-deps. While most builds should work with both features enabled, there are known edge cases. inprocess-build-deps will not be enabled by default until they are fixed. ([#14070](https://github.com/pypa/pip/issues/14070) <https://github.com/pypa/pip/issues/14070>_)

• Present more informative diagnostic errors on uncaught network errors. ([#14115](https://github.com/pypa/pip/issues/14115) <https://github.com/pypa/pip/issues/14115>_)

• Allow opting out of Git partial clones with PIP_NO_PARTIAL_CLONE_FOR_BROKEN_GIT_SERVER. ([#11043](https://github.com/pypa/pip/issues/11043) <https://github.com/pypa/pip/issues/11043>_)

• Add a --no-proxy-env (or --proxy "") option to ignore proxies configured via non-pip environment variables or configuration files. A proxy set with --proxy is still used. ([#5378](https://github.com/pypa/pip/issues/5378) <https://github.com/pypa/pip/issues/5378>_)

• Add support for pulling username from keyring subprocess provider ([#12543](https://github.com/pypa/pip/issues/12543) <https://github.com/pypa/pip/issues/12543>_)

• Speedup tab autocompletion by lazy-importing certain modules. ([#4768](https://github.com/pypa/pip/issues/4768) <https://github.com/pypa/pip/issues/4768>_)

Updates setuptools from 82.0.1 to 83.0.0

Changelog

Sourced from setuptools's changelog.

v83.0.0

Features

• Require Python 3.10 or later.

Bugfixes

• MANIFEST.in matching (via FileList) is now insensitive to Unicode normalization form. A pattern authored in one form (e.g. NFC, as typically saved by editors) now matches a file whose name is stored on disk in another (e.g. NFD, as produced by macOS APFS/HFS+). Previously an exclude, global-exclude, recursive-exclude, or prune rule could silently fail to drop a non-ASCII-named file from the source distribution, publishing it despite the exclusion -- see GHSA-h35f-9h28-mq5c.
