    py-pip: updated to 20.2

    20.2
    ====

    Deprecations and Removals
    -------------------------
    - Deprecate setup.py-based builds that do not generate an ``.egg-info`` directory.
    - Disallow passing install-location-related arguments in ``--install-options``.
    - Add deprecation warning for invalid requirements format "base>=1.0[extra]"
    - Deprecate legacy setup.py install when building a wheel failed for source
      distributions without pyproject.toml
    - Deprecate -b/--build/--build-dir/--build-directory. Its current behaviour is confusing
      and breaks in case different versions of the same distribution need to be built during
      the resolution process. Using the TMPDIR/TEMP/TMP environment variable, possibly
      combined with --no-clean covers known use cases.
    - Remove undocumented and deprecated option ``--always-unzip``

    Features
    --------
    - Log debugging information about pip, in ``pip install --verbose``.
    - Refine error messages to avoid showing Python tracebacks when an HTTP error occurs.
    - Install wheel files directly instead of extracting them to a temp directory.
    - Add a beta version of pip's next-generation dependency resolver.

      Move pip's new resolver into beta, remove the
      ``--unstable-feature=resolver`` flag, and enable the
      ``--use-feature=2020-resolver`` flag. The new resolver is
      significantly stricter and more consistent when it receives
      incompatible instructions, and reduces support for certain kinds of
      :ref:`Constraints Files`, so some workarounds and workflows may
      break. More details about how to test and migrate, and how to report
      issues, at :ref:`Resolver changes 2020` . Maintainers are preparing to
      release pip 20.3, with the new resolver on by default, in October.
    - Add a subcommand ``debug`` to ``pip config`` to list available configuration sources and the key-value pairs defined in them.
    - Warn if index pages have unexpected content-type
    - Allow specifying ``--prefer-binary`` option in a requirements file
    - Generate PEP 376 REQUESTED metadata for user supplied requirements installed
      by pip.
    - Warn if package url is a vcs or an archive url with invalid scheme
    - Parallelize network operations in ``pip list``.
    - Allow the new resolver to obtain dependency information through wheels
      lazily downloaded using HTTP range requests.  To enable this feature,
      invoke ``pip`` with ``--use-feature=fast-deps``.
    - Support ``--use-feature`` in requirements files

    Bug Fixes
    ---------
    - Use canonical package names while looking up already installed packages.
    - Fix normalizing path on Windows when installing package on another logical disk.
    - The VCS commands run by pip as subprocesses don't merge stdout and stderr anymore, improving the output parsing by subsequent commands.
    - Correctly treat non-ASCII entry point declarations in wheels so they can be
      installed on Windows.
    - Update author email in config and tests to reflect decommissioning of pypa-dev list.
    - Headers provided by wheels in .data directories are now correctly installed
      into the user-provided locations, such as ``--prefix``, instead of the virtual
      environment pip is running in.

    Vendored Libraries
    ------------------
    - Vendored htmlib5 no longer imports deprecated xml.etree.cElementTree on Python 3.
    - Upgrade appdirs to 1.4.4
    - Upgrade certifi to 2020.6.20
    - Upgrade distlib to 0.3.1
    - Upgrade html5lib to 1.1
    - Upgrade idna to 2.10
    - Upgrade packaging to 20.4
    - Upgrade requests to 2.24.0
    - Upgrade six to 1.15.0
    - Upgrade toml to 0.10.1
    - Upgrade urllib3 to 1.25.9

    Improved Documentation
    ----------------------
    - Add ``--no-input`` option to pip docs
    - List of options supported in requirements file are extracted from source of truth,
      instead of being maintained manually.
    - Fix pip config docstring so that the subcommands render correctly in the docs
    - replace links to the old pypa-dev mailing list with https://mail.python.org/mailman3/lists/distutils-sig.python.org/
    - Fix example for defining multiple values for options which support them
    - Add documentation that helps the user fix dependency conflicts
    - Add feature flags to docs
    - Document how to install package extras from git branch and source distributions.
