Deprecations and Removals
-------------------------

- Removed the deprecated ``--egg`` parameter to ``pip install``. (1749)
- Removed support for uninstalling projects which have been installed using
distutils. distutils installed projects do not include metadata indicating
what files belong to that install and thus it is impossible to *actually*
uninstall them rather than just remove the metadata saying they've been
installed while leaving all of the actual files behind. (2386)
- Removed the deprecated ``--download`` option to ``pip install``. (2643)
- Removed the deprecated --(no-)use-wheel flags to ``pip install`` and ``pip
wheel``. (2699)
- Removed the deprecated ``--allow-external``, ``--allow-all-external``, and
``--allow-unverified`` options. (3070)
- Switch the default for ``pip list`` to the columns format, and deprecate the
legacy format. (3654, 3686)
- Deprecate support for Python 3.3. (3796)
- Removed the deprecated ``--default-vcs`` option. (4052)
- Removed the ``setup.py test`` support from our sdist as it wasn't being
maintained as a supported means to run our tests. (4203)
- Dropped support for Python 2.6. (4343)
- Removed the --editable flag from pip download, as it did not make sense
(4362)
- Deprecate SVN detection based on dependency links in ``pip freeze``. (4449)
- Move all of pip's APIs into the pip._internal package, properly reflecting
the fact that pip does not currently have any public APIs. (4696, 4700)

Features
--------

- Add `--progress-bar <progress_bar>` to ``pip download``, ``pip install`` and
``pip wheel`` commands, to allow selecting a specific progress indicator or,
to completely suppress, (for example in a CI environment) use
``--progress-bar off. (2369, 2756)
- Add `--no-color` to `pip`. All colored output is disabled if this flag is
detected. (2449)
- pip uninstall now ignores the absence of a requirement and prints a warning.
(3016, 4642)
- Improved the memory and disk efficiency of the HTTP cache. (3515)
- Support for packages specifying build dependencies in pyproject.toml (see
`PEP 518 <https://www.python.org/dev/peps/pep-0518/>`__). Packages which
specify one or more build dependencies this way will be built into wheels in
an isolated environment with those dependencies installed. (3691)
- pip now supports environment variable expansion in requirement files using
only ``${VARIABLE}`` syntax on all platforms. (3728)
- Allowed combinations of -q and -v to act sanely. Then we don't need warnings
mentioned in the issue. (4008)
- Add `--exclude-editable` to ``pip freeze`` and ``pip list`` to exclude
editable packages from installed package list. (4015, 4016)
- Improve the error message for the common ``pip install ./requirements.txt``
case. (4127)
- Add support for the new `` url`` syntax from PEP 508. (4175)
- Add setuptools version to the statistics sent to BigQuery. (4209)
- Report the line which caused the hash error when using requirement files.
(4227)
- Add a pip config command for managing configuration files. (4240)
- Allow ``pip download`` to be used with a specific platform when ``--no-deps``
is set. (4289)
- Support build-numbers in wheel versions and support sorting with
build-numbers. (4299)
- Change pip outdated to use PackageFinder in order to do the version lookup so
that local mirrors in Environments that do not have Internet connections can
be used as the Source of Truth for latest version. (4336)
- pip now retries on more HTTP status codes, for intermittent failures.
Previously, it only retried on the standard 503. Now, it also retries on 500
(transient failures on AWS S3), 520 and 527 (transient failures on
Cloudflare). (4473)
- pip now displays where it is looking for packages, if non-default locations
are used. (4483)
- Display a message to run the right command for modifying pip on Windows
(4490)
- Add Man Pages for pip (4491)
- Make uninstall command less verbose by default (4493)
- Switch the default upgrade strategy to be 'only-if-needed' (4500)
- Installing from a local directory or a VCS URL now builds a wheel to install,
rather than running ``setup.py install``. Wheels from these sources are not
cached. (4501)
- Don't log a warning when installing a dependency from Git if the name looks
like a commit hash. (4507)
- pip now displays a warning when it installs scripts from a wheel outside the
PATH. These warnings can be suppressed using a new --no-warn-script-location
option. (4553)
- Local Packages can now be referenced using forward slashes on Windows.
(4563)
- pip show learnt a new Required-by field that lists currently installed
packages that depend on the shown package (4564)
- The command-line autocompletion engine ``pip show`` now autocompletes
installed distribution names. (4749)
- Change documentation theme to be in line with Python Documentation (4758)
- Add auto completion of short options. (4954)
- Run 'setup.py develop' inside pep518 build environment. (4999)
- pip install now prints an error message when it installs an incompatible
version of a dependency. (5000)
- Added a way to distinguish between pip installed packages and those from the
system package manager in 'pip list'. Specifically, 'pip list -v' also shows
the installer of package if it has that meta data. (949)
- Show install locations when list command ran with "-v" option. (979)

Bug Fixes
---------

- Allow pip to work if the ``GIT_DIR`` and ``GIT_WORK_TREE`` environment
variables are set. (1130)
- Make ``pip install --force-reinstall`` not require passing ``--upgrade``.
(1139)
- Return a failing exit status when `pip install`, `pip download`, or `pip
wheel` is called with no requirements. (2720)
- Interactive setup.py files will no longer hang indefinitely. (2732, 4982)
- Correctly reset the terminal if an exception occurs while a progress bar is
being shown. (3015)
- "Support URL-encoded characters in URL credentials." (3236)
- Don't assume sys.__stderr__.encoding exists (3356)
- Fix ``pip uninstall`` when ``easy-install.pth`` lacks a trailing newline.
(3741)
- Keep install options in requirements.txt from leaking. (3763)
- pip no longer passes global options from one package to later packages in the
same requirement file. (3830)
- Support installing from Git refs (3876)
- Use pkg_resources to parse the entry points file to allow names with colons.
(3901)
- ``-q`` specified once correctly sets logging level to WARNING, instead of
CRITICAL. Use `-qqq` to have the previous behavior back. (3994)
- Shell completion scripts now use correct executable names (e.g., ``pip3``
instead of ``pip``) (3997)
- Changed vendored encodings from ``utf8`` to ``utf-8``. (4076)
- Fixes destination directory of data_files when ``pip install --target`` is
used. (4092)
- Limit the disabling of requests' pyopenssl to Windows only. Fixes
"SNIMissingWarning / InsecurePlatformWarning not fixable with pip 9.0 /
9.0.1" (for non-Windows) (4098)
- Support the installation of wheels with non-PEP 440 version in their
filenames. (4169)
- Fall back to sys.getdefaultencoding() if locale.getpreferredencoding()
returns None in `pip.utils.encoding.auto_decode`. (4184)
- Fix a bug where `SETUPTOOLS_SHIM` got called incorrectly for relative path
requirements by converting relative paths to absolute paths prior to calling
the shim. (4208)
- Return the latest version number in search results. (4219)
- Improve error message on permission errors (4233)
- Fail gracefully when ``/etc/image_version`` (or another distro version file)
appears to exists but is not readable. (4249)
- Avoid importing setuptools in the parent pip process, to avoid a race
condition when upgrading one of setuptools dependencies. (4264)
- Fix for an incorrect ``freeze`` warning message due to a package being
included in multiple requirements files that were passed to ``freeze``.
Instead of warning incorrectly that the package is not installed, pip now
warns that the package was declared multiple times and lists the name of each
requirements file that contains the package in question. (4293)
- Generalize help text for ``compile``/``no-compile`` flags. (4316)
- Handle the case when ``/etc`` is not readable by the current user by using a
hardcoded list of possible names of release files. (4320)
- Fixed a ``NameError`` when attempting to catch ``FileNotFoundError`` on
Python 2.7. (4322)
- Ensure USER_SITE is correctly initialised. (4437)
- Reinstalling an editable package from Git no longer assumes that the
``master`` branch exists. (4448)
- This fixes an issue where when someone who tries to use git with pip but pip
can't because git is not in the path environment variable. This clarifies the
error given to suggest to the user what might be wrong. (4461)
- Improve handling of text output from build tools (avoid Unicode errors)
(4486)
- Fix a "No such file or directory" error when using --prefix. (4495)
- Allow commands to opt out of --require-venv. This allows pip help to work
even when the environment variable PIP_REQUIRE_VIRTUALENV is set. (4496)
- Fix warning message on mismatched versions during installation. (4655)
- pip now records installed files in a deterministic manner improving
reproducibility. (4667)
- Fix an issue where ``pip install -e`` on a Git url would fail to update if a
branch or tag name is specified that happens to match the prefix of the
current ``HEAD`` commit hash. (4675)
- Fix an issue where a variable assigned in a try clause was accessed in the
except clause, resulting in an undefined variable error in the except clause.
(4811)
- Use log level `info` instead of `warning` when ignoring packages due to
environment markers. (4876)
- Replaced typo mistake in subversion support. (4908)
- Terminal size is now correctly inferred when using Python 3 on Windows.
(4966)
- Abort if reading configuration causes encoding errors. (4976)
