.. towncrier release notes start
20.3b1 (2020-10-31)
===================
Deprecations and Removals
-------------------------
- ``pip freeze`` will stop filtering the ``pip``, ``setuptools``, ``distribute`` and ``wheel`` packages from ``pip freeze`` output in a future version.
To keep the previous behavior, users should use the new ``--exclude`` option. (`#4256 <https://github.com/pypa/pip/issues/4256>`_)
- Deprecate support for Python 3.5 (`#8181 <https://github.com/pypa/pip/issues/8181>`_)
- Document that certain removals can be fast tracked. (`#8417 <https://github.com/pypa/pip/issues/8417>`_)
- Document that Python versions are generally supported until PyPI usage falls below 5%. (`#8927 <https://github.com/pypa/pip/issues/8927>`_)
- Deprecate ``--find-links`` option in ``pip freeze`` (`#9069 <https://github.com/pypa/pip/issues/9069>`_)
Features
--------
- Add ``--exclude`` option to ``pip freeze`` and ``pip list`` commands to explicitly exclude packages from the output. (`#4256 <https://github.com/pypa/pip/issues/4256>`_)
- Allow multiple values for --abi and --platform. (`#6121 <https://github.com/pypa/pip/issues/6121>`_)
- Add option ``--format`` to subcommand ``list`` of ``pip cache``, with ``abspath`` choice to output the full path of a wheel file. (`#8355 <https://github.com/pypa/pip/issues/8355>`_)
- Improve error message friendliness when an environment has packages with
corrupted metadata. (`#8676 <https://github.com/pypa/pip/issues/8676>`_)
- Make the ``setup.py install`` deprecation warning less noisy. We warn only
when ``setup.py install`` succeeded and ``setup.py bdist_wheel`` failed, as
situations where both fails are most probably irrelevant to this deprecation. (`#8752 <https://github.com/pypa/pip/issues/8752>`_)
- Check the download directory for existing wheels to possibly avoid
fetching metadata when the ``fast-deps`` feature is used with
``pip wheel`` and ``pip download``. (`#8804 <https://github.com/pypa/pip/issues/8804>`_)
- When installing a git URL that refers to a commit that is not available locally
after git clone, attempt to fetch it from the remote. (`#8815 <https://github.com/pypa/pip/issues/8815>`_)
- Include http subdirectory in ``pip cache info`` and ``pip cache purge`` commands. (`#8892 <https://github.com/pypa/pip/issues/8892>`_)
- Cache package listings on index packages so they are guarenteed to stay stable
during a pip command session. This also improves performance when a index page
is accessed multiple times during the command session. (`#8905 <https://github.com/pypa/pip/issues/8905>`_)
- New resolver: Tweak resolution logic to improve user experience when
user-supplied requirements conflict. (`#8924 <https://github.com/pypa/pip/issues/8924>`_)
- Support Python 3.9. (`#8971 <https://github.com/pypa/pip/issues/8971>`_)
- Log an informational message when backtracking takes multiple rounds on a specific package. (`#8975 <https://github.com/pypa/pip/issues/8975>`_)
- Switch to the new dependency resolver by default. (`#9019 <https://github.com/pypa/pip/issues/9019>`_)
- Remove the ``--build-dir`` option, as per the deprecation. (`#9049 <https://github.com/pypa/pip/issues/9049>`_)
Bug Fixes
---------
- Propagate ``--extra-index-url`` from requirements file properly to session auth,
so that keyring auth will work as expected. (`#8103 <https://github.com/pypa/pip/issues/8103>`_)
- Allow specifying verbosity and quiet level via configuration files
and environment variables. Previously these options were treated as
boolean values when read from there while through CLI the level can be
specified. (`#8578 <https://github.com/pypa/pip/issues/8578>`_)
- Only converts Windows path to unicode on Python 2 to avoid regressions when a
POSIX environment does not configure the file system encoding correctly. (`#8658 <https://github.com/pypa/pip/issues/8658>`_)
- List downloaded distributions before exiting ``pip download``
when using the new resolver to make the behavior the same as
that on the legacy resolver. (`#8696 <https://github.com/pypa/pip/issues/8696>`_)
- New resolver: Pick up hash declarations in constraints files and use them to
filter available distributions. (`#8792 <https://github.com/pypa/pip/issues/8792>`_)
- Avoid polluting the destination directory by resolution artifacts
when the new resolver is used for ``pip download`` or ``pip wheel``. (`#8827 <https://github.com/pypa/pip/issues/8827>`_)
- New resolver: If a package appears multiple times in user specification with
different ``--hash`` options, only hashes that present in all specifications
should be allowed. (`#8839 <https://github.com/pypa/pip/issues/8839>`_)
- Tweak the output during dependency resolution in the new resolver. (`#8861 <https://github.com/pypa/pip/issues/8861>`_)
- Correctly search for installed distributions in new resolver logic in order
to not miss packages (virtualenv packages from system-wide-packages for example) (`#8963 <https://github.com/pypa/pip/issues/8963>`_)
- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file
with editable=True. Render it as a non-editable ``file://`` URL until modern
editable installs are standardized and supported. (`#8996 <https://github.com/pypa/pip/issues/8996>`_)
Vendored Libraries
------------------
- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed.
It is mandatory for ``pip debug`` command.
Improved Documentation
----------------------
- Add documentation for '.netrc' support. (`#7231 <https://github.com/pypa/pip/issues/7231>`_)
- Add OS tabs for OS-specific commands. (`#7311 <https://github.com/pypa/pip/issues/7311>`_)
- Add note and example on keyring support for index basic-auth (`#8636 <https://github.com/pypa/pip/issues/8636>`_)
- Added initial UX feedback widgets to docs. (`#8783 <https://github.com/pypa/pip/issues/8783>`_, `#8848 <https://github.com/pypa/pip/issues/8848>`_)
- Add ux documentation (`#8807 <https://github.com/pypa/pip/issues/8807>`_)
- Update user docs to reflect new resolver as default in 20.3. (`#9044 <https://github.com/pypa/pip/issues/9044>`_)
- Improve migration guide to reflect changes in new resolver behavior. (`#9056 <https://github.com/pypa/pip/issues/9056>`_)
