* Always refuse installing or building projects that have no ``pyproject.toml`` nor
``setup.py``.
* Tweak running-as-root detection, to check ``os.getuid`` if it exists, on
Unix-y and non-Linux/non-MacOS machines.
* When installing projects with a ``pyproject.toml`` in editable mode, and the build
backend does not support :pep:`660`, prepare metadata using
``prepare_metadata_for_build_wheel`` instead of ``setup.py egg_info``. Also, refuse
installing projects that only have a ``setup.cfg`` and no ``setup.py`` nor
``pyproject.toml``. These restore the pre-21.3 behaviour.
* Restore compatibility of where configuration files are loaded from on MacOS
* Upgrade pep517 to 0.12.0
* Improve deprecation warning regarding the copying of source trees when
installing from a local directory.
* Suppress location mismatch warnings when pip is invoked from a Python source
tree, so ``ensurepip`` does not emit warnings on CPython ``make install``.
* On Python 3.10 or later, the installation scheme backend has been changed to use
``sysconfig``. This is to anticipate the deprecation of ``distutils`` in Python
3.10, and its scheduled removal in 3.12. For compatibility considerations, pip
installations running on Python 3.9 or lower will continue to use ``distutils``.
* Remove the ``--build-dir`` option and aliases, one last time.
* In-tree builds are now the default. ``--use-feature=in-tree-build`` is now
ignored. ``--use-deprecated=out-of-tree-build`` may be used temporarily to ease
the transition.
* Un-deprecate source distribution re-installation behaviour.
* Replace vendored appdirs with platformdirs.
* Support `PEP 610 <https://www.python.org/dev/peps/pep-0610/>`_ to detect
editable installs in ``pip freeze`` and ``pip list``. The ``pip list`` column output
has a new ``Editable project location`` column, and the JSON output has a new
``editable_project_location`` field.
