Changelog
### 20.2.4
```
===================
Deprecations and Removals
-------------------------
- 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>`_)
Features
--------
- New resolver: Avoid accessing indexes when the installed candidate is preferred
and considered good enough. (`8023 <https://github.com/pypa/pip/issues/8023>`_)
- Improve error message friendliness when an environment has packages with
corrupted metadata. (`8676 <https://github.com/pypa/pip/issues/8676>`_)
- 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>`_)
Bug Fixes
---------
- New resolver: Correctly respect ``Requires-Python`` metadata to reject
incompatible packages in ``--no-deps`` mode. (`8758 <https://github.com/pypa/pip/issues/8758>`_)
- New resolver: Pick up hash declarations in constraints files and use them to
filter available distributions. (`8792 <https://github.com/pypa/pip/issues/8792>`_)
- 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>`_)
Improved Documentation
----------------------
- Add ux documentation (`8807 <https://github.com/pypa/pip/issues/8807>`_)
```
### 20.2.3
```
===================
Deprecations and Removals
-------------------------
- Deprecate support for Python 3.5 (`8181 <https://github.com/pypa/pip/issues/8181>`_)
Features
--------
- 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>`_)
```
### 20.2.2
```
===================
Bug Fixes
---------
- Only attempt to use the keyring once and if it fails, don't try again.
This prevents spamming users with several keyring unlock prompts when they
cannot unlock or don't want to do so. (`8090 <https://github.com/pypa/pip/issues/8090>`_)
- Fix regression that distributions in system site-packages are not correctly
found when a virtual environment is configured with ``system-site-packages``
on. (`8695 <https://github.com/pypa/pip/issues/8695>`_)
- Disable caching for range requests, which causes corrupted wheels
when pip tries to obtain metadata using the feature ``fast-deps``. (`8701 <https://github.com/pypa/pip/issues/8701>`_, `8716 <https://github.com/pypa/pip/issues/8716>`_)
- Always use UTF-8 to read ``pyvenv.cfg`` to match the built-in ``venv``. (`8717 <https://github.com/pypa/pip/issues/8717>`_)
- 2020 Resolver: Correctly handle marker evaluation in constraints and exclude
them if their markers do not match the current environment. (`8724 <https://github.com/pypa/pip/issues/8724>`_)
```
### 20.2.1
```
===================
Features
--------
- Ignore require-virtualenv in ``pip list`` (`8603 <https://github.com/pypa/pip/issues/8603>`_)
Bug Fixes
---------
- Correctly find already-installed distributions with dot (``.``) in the name
and uninstall them when needed. (`8645 <https://github.com/pypa/pip/issues/8645>`_)
- Trace a better error message on installation failure due to invalid ``.data``
files in wheels. (`8654 <https://github.com/pypa/pip/issues/8654>`_)
- Fix SVN version detection for alternative SVN distributions. (`8665 <https://github.com/pypa/pip/issues/8665>`_)
- New resolver: Correctly include the base package when specified with extras
in ``--no-deps`` mode. (`8677 <https://github.com/pypa/pip/issues/8677>`_)
- Use UTF-8 to handle ZIP archive entries on Python 2 according to PEP 427, so
non-ASCII paths can be resolved as expected. (`8684 <https://github.com/pypa/pip/issues/8684>`_)
Improved Documentation
----------------------
- Add details on old resolver deprecation and removal to migration documentation. (`8371 <https://github.com/pypa/pip/issues/8371>`_)
- Fix feature flag name in docs. (`8660 <https://github.com/pypa/pip/issues/8660>`_)
```
### 20.2
```
=================
Deprecations and Removals
-------------------------
- Deprecate setup.py-based builds that do not generate an ``.egg-info`` directory. (`6998 <https://github.com/pypa/pip/issues/6998>`_, `8617 <https://github.com/pypa/pip/issues/8617>`_)
- Disallow passing install-location-related arguments in ``--install-options``. (`7309 <https://github.com/pypa/pip/issues/7309>`_)
- Add deprecation warning for invalid requirements format "base>=1.0[extra]" (`8288 <https://github.com/pypa/pip/issues/8288>`_)
- Deprecate legacy setup.py install when building a wheel failed for source
distributions without pyproject.toml (`8368 <https://github.com/pypa/pip/issues/8368>`_)
- 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. (`8372 <https://github.com/pypa/pip/issues/8372>`_)
- Remove undocumented and deprecated option ``--always-unzip`` (`8408 <https://github.com/pypa/pip/issues/8408>`_)
Features
--------
- Log debugging information about pip, in ``pip install --verbose``. (`3166 <https://github.com/pypa/pip/issues/3166>`_)
- Refine error messages to avoid showing Python tracebacks when an HTTP error occurs. (`5380 <https://github.com/pypa/pip/issues/5380>`_)
- Install wheel files directly instead of extracting them to a temp directory. (`6030 <https://github.com/pypa/pip/issues/6030>`_)
- 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
```
### 20.2b1
```
===================
Bug Fixes
---------
- Correctly treat wheels containing non-ASCII file contents so they can be
installed on Windows. (`5712 <https://github.com/pypa/pip/issues/5712>`_)
- Prompt the user for password if the keyring backend doesn't return one (`7998 <https://github.com/pypa/pip/issues/7998>`_)
Improved Documentation
----------------------
- Add GitHub issue template for reporting when the dependency resolver fails (`8207 <https://github.com/pypa/pip/issues/8207>`_)
```
### 20.1.1
```
===================
Deprecations and Removals
-------------------------
- Revert building of local directories in place, restoring the pre-20.1
behaviour of copying to a temporary directory. (`7555 <https://github.com/pypa/pip/issues/7555>`_)
- Drop parallelization from ``pip list --outdated``. (`8167 <https://github.com/pypa/pip/issues/8167>`_)
Bug Fixes
---------
- Fix metadata permission issues when umask has the executable bit set. (`8164 <https://github.com/pypa/pip/issues/8164>`_)
- Avoid unnecessary message about the wheel package not being installed
when a wheel would not have been built. Additionally, clarify the message. (`8178 <https://github.com/pypa/pip/issues/8178>`_)
```
### 20.1
```
=================
Process
-------
- Document that pip 21.0 will drop support for Python 2.7.
Features
--------
- Add ``pip cache dir`` to show the cache directory. (`7350 <https://github.com/pypa/pip/issues/7350>`_)
Bug Fixes
---------
- Abort pip cache commands early when cache is disabled. (`8124 <https://github.com/pypa/pip/issues/8124>`_)
- Correctly set permissions on metadata files during wheel installation,
to permit non-privileged users to read from system site-packages. (`8139 <https://github.com/pypa/pip/issues/8139>`_)
```
### 20.1b1
```
===================
Deprecations and Removals
-------------------------
- Remove emails from AUTHORS.txt to prevent usage for spamming, and only populate names in AUTHORS.txt at time of release (`5979 <https://github.com/pypa/pip/issues/5979>`_)
- Remove deprecated ``--skip-requirements-regex`` option. (`7297 <https://github.com/pypa/pip/issues/7297>`_)
- Building of local directories is now done in place, instead of a temporary
location containing a copy of the directory tree. (`7555 <https://github.com/pypa/pip/issues/7555>`_)
- Remove unused ``tests/scripts/test_all_pip.py`` test script and the ``tests/scripts`` folder. (`7680 <https://github.com/pypa/pip/issues/7680>`_)
Features
--------
- pip now implements PEP 610, so ``pip freeze`` has better fidelity
in presence of distributions installed from Direct URL requirements. (`609 <https://github.com/pypa/pip/issues/609>`_)
- Add ``pip cache`` command for inspecting/managing pip's wheel cache. (`6391 <https://github.com/pypa/pip/issues/6391>`_)
- Raise error if ``--user`` and ``--target`` are used together in ``pip install`` (`7249 <https://github.com/pypa/pip/issues/7249>`_)
- Significantly improve performance when ``--find-links`` points to a very large HTML page. (`7729 <https://github.com/pypa/pip/issues/7729>`_)
- Indicate when wheel building is skipped, due to lack of the ``wheel`` package. (`7768 <https://github.com/pypa/pip/issues/7768>`_)
- Change default behaviour to always cache responses from trusted-host source. (`7847 <https://github.com/pypa/pip/issues/7847>`_)
- An alpha version of a new resolver is available via ``--unstable-feature=resolver``. (`988 <https://github.com/pypa/pip/issues/988>`_)
Bug Fixes
---------
- Correctly freeze a VCS editable package when it is nested inside another VCS repository. (`3988 <https://github.com/pypa/pip/issues/3988>`_)
- Correctly handle ``%2F`` in URL parameters to avoid accidentally unescape them
into ``/``. (`6446 <https://github.com/pypa/pip/issues/6446>`_)
- Reject VCS URLs with an empty revision. (`7402 <https://github.com/pypa/pip/issues/7402>`_)
- Warn when an invalid URL is passed with ``--index-url`` (`7430 <https://github.com/pypa/pip/issues/7430>`_)
- Use better mechanism for handling temporary files, when recording metadata
about installed files (RECORD) and the installer (INSTALLER). (`7699 <https://github.com/pypa/pip/issues/7699>`_)
- Correctly detect global site-packages availability of virtual environments
created by PyPA’s virtualenv>=20.0. (`7718 <https://github.com/pypa/pip/issues/7718>`_)
- Remove current directory from ``sys.path`` when invoked as ``python -m pip <command>`` (`7731 <https://github.com/pypa/pip/issues/7731>`_)
- Stop failing uninstallation, when trying to remove non-existent files. (`7856 <https://github.com/pypa/pip/issues/7856>`_)
- Prevent an infinite recursion with ``pip wheel`` when ``$TMPDIR`` is within the source directory. (`7872 <https://github.com/pypa/pip/issues/7872>`_)
- Significantly speedup ``pip list --outdated`` by parallelizing index interaction. (`7962 <https://github.com/pypa/pip/issues/7962>`_)
- Improve Windows compatibility when detecting writability in folder. (`8013 <https://github.com/pypa/pip/issues/8013>`_)

- Clarify the usage of freeze command in the example of Using pip in your program (`7008 <https://github.com/pypa/pip/issues/7008>`_)
- Add a "Copyright" page. (`7767 <https://github.com/pypa/pip/issues/7767>`_)
- Added example of defining multiple values for options which support them (`7803 <https://github.com/pypa/pip/issues/7803>`_)
```
### 20.0.2
```
===================
Bug Fixes
---------
- Fix a regression in generation of compatibility tags. (`7626 <https://github.com/pypa/pip/issues/7626>`_)
Vendored Libraries
------------------
- Upgrade packaging to 20.1
```
### 20.0.1
```
===================
Bug Fixes
---------
- Rename an internal module, to avoid ImportErrors due to improper uninstallation. (`7621 <https://github.com/pypa/pip/issues/7621>`_)
```
### 20.0
```
=================
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 directory 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>`_)
Vendored Libraries

- 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>`_)
- Fix documentation links for index options (`7347 <https://github.com/pypa/pip/issues/7347>`_)
- Better document the requirements file format (`7385 <https://github.com/pypa/pip/issues/7385>`_)
```
### 19.3.1

- Document Python 3.8 support. (`7219 <https://github.com/pypa/pip/issues/7219>`_)
Bug Fixes
---------
- Fix bug that prevented installation of PEP 517 packages without ``setup.py``. (`6606 <https://github.com/pypa/pip/issues/6606>`_)
```
### 19.3
```
=================
Deprecations and Removals
-------------------------
- Remove undocumented support for un-prefixed URL requirements pointing
to SVN repositories. Users relying on this can get the original behavior
by prefixing their URL with ``svn+`` (which is backwards-compatible). (`7037 <https://github.com/pypa/pip/issues/7037>`_)
- Remove the deprecated ``--venv`` option from ``pip config``. (`7163 <https://github.com/pypa/pip/issues/7163>`_)
Features
--------
- Print a better error message when ``--no-binary`` or ``--only-binary`` is given
an argument starting with ``-``. (`3191 <https://github.com/pypa/pip/issues/3191>`_)
- Make ``pip show`` warn about packages not found. (`6858 <https://github.com/pypa/pip/issues/6858>`_)
- Support including a port number in ``--trusted-host`` for both HTTP and HTTPS. (`6886 <https://github.com/pypa/pip/issues/6886>`_)
- Redact single-part login credentials from URLs in log messages. (`6891 <https://github.com/pypa/pip/issues/6891>`_)
- Implement manylinux2014 platform tag support. manylinux2014 is the successor
to manylinux2010. It allows carefully compiled binary wheels to be installed
on compatible Linux platforms. The manylinux2014 platform tag definition can
be found in `PEP599 <https://www.python.org/dev/peps/pep-0599/>`_. (`7102 <https://github.com/pypa/pip/issues/7102>`_)
Bug Fixes
---------
- Abort installation if any archive contains a file which would be placed
outside the extraction location. (`3907 <https://github.com/pypa/pip/issues/3907>`_)
- pip's CLI completion code no longer prints a Traceback if it is interrupted. (`3942 <https://github.com/pypa/pip/issues/3942>`_)
- Correct inconsistency related to the ``hg+file`` scheme. (`4358 <https://github.com/pypa/pip/issues/4358>`_)
- Fix ``rmtree_errorhandler`` to skip non-existing directories. (`4910 <https://github.com/pypa/pip/issues/4910>`_)
- Ignore errors copying socket files for local source installs (in Python 3). (`5306 <https://github.com/pypa/pip/issues/5306>`_)
- Fix requirement line parser to correctly handle PEP 440 requirements with a URL
pointing to an archive file. (`6202 <https://github.com/pypa/pip/issues/6202>`_)
- The ``pip-wheel-metadata`` directory does not need to persist between invocations of pip, use a temporary directory instead of the current ``setup.py`` directory. (`6213 <https://github.com/pypa/pip/issues/6213>`_)
- Fix ``--trusted-host`` processing under HTTPS to trust any port number used
with the host. (`6705 <https://github.com/pypa/pip/issues/6705>`_)
- Switch to new ``distlib`` wheel script template. This should be functionally
equivalent for end users. (`6763 <https://github.com/pypa/pip/issues/6763>`_)
- Skip copying .tox and .nox directories to temporary build directories (`6770 <https://github.com/pypa/pip/issues/6770>`_)
- Fix handling of tokens (single part credentials) in URLs. (`6795 <https://github.com/pypa/pip/issues/6795>`_)
- Fix a regression that caused ``~`` expansion not to occur in ``--find-links``

Changelog
### 20.2.4 ``` =================== Deprecations and Removals ------------------------- - 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>`_) Features -------- - New resolver: Avoid accessing indexes when the installed candidate is preferred and considered good enough. (`8023 <https://github.com/pypa/pip/issues/8023>`_) - Improve error message friendliness when an environment has packages with corrupted metadata. (`8676 <https://github.com/pypa/pip/issues/8676>`_) - 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>`_) Bug Fixes --------- - New resolver: Correctly respect ``Requires-Python`` metadata to reject incompatible packages in ``--no-deps`` mode. (`8758 <https://github.com/pypa/pip/issues/8758>`_) - New resolver: Pick up hash declarations in constraints files and use them to filter available distributions. (`8792 <https://github.com/pypa/pip/issues/8792>`_) - 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>`_) Improved Documentation ---------------------- - Add ux documentation (`8807 <https://github.com/pypa/pip/issues/8807>`_) ``` ### 20.2.3 ``` =================== Deprecations and Removals ------------------------- - Deprecate support for Python 3.5 (`8181 <https://github.com/pypa/pip/issues/8181>`_) Features -------- - 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>`_) ``` ### 20.2.2 ``` =================== Bug Fixes --------- - Only attempt to use the keyring once and if it fails, don't try again. This prevents spamming users with several keyring unlock prompts when they cannot unlock or don't want to do so. (`8090 <https://github.com/pypa/pip/issues/8090>`_) - Fix regression that distributions in system site-packages are not correctly found when a virtual environment is configured with ``system-site-packages`` on. (`8695 <https://github.com/pypa/pip/issues/8695>`_) - Disable caching for range requests, which causes corrupted wheels when pip tries to obtain metadata using the feature ``fast-deps``. (`8701 <https://github.com/pypa/pip/issues/8701>`_, `8716 <https://github.com/pypa/pip/issues/8716>`_) - Always use UTF-8 to read ``pyvenv.cfg`` to match the built-in ``venv``. (`8717 <https://github.com/pypa/pip/issues/8717>`_) - 2020 Resolver: Correctly handle marker evaluation in constraints and exclude them if their markers do not match the current environment. (`8724 <https://github.com/pypa/pip/issues/8724>`_) ``` ### 20.2.1 ``` =================== Features -------- - Ignore require-virtualenv in ``pip list`` (`8603 <https://github.com/pypa/pip/issues/8603>`_) Bug Fixes --------- - Correctly find already-installed distributions with dot (``.``) in the name and uninstall them when needed. (`8645 <https://github.com/pypa/pip/issues/8645>`_) - Trace a better error message on installation failure due to invalid ``.data`` files in wheels. (`8654 <https://github.com/pypa/pip/issues/8654>`_) - Fix SVN version detection for alternative SVN distributions. (`8665 <https://github.com/pypa/pip/issues/8665>`_) - New resolver: Correctly include the base package when specified with extras in ``--no-deps`` mode. (`8677 <https://github.com/pypa/pip/issues/8677>`_) - Use UTF-8 to handle ZIP archive entries on Python 2 according to PEP 427, so non-ASCII paths can be resolved as expected. (`8684 <https://github.com/pypa/pip/issues/8684>`_) Improved Documentation ---------------------- - Add details on old resolver deprecation and removal to migration documentation. (`8371 <https://github.com/pypa/pip/issues/8371>`_) - Fix feature flag name in docs. (`8660 <https://github.com/pypa/pip/issues/8660>`_) ``` ### 20.2 ``` ================= Deprecations and Removals ------------------------- - Deprecate setup.py-based builds that do not generate an ``.egg-info`` directory. (`6998 <https://github.com/pypa/pip/issues/6998>`_, `8617 <https://github.com/pypa/pip/issues/8617>`_) - Disallow passing install-location-related arguments in ``--install-options``. (`7309 <https://github.com/pypa/pip/issues/7309>`_) - Add deprecation warning for invalid requirements format "base>=1.0[extra]" (`8288 <https://github.com/pypa/pip/issues/8288>`_) - Deprecate legacy setup.py install when building a wheel failed for source distributions without pyproject.toml (`8368 <https://github.com/pypa/pip/issues/8368>`_) - 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. (`8372 <https://github.com/pypa/pip/issues/8372>`_) - Remove undocumented and deprecated option ``--always-unzip`` (`8408 <https://github.com/pypa/pip/issues/8408>`_) Features -------- - Log debugging information about pip, in ``pip install --verbose``. (`3166 <https://github.com/pypa/pip/issues/3166>`_) - Refine error messages to avoid showing Python tracebacks when an HTTP error occurs. (`5380 <https://github.com/pypa/pip/issues/5380>`_) - Install wheel files directly instead of extracting them to a temp directory. (`6030 <https://github.com/pypa/pip/issues/6030>`_) - 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 ``` ### 20.2b1 ``` =================== Bug Fixes --------- - Correctly treat wheels containing non-ASCII file contents so they can be installed on Windows. (`5712 <https://github.com/pypa/pip/issues/5712>`_) - Prompt the user for password if the keyring backend doesn't return one (`7998 <https://github.com/pypa/pip/issues/7998>`_) Improved Documentation ---------------------- - Add GitHub issue template for reporting when the dependency resolver fails (`8207 <https://github.com/pypa/pip/issues/8207>`_) ``` ### 20.1.1 ``` =================== Deprecations and Removals ------------------------- - Revert building of local directories in place, restoring the pre-20.1 behaviour of copying to a temporary directory. (`7555 <https://github.com/pypa/pip/issues/7555>`_) - Drop parallelization from ``pip list --outdated``. (`8167 <https://github.com/pypa/pip/issues/8167>`_) Bug Fixes --------- - Fix metadata permission issues when umask has the executable bit set. (`8164 <https://github.com/pypa/pip/issues/8164>`_) - Avoid unnecessary message about the wheel package not being installed when a wheel would not have been built. Additionally, clarify the message. (`8178 <https://github.com/pypa/pip/issues/8178>`_) ``` ### 20.1 ``` ================= Process ------- - Document that pip 21.0 will drop support for Python 2.7. Features -------- - Add ``pip cache dir`` to show the cache directory. (`7350 <https://github.com/pypa/pip/issues/7350>`_) Bug Fixes --------- - Abort pip cache commands early when cache is disabled. (`8124 <https://github.com/pypa/pip/issues/8124>`_) - Correctly set permissions on metadata files during wheel installation, to permit non-privileged users to read from system site-packages. (`8139 <https://github.com/pypa/pip/issues/8139>`_) ``` ### 20.1b1 ``` =================== Deprecations and Removals ------------------------- - Remove emails from AUTHORS.txt to prevent usage for spamming, and only populate names in AUTHORS.txt at time of release (`5979 <https://github.com/pypa/pip/issues/5979>`_) - Remove deprecated ``--skip-requirements-regex`` option. (`7297 <https://github.com/pypa/pip/issues/7297>`_) - Building of local directories is now done in place, instead of a temporary location containing a copy of the directory tree. (`7555 <https://github.com/pypa/pip/issues/7555>`_) - Remove unused ``tests/scripts/test_all_pip.py`` test script and the ``tests/scripts`` folder. (`7680 <https://github.com/pypa/pip/issues/7680>`_) Features -------- - pip now implements PEP 610, so ``pip freeze`` has better fidelity in presence of distributions installed from Direct URL requirements. (`609 <https://github.com/pypa/pip/issues/609>`_) - Add ``pip cache`` command for inspecting/managing pip's wheel cache. (`6391 <https://github.com/pypa/pip/issues/6391>`_) - Raise error if ``--user`` and ``--target`` are used together in ``pip install`` (`7249 <https://github.com/pypa/pip/issues/7249>`_) - Significantly improve performance when ``--find-links`` points to a very large HTML page. (`7729 <https://github.com/pypa/pip/issues/7729>`_) - Indicate when wheel building is skipped, due to lack of the ``wheel`` package. (`7768 <https://github.com/pypa/pip/issues/7768>`_) - Change default behaviour to always cache responses from trusted-host source. (`7847 <https://github.com/pypa/pip/issues/7847>`_) - An alpha version of a new resolver is available via ``--unstable-feature=resolver``. (`988 <https://github.com/pypa/pip/issues/988>`_) Bug Fixes --------- - Correctly freeze a VCS editable package when it is nested inside another VCS repository. (`3988 <https://github.com/pypa/pip/issues/3988>`_) - Correctly handle ``%2F`` in URL parameters to avoid accidentally unescape them into ``/``. (`6446 <https://github.com/pypa/pip/issues/6446>`_) - Reject VCS URLs with an empty revision. (`7402 <https://github.com/pypa/pip/issues/7402>`_) - Warn when an invalid URL is passed with ``--index-url`` (`7430 <https://github.com/pypa/pip/issues/7430>`_) - Use better mechanism for handling temporary files, when recording metadata about installed files (RECORD) and the installer (INSTALLER). (`7699 <https://github.com/pypa/pip/issues/7699>`_) - Correctly detect global site-packages availability of virtual environments created by PyPA’s virtualenv>=20.0. (`7718 <https://github.com/pypa/pip/issues/7718>`_) - Remove current directory from ``sys.path`` when invoked as ``python -m pip <command>`` (`7731 <https://github.com/pypa/pip/issues/7731>`_) - Stop failing uninstallation, when trying to remove non-existent files. (`7856 <https://github.com/pypa/pip/issues/7856>`_) - Prevent an infinite recursion with ``pip wheel`` when ``$TMPDIR`` is within the source directory. (`7872 <https://github.com/pypa/pip/issues/7872>`_) - Significantly speedup ``pip list --outdated`` by parallelizing index interaction. (`7962 <https://github.com/pypa/pip/issues/7962>`_) - Improve Windows compatibility when detecting writability in folder. (`8013 <https://github.com/pypa/pip/issues/8013>`_) Vendored Libraries ------------------ - Update semi-supported debundling script to reflect that appdirs is vendored. - Add ResolveLib as a vendored dependency. - Upgrade certifi to 2020.04.05.1 - Upgrade contextlib2 to 0.6.0.post1 - Upgrade distro to 1.5.0. - Upgrade idna to 2.9. - Upgrade msgpack to 1.0.0. - Upgrade packaging to 20.3. - Upgrade pep517 to 0.8.2. - Upgrade pyparsing to 2.4.7. - Remove pytoml as a vendored dependency. - Upgrade requests to 2.23.0. - Add toml as a vendored dependency. - Upgrade urllib3 to 1.25.8. Improved Documentation ---------------------- - Emphasize that VCS URLs using git, git+git and git+http are insecure due to lack of authentication and encryption (`1983 <https://github.com/pypa/pip/issues/1983>`_) - Clarify the usage of --no-binary command. (`3191 <https://github.com/pypa/pip/issues/3191>`_) - Clarify the usage of freeze command in the example of Using pip in your program (`7008 <https://github.com/pypa/pip/issues/7008>`_) - Add a "Copyright" page. (`7767 <https://github.com/pypa/pip/issues/7767>`_) - Added example of defining multiple values for options which support them (`7803 <https://github.com/pypa/pip/issues/7803>`_) ``` ### 20.0.2 ``` =================== Bug Fixes --------- - Fix a regression in generation of compatibility tags. (`7626 <https://github.com/pypa/pip/issues/7626>`_) Vendored Libraries ------------------ - Upgrade packaging to 20.1 ``` ### 20.0.1 ``` =================== Bug Fixes --------- - Rename an internal module, to avoid ImportErrors due to improper uninstallation. (`7621 <https://github.com/pypa/pip/issues/7621>`_) ``` ### 20.0 ``` ================= 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 directory 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.

(`7219 <https://github.com/pypa/pip/issues/7219>`_) Bug Fixes --------- - Fix bug that prevented installation of PEP 517 packages without ``setup.py``. (`6606 <https://github.com/pypa/pip/issues/6606>`_) ``` ### 19.3 ``` ================= Deprecations and Removals ------------------------- - Remove undocumented support for un-prefixed URL requirements pointing to SVN repositories. Users relying on this can get the original behavior by prefixing their URL with ``svn+`` (which is backwards-compatible). (`7037 <https://github.com/pypa/pip/issues/7037>`_) - Remove the deprecated ``--venv`` option from ``pip config``. (`7163 <https://github.com/pypa/pip/issues/7163>`_) Features -------- - Print a better error message when ``--no-binary`` or ``--only-binary`` is given an argument starting with ``-``.

(`6858 <https://github.com/pypa/pip/issues/6858>`_) - Support including a port number in ``--trusted-host`` for both HTTP and HTTPS. (`6886 <https://github.com/pypa/pip/issues/6886>`_) - Redact single-part login credentials from URLs in log messages. (`6891 <https://github.com/pypa/pip/issues/6891>`_) - Implement manylinux2014 platform tag support. manylinux2014 is the successor to manylinux2010. It allows carefully compiled binary wheels to be installed on compatible Linux platforms. The manylinux2014 platform tag definition can be found in `PEP599 <https://www.python.org/dev/peps/pep-0599/>`_. (`7102 <https://github.com/pypa/pip/issues/7102>`_) Bug Fixes --------- - Abort installation if any archive contains a file which would be placed outside the extraction location. (`3907 <https://github.com/pypa/pip/issues/3907>`_) - pip's CLI completion code no longer prints a Traceback if it is interrupted. (`3942 <https://github.com/pypa/pip/issues/3942>`_) - Correct inconsistency related to the ``hg+file`` scheme.
