Improve deprecation warning regarding the copying of source trees when installing from a local directory. ([#10128](https://github.com/pypa/pip/issues/10128) <https://github.com/pypa/pip/issues/10128>_)
Suppress location mismatch warnings when pip is invoked from a Python source
tree, so ensurepip does not emit warnings on CPython make install. ([#10270](https://github.com/pypa/pip/issues/10270) <https://github.com/pypa/pip/issues/10270>_)
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. ([#10358](https://github.com/pypa/pip/issues/10358) <https://github.com/pypa/pip/issues/10358>_)
Remove the --build-dir option and aliases, one last time. ([#10485](https://github.com/pypa/pip/issues/10485) <https://github.com/pypa/pip/issues/10485>_)
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. ([#10495](https://github.com/pypa/pip/issues/10495) <https://github.com/pypa/pip/issues/10495>_)
Un-deprecate source distribution re-installation behaviour. ([#8711](https://github.com/pypa/pip/issues/8711) <https://github.com/pypa/pip/issues/8711>_)
Features
Replace vendored appdirs with platformdirs. ([#10202](https://github.com/pypa/pip/issues/10202) <https://github.com/pypa/pip/issues/10202>_)
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. ([#10249](https://github.com/pypa/pip/issues/10249) <https://github.com/pypa/pip/issues/10249>_)
pip freeze will now always fallback to reporting the editable project
location when it encounters a VCS error while analyzing an editable
requirement. Before, it sometimes reported the requirement as non-editable. ([#10410](https://github.com/pypa/pip/issues/10410) <https://github.com/pypa/pip/issues/10410>_)
pip show now sorts Requires and Required-By alphabetically. ([#10422](https://github.com/pypa/pip/issues/10422) <https://github.com/pypa/pip/issues/10422>_)
Do not raise error when there are no files to remove with pip cache purge/remove.
Instead log a warning and continue (to log that we removed 0 files). ([#10459](https://github.com/pypa/pip/issues/10459) <https://github.com/pypa/pip/issues/10459>_)
When backtracking during dependency resolution, prefer the dependencies which are involved in the most recent conflict. This can significantly reduce the amount of backtracking required. ([#10479](https://github.com/pypa/pip/issues/10479) <https://github.com/pypa/pip/issues/10479>_)
Cache requirement objects, to improve performance reducing reparses of requirement strings. ([#10550](https://github.com/pypa/pip/issues/10550) <https://github.com/pypa/pip/issues/10550>_)
Support editable installs for projects that have a pyproject.toml and use a
build backend that supports :pep:660. ([#8212](https://github.com/pypa/pip/issues/8212) <https://github.com/pypa/pip/issues/8212>_)
When a revision is specified in a Git URL, use git's partial clone feature to speed up source retrieval. ([#9086](https://github.com/pypa/pip/issues/9086) <https://github.com/pypa/pip/issues/9086>_)
Add a --debug flag, to enable a mode that doesn't log errors and propagates them to the top level instead. This is primarily to aid with debugging pip's crashes. ([#9349](https://github.com/pypa/pip/issues/9349) <https://github.com/pypa/pip/issues/9349>_)
If a host is explicitly specified as trusted by the user (via the --trusted-host option), cache HTTP responses from it in addition to HTTPS ones. ([#9498](https://github.com/pypa/pip/issues/9498) <https://github.com/pypa/pip/issues/9498>_)
Bug Fixes
Present a better error message, when a file: URL is not found. ([#10263](https://github.com/pypa/pip/issues/10263) <https://github.com/pypa/pip/issues/10263>_)
Fix the auth credential cache to allow for the case in which
the index url contains the username, but the password comes
from an external source, such as keyring. ([#10269](https://github.com/pypa/pip/issues/10269) <https://github.com/pypa/pip/issues/10269>_)
Fix double unescape of HTML data-requires-python and data-yanked attributes. ([#10378](https://github.com/pypa/pip/issues/10378) <https://github.com/pypa/pip/issues/10378>_)
New resolver: Fixes depth ordering of packages during resolution, e.g. a dependency 2 levels deep will be ordered before a dependecy 3 levels deep. ([#10482](https://github.com/pypa/pip/issues/10482) <https://github.com/pypa/pip/issues/10482>_)
