[dependabot]

Bumps pip from 25.1.1 to 25.3.

Changelog

Sourced from pip's changelog.

25.3 (2025-10-24)

Deprecations and Removals

• Remove support for the legacy setup.py develop editable method in setuptools editable installs; setuptools >= 64 is now required. ([#11457](https://github.com/pypa/pip/issues/11457) <https://github.com/pypa/pip/issues/11457>_)

• Remove the deprecated --global-option and --build-option. --config-setting is now the only way to pass options to the build backend. ([#11859](https://github.com/pypa/pip/issues/11859) <https://github.com/pypa/pip/issues/11859>_)

• Deprecate the PIP_CONSTRAINT environment variable for specifying build constraints.

  Use the --build-constraint option or the PIP_BUILD_CONSTRAINT environment variable instead. When build constraints are used, PIP_CONSTRAINT no longer affects isolated build environments. To enable this behavior without specifying any build constraints, use --use-feature=build-constraint. ([#13534](https://github.com/pypa/pip/issues/13534) <https://github.com/pypa/pip/issues/13534>_)

• Remove support for non-standard legacy wheel filenames. ([#13581](https://github.com/pypa/pip/issues/13581) <https://github.com/pypa/pip/issues/13581>_)

• Remove support for the deprecated setup.py bdist_wheel mechanism. Consequently, --use-pep517 is now always on, and --no-use-pep517 has been removed. ([#6334](https://github.com/pypa/pip/issues/6334) <https://github.com/pypa/pip/issues/6334>_)

Features

• When :pep:658 metadata is available, full distribution files are no longer downloaded when using pip lock or pip install --dry-run. ([#12603](https://github.com/pypa/pip/issues/12603) <https://github.com/pypa/pip/issues/12603>_)
• Add support for installing an editable requirement written as a Direct URL (PackageName @ URL). ([#13495](https://github.com/pypa/pip/issues/13495) <https://github.com/pypa/pip/issues/13495>_)
• Add support for build constraints via the --build-constraint option. This allows constraining the versions of packages used during the build process (e.g., setuptools) without affecting the final installation. ([#13534](https://github.com/pypa/pip/issues/13534) <https://github.com/pypa/pip/issues/13534>_)
• On ResolutionImpossible errors, include a note about causes with no candidates. ([#13588](https://github.com/pypa/pip/issues/13588) <https://github.com/pypa/pip/issues/13588>_)
• Building pip itself from source now uses flit-core instead of setuptools. This does not affect how pip installs or builds packages you use. ([#13473](https://github.com/pypa/pip/issues/13473) <https://github.com/pypa/pip/issues/13473>_)

Bug Fixes

• Handle malformed Version metadata entries and show a sensible error message instead of crashing. ([#13443](https://github.com/pypa/pip/issues/13443) <https://github.com/pypa/pip/issues/13443>_)
• Permit spaces between a filepath and extras in an install requirement. ([#13523](https://github.com/pypa/pip/issues/13523) <https://github.com/pypa/pip/issues/13523>_)
• Ensure the self-check files in the cache have the same permissions as the rest of the cache. ([#13528](https://github.com/pypa/pip/issues/13528) <https://github.com/pypa/pip/issues/13528>_)
• Avoid concurrency issues and improve performance when caching locally built wheels, especially when the temporary build directory is on a different filesystem than the cache. The wheel directory passed to the build backend is now a temporary subdirectory inside the cache directory. ([#13540](https://github.com/pypa/pip/issues/13540) <https://github.com/pypa/pip/issues/13540>_)
• Include relevant user-supplied constraints in logs when reporting dependency conflicts. ([#13545](https://github.com/pypa/pip/issues/13545) <https://github.com/pypa/pip/issues/13545>_)
• Fix a regression in configuration parsing that was turning a single value into a list and thus leading to a validation error. ([#13548](https://github.com/pypa/pip/issues/13548) <https://github.com/pypa/pip/issues/13548>_)
• For Python versions that do not support :pep:706, pip will now raise an installation error for a source distribution when it includes a symlink that points outside the source distribution archive. ([#13550](https://github.com/pypa/pip/issues/13550) <https://github.com/pypa/pip/issues/13550>_)
• Prevent --user installs if site.ENABLE_USER_SITE is set to False. ([#8794](https://github.com/pypa/pip/issues/8794) <https://github.com/pypa/pip/issues/8794>_)
