Disable PEP 658 metadata fetching with the legacy resolver. ([#12156](https://github.com/pypa/pip/issues/12156) <https://github.com/pypa/pip/issues/12156>_)
23.2 (2023-07-15)
Process
Deprecate support for eggs for Python 3.11 or later, when the new importlib.metadata backend is used to load distribution metadata. This only affects the egg distribution format (with the .egg extension); distributions using the .egg-infometadata format (but are not actually eggs) are not affected. For more information about eggs, see relevant section in the setuptools documentation <https://setuptools.pypa.io/en/stable/deprecated/python_eggs.html>__.
Deprecations and Removals
Deprecate legacy version and version specifiers that don't conform to PEP 440 <https://peps.python.org/pep-0440/>_ ([#12063](https://github.com/pypa/pip/issues/12063) <https://github.com/pypa/pip/issues/12063>_)
freeze no longer excludes the setuptools, distribute, and wheel
from the output when running on Python 3.12 or later, where they are not
included in a virtual environment by default. Use --exclude if you wish to
exclude any of these packages. ([#4256](https://github.com/pypa/pip/issues/4256) <https://github.com/pypa/pip/issues/4256>_)
Features
make rejection messages slightly different between 1 and 8, so the user can make the difference. ([#12040](https://github.com/pypa/pip/issues/12040) <https://github.com/pypa/pip/issues/12040>_)
Prevent downloading files twice when PEP 658 metadata is present ([#11847](https://github.com/pypa/pip/issues/11847) <https://github.com/pypa/pip/issues/11847>_)
Add permission check before configuration ([#11920](https://github.com/pypa/pip/issues/11920) <https://github.com/pypa/pip/issues/11920>_)
Fix deprecation warnings in Python 3.12 for usage of shutil.rmtree ([#11957](https://github.com/pypa/pip/issues/11957) <https://github.com/pypa/pip/issues/11957>_)
Ignore invalid or unreadable origin.json files in the cache of locally built wheels. ([#11985](https://github.com/pypa/pip/issues/11985) <https://github.com/pypa/pip/issues/11985>_)
Fix installation of packages with PEP658 metadata using non-canonicalized names ([#12038](https://github.com/pypa/pip/issues/12038) <https://github.com/pypa/pip/issues/12038>_)
Correctly parse dist-info-metadata values from JSON-format index data. ([#12042](https://github.com/pypa/pip/issues/12042) <https://github.com/pypa/pip/issues/12042>_)
Fail with an error if the --python option is specified after the subcommand name. ([#12067](https://github.com/pypa/pip/issues/12067) <https://github.com/pypa/pip/issues/12067>_)
Fix slowness when using importlib.metadata (the default way for pip to read metadata in Python 3.11+) and there is a large overlap between already installed and to-be-installed packages. ([#12079](https://github.com/pypa/pip/issues/12079) <https://github.com/pypa/pip/issues/12079>_)
Pass the -r flag to mercurial to be explicit that a revision is passed and protect
against hg options injection as part of VCS URLs. Users that do not have control on
VCS URLs passed to pip are advised to upgrade. ([#12119](https://github.com/pypa/pip/issues/12119) <https://github.com/pypa/pip/issues/12119>_)
