 .. towncrier release notes start
 
+20.0 (2020-01-21)
+=================
+
+Process
+-------
+
+- Switch to a dedicated CLI tool for vendoring dependencies.
+
+Deprecations and Removals
+-------------------------
+
+- Remove wheel tag calculation from pip and use ``packaging.tags``. This
+  should provide more tags ordered better than in prior releases. (`#6908 <https://github.com/pypa/pip/issues/6908>`_)
+- Deprecate setup.py-based builds that do not generate an ``.egg-info`` directory. (`#6998 <https://github.com/pypa/pip/issues/6998>`_)
+- The pip>=20 wheel cache is not retro-compatible with previous versions. Until
+  pip 21.0, pip will continue to take advantage of existing legacy cache
+  entries. (`#7296 <https://github.com/pypa/pip/issues/7296>`_)
+- Deprecate undocumented ``--skip-requirements-regex`` option. (`#7297 <https://github.com/pypa/pip/issues/7297>`_)
+- Deprecate passing install-location-related options via ``--install-option``. (`#7309 <https://github.com/pypa/pip/issues/7309>`_)
+- Use literal "abi3" for wheel tag on CPython 3.x, to align with PEP 384
+  which only defines it for this platform. (`#7327 <https://github.com/pypa/pip/issues/7327>`_)
+- Remove interpreter-specific major version tag e.g. ``cp3-none-any``
+  from consideration. This behavior was not documented strictly, and this
+  tag in particular is `not useful <https://snarky.ca/the-challenges-in-designing-a-library-for-pep-425/>`_.
+  Anyone with a use case can create an issue with pypa/packaging. (`#7355 <https://github.com/pypa/pip/issues/7355>`_)
+- Wheel processing no longer permits wheels containing more than one top-level
+  .dist-info directory. (`#7487 <https://github.com/pypa/pip/issues/7487>`_)
+- Support for the ``git+git@`` form of VCS requirement is being deprecated and
+  will be removed in pip 21.0. Switch to ``git+https://`` or
+  ``git+ssh://``. ``git+git://`` also works but its use is discouraged as it is
+  insecure. (`#7543 <https://github.com/pypa/pip/issues/7543>`_)
+
+Features
+--------
+
+- Default to doing a user install (as if ``--user`` was passed) when the main
+  site-packages directory is not writeable and user site-packages are enabled. (`#1668 <https://github.com/pypa/pip/issues/1668>`_)
+- Warn if a path in PATH starts with tilde during ``pip install``. (`#6414 <https://github.com/pypa/pip/issues/6414>`_)
+- Cache wheels built from Git requirements that are considered immutable,
+  because they point to a commit hash. (`#6640 <https://github.com/pypa/pip/issues/6640>`_)
+- Add option ``--no-python-version-warning`` to silence warnings
+  related to deprecation of Python versions. (`#6673 <https://github.com/pypa/pip/issues/6673>`_)
+- Cache wheels that ``pip wheel`` built locally, matching what
+  ``pip install`` does. This particularly helps performance in workflows where
+  ``pip wheel`` is used for `building before installing
+  <https://pip.pypa.io/en/stable/user_guide/#installing-from-local-packages>`_.
+  Users desiring the original behavior can use ``pip wheel --no-cache-dir``. (`#6852 <https://github.com/pypa/pip/issues/6852>`_)
+- Display CA information in ``pip debug``. (`#7146 <https://github.com/pypa/pip/issues/7146>`_)
+- Show only the filename (instead of full URL), when downloading from PyPI. (`#7225 <https://github.com/pypa/pip/issues/7225>`_)
+- Suggest a more robust command to upgrade pip itself to avoid confusion when the
+  current pip command is not available as ``pip``. (`#7376 <https://github.com/pypa/pip/issues/7376>`_)
+- Define all old pip console script entrypoints to prevent import issues in
+  stale wrapper scripts. (`#7498 <https://github.com/pypa/pip/issues/7498>`_)
+- The build step of ``pip wheel`` now builds all wheels to a cache first,
+  then copies them to the wheel directory all at once.
+  Before, it built them to a temporary direcory and moved
+  them to the wheel directory one by one. (`#7517 <https://github.com/pypa/pip/issues/7517>`_)
+- Expand ``~`` prefix to user directory in path options, configs, and
+  environment variables. Values that may be either URL or path are not
+  currently supported, to avoid ambiguity:
+
+  * ``--find-links``
+  * ``--constraint``, ``-c``
+  * ``--requirement``, ``-r``
+  * ``--editable``, ``-e`` (`#980 <https://github.com/pypa/pip/issues/980>`_)
+
+Bug Fixes
+---------
+
+- Correctly handle system site-packages, in virtual environments created with venv (PEP 405). (`#5702 <https://github.com/pypa/pip/issues/5702>`_, `#7155 <https://github.com/pypa/pip/issues/7155>`_)
+- Fix case sensitive comparison of pip freeze when used with -r option. (`#5716 <https://github.com/pypa/pip/issues/5716>`_)
+- Enforce PEP 508 requirement format in ``pyproject.toml``
+  ``build-system.requires``. (`#6410 <https://github.com/pypa/pip/issues/6410>`_)
+- Make ``ensure_dir()`` also ignore ``ENOTEMPTY`` as seen on Windows. (`#6426 <https://github.com/pypa/pip/issues/6426>`_)
+- Fix building packages which specify ``backend-path`` in pyproject.toml. (`#6599 <https://github.com/pypa/pip/issues/6599>`_)
+- Do not attempt to run ``setup.py clean`` after a ``pep517`` build error,
+  since a ``setup.py`` may not exist in that case. (`#6642 <https://github.com/pypa/pip/issues/6642>`_)
+- Fix passwords being visible in the index-url in
+  "Downloading <url>" message. (`#6783 <https://github.com/pypa/pip/issues/6783>`_)
+- Change method from shutil.remove to shutil.rmtree in noxfile.py. (`#7191 <https://github.com/pypa/pip/issues/7191>`_)
+- Skip running tests which require subversion, when svn isn't installed (`#7193 <https://github.com/pypa/pip/issues/7193>`_)
+- Fix not sending client certificates when using ``--trusted-host``. (`#7207 <https://github.com/pypa/pip/issues/7207>`_)
+- Make sure ``pip wheel`` never outputs pure python wheels with a
+  python implementation tag. Better fix/workaround for
+  `#3025 <https://github.com/pypa/pip/issues/3025>`_ by
+  using a per-implementation wheel cache instead of caching pure python
+  wheels with an implementation tag in their name. (`#7296 <https://github.com/pypa/pip/issues/7296>`_)
+- Include ``subdirectory`` URL fragments in cache keys. (`#7333 <https://github.com/pypa/pip/issues/7333>`_)
+- Fix typo in warning message when any of ``--build-option``, ``--global-option``
+  and ``--install-option`` is used in requirements.txt (`#7340 <https://github.com/pypa/pip/issues/7340>`_)
+- Fix the logging of cached HTTP response shown as downloading. (`#7393 <https://github.com/pypa/pip/issues/7393>`_)
+- Effectively disable the wheel cache when it is not writable, as is the
+  case with the http cache. (`#7488 <https://github.com/pypa/pip/issues/7488>`_)
+- Correctly handle relative cache directory provided via --cache-dir. (`#7541 <https://github.com/pypa/pip/issues/7541>`_)
+

+
+Improved Documentation
+----------------------
+

+- Explain how to get pip's source code in `Getting Started <https://pip.pypa.io/en/stable/development/getting-started/>`_ (`#7197 <https://github.com/pypa/pip/issues/7197>`_)
+- Describe how basic authentication credentials in URLs work. (`#7201 <https://github.com/pypa/pip/issues/7201>`_)
+- Add more clear installation instructions (`#7222 <https://github.com/pypa/pip/issues/7222>`_)
