23.1 (2023-04-15)

Deprecations and Removals

• Remove support for the deprecated --install-options. ([#11358](https://github.com/pypa/pip/issues/11358) <https://github.com/pypa/pip/issues/11358>_)
• --no-binary does not imply setup.py install anymore. Instead a wheel will be built locally and installed. ([#11451](https://github.com/pypa/pip/issues/11451) <https://github.com/pypa/pip/issues/11451>_)
• --no-binary does not disable the cache of locally built wheels anymore. It only means "don't download wheels". ([#11453](https://github.com/pypa/pip/issues/11453) <https://github.com/pypa/pip/issues/11453>_)
• Deprecate --build-option and --global-option. Users are invited to switch to --config-settings. ([#11859](https://github.com/pypa/pip/issues/11859) <https://github.com/pypa/pip/issues/11859>_)
• Using --config-settings with projects that don't have a pyproject.toml now print a deprecation warning. In the future the presence of config settings will automatically enable the default build backend for legacy projects and pass the setttings to it. ([#11915](https://github.com/pypa/pip/issues/11915) <https://github.com/pypa/pip/issues/11915>_)
• Remove setup.py install fallback when building a wheel failed for projects without pyproject.toml. ([#8368](https://github.com/pypa/pip/issues/8368) <https://github.com/pypa/pip/issues/8368>_)
• When the wheel package is not installed, pip now uses the default build backend instead of setup.py install for project without pyproject.toml. ([#8559](https://github.com/pypa/pip/issues/8559) <https://github.com/pypa/pip/issues/8559>_)

Features

• Specify egg-link location in assertion message when it does not match installed location to provide better error message for debugging. ([#10476](https://github.com/pypa/pip/issues/10476) <https://github.com/pypa/pip/issues/10476>_)
• Present conflict information during installation after each choice that is rejected (pass -vv to pip install to show it) ([#10937](https://github.com/pypa/pip/issues/10937) <https://github.com/pypa/pip/issues/10937>_)
• Display dependency chain on each Collecting/Processing log line. ([#11169](https://github.com/pypa/pip/issues/11169) <https://github.com/pypa/pip/issues/11169>_)
• Support a per-requirement --config-settings option in requirements files. ([#11325](https://github.com/pypa/pip/issues/11325) <https://github.com/pypa/pip/issues/11325>_)
• The --config-settings/-C option now supports using the same key multiple times. When the same key is specified multiple times, all values are passed to the build backend as a list, as opposed to the previous behavior, where pip would only pass the last value if the same key was used multiple times. ([#11681](https://github.com/pypa/pip/issues/11681) <https://github.com/pypa/pip/issues/11681>_)
• Add -C as a short version of the --config-settings option. ([#11786](https://github.com/pypa/pip/issues/11786) <https://github.com/pypa/pip/issues/11786>_)
• Reduce the number of resolver rounds, since backjumping makes the resolver more efficient in finding solutions. This also makes pathological cases fail quicker. ([#11908](https://github.com/pypa/pip/issues/11908) <https://github.com/pypa/pip/issues/11908>_)
• Warn if --hash is used on a line without requirement in a requirements file. ([#11935](https://github.com/pypa/pip/issues/11935) <https://github.com/pypa/pip/issues/11935>_)
• Stop propagating CLI --config-settings to the build dependencies. They already did not propagate to requirements provided in requirement files. To pass the same config settings to several requirements, users should provide the requirements as CLI arguments. ([#11941](https://github.com/pypa/pip/issues/11941) <https://github.com/pypa/pip/issues/11941>_)
• Support wheel cache when using --require-hashes. ([#5037](https://github.com/pypa/pip/issues/5037) <https://github.com/pypa/pip/issues/5037>_)
• Add --keyring-provider flag. See the Authentication page in the documentation for more info. ([#8719](https://github.com/pypa/pip/issues/8719) <https://github.com/pypa/pip/issues/8719>_)
• In the case of virtual environments, configuration files are now also included from the base installation. ([#9752](https://github.com/pypa/pip/issues/9752) <https://github.com/pypa/pip/issues/9752>_)

Bug Fixes

• Fix grammar by changing "A new release of pip available:" to "A new release of pip is available:" in the notice used for indicating that. ([#11529](https://github.com/pypa/pip/issues/11529) <https://github.com/pypa/pip/issues/11529>_)
• Normalize paths before checking if installed scripts are on PATH. ([#11719](https://github.com/pypa/pip/issues/11719) <https://github.com/pypa/pip/issues/11719>_)
• Correct the way to decide if keyring is available. ([#11774](https://github.com/pypa/pip/issues/11774) <https://github.com/pypa/pip/issues/11774>_)
• More consistent resolution backtracking by removing legacy hack related to setuptools resolution ([#11837](https://github.com/pypa/pip/issues/11837) <https://github.com/pypa/pip/issues/11837>_)
