Changelog
### 23.3.1
```
===================
Bug Fixes
---------
- Handle a timezone indicator of Z when parsing dates in the self check. (`12338 <https://github.com/pypa/pip/issues/12338>`_)
- Fix bug where installing the same package at the same time with multiple pip processes could fail. (`12361 <https://github.com/pypa/pip/issues/12361>`_)
```
### 23.3
```
=================
Process
-------
- Added reference to `vulnerability reporting guidelines <https://www.python.org/dev/security/>`_ to pip's security policy.
Deprecations and Removals
-------------------------
- Drop a fallback to using SecureTransport on macOS. It was useful when pip detected OpenSSL older than 1.0.1, but the current pip does not support any Python version supporting such old OpenSSL versions. (`12175 <https://github.com/pypa/pip/issues/12175>`_)
Features
--------
- Improve extras resolution for multiple constraints on same base package. (`11924 <https://github.com/pypa/pip/issues/11924>`_)
- Improve use of datastructures to make candidate selection 1.6x faster. (`12204 <https://github.com/pypa/pip/issues/12204>`_)
- Allow ``pip install --dry-run`` to use platform and ABI overriding options. (`12215 <https://github.com/pypa/pip/issues/12215>`_)
- Add ``is_yanked`` boolean entry to the installation report (``--report``) to indicate whether the requirement was yanked from the index, but was still selected by pip conform to :pep:`592`. (`12224 <https://github.com/pypa/pip/issues/12224>`_)
Bug Fixes
---------
- Ignore errors in temporary directory cleanup (show a warning instead). (`11394 <https://github.com/pypa/pip/issues/11394>`_)
- Normalize extras according to :pep:`685` from package metadata in the resolver
for comparison. This ensures extras are correctly compared and merged as long
as the package providing the extra(s) is built with values normalized according
to the standard. Note, however, that this *does not* solve cases where the
package itself contains unnormalized extra values in the metadata. (`11649 <https://github.com/pypa/pip/issues/11649>`_)
- Prevent downloading sdists twice when :pep:`658` metadata is present. (`11847 <https://github.com/pypa/pip/issues/11847>`_)
- Include all requested extras in the install report (``--report``). (`11924 <https://github.com/pypa/pip/issues/11924>`_)
- Removed uses of ``datetime.datetime.utcnow`` from non-vendored code. (`12005 <https://github.com/pypa/pip/issues/12005>`_)
- Consistently report whether a dependency comes from an extra. (`12095 <https://github.com/pypa/pip/issues/12095>`_)
- Fix completion script for zsh (`12166 <https://github.com/pypa/pip/issues/12166>`_)
- Fix improper handling of the new onexc argument of ``shutil.rmtree()`` in Python 3.12. (`12187 <https://github.com/pypa/pip/issues/12187>`_)
- Filter out yanked links from the available versions error message: "(from versions: 1.0, 2.0, 3.0)" will not contain yanked versions conform PEP 592. The yanked versions (if any) will be mentioned in a separate error message. (`12225 <https://github.com/pypa/pip/issues/12225>`_)
- Fix crash when the git version number contains something else than digits and dots. (`12280 <https://github.com/pypa/pip/issues/12280>`_)
- Use ``-r=...`` instead of ``-r ...`` to specify references with Mercurial. (`12306 <https://github.com/pypa/pip/issues/12306>`_)
- Redact password from URLs in some additional places. (`12350 <https://github.com/pypa/pip/issues/12350>`_)
- pip uses less memory when caching large packages. As a result, there is a new on-disk cache format stored in a new directory ($PIP_CACHE_DIR/http-v2). (`2984 <https://github.com/pypa/pip/issues/2984>`_)
Vendored Libraries
------------------
- Upgrade certifi to 2023.7.22
- Add truststore 0.8.0
- Upgrade urllib3 to 1.26.17
Improved Documentation
----------------------
- Document that ``pip search`` support has been removed from PyPI (`12059 <https://github.com/pypa/pip/issues/12059>`_)
- Clarify --prefer-binary in CLI and docs (`12122 <https://github.com/pypa/pip/issues/12122>`_)
- Document that using OS-provided Python can cause pip's test suite to report false failures. (`12334 <https://github.com/pypa/pip/issues/12334>`_)
```
### 23.2.1
```
===================
Bug Fixes
---------
- Disable :pep:`658` metadata fetching with the legacy resolver. (`12156 <https://github.com/pypa/pip/issues/12156>`_)
```
### 23.2
```
=================
Process
-------
- Deprecate support for eggs for Python 3.11 or later, when the new ``importlib.metadata`` backend is used to load distribution metadata. This only affects the egg *distribution format* (with the ``.egg`` extension); distributions using the ``.egg-info`` *metadata format* (but are not actually eggs) are not affected. For more information about eggs, see `relevant section in the setuptools documentation <https://setuptools.pypa.io/en/stable/deprecated/python_eggs.html>`__.
Deprecations and Removals
-------------------------
- Deprecate legacy version and version specifiers that don't conform to `PEP 440
<https://peps.python.org/pep-0440/>`_ (`#12063 <https://github.com/pypa/pip/issues/12063>`_)
- ``freeze`` no longer excludes the ``setuptools``, ``distribute``, and ``wheel``
from the output when running on Python 3.12 or later, where they are not
included in a virtual environment by default. Use ``--exclude`` if you wish to
exclude any of these packages. (`4256 <https://github.com/pypa/pip/issues/4256>`_)
Features
--------
- make rejection messages slightly different between 1 and 8, so the user can make the difference. (`12040 <https://github.com/pypa/pip/issues/12040>`_)
Bug Fixes
---------
- Fix ``pip completion --zsh``. (`11417 <https://github.com/pypa/pip/issues/11417>`_)
- Prevent downloading files twice when :pep:`658` metadata is present (`11847 <https://github.com/pypa/pip/issues/11847>`_)
- Add permission check before configuration (`11920 <https://github.com/pypa/pip/issues/11920>`_)
- Fix deprecation warnings in Python 3.12 for usage of shutil.rmtree (`11957 <https://github.com/pypa/pip/issues/11957>`_)
- Ignore invalid or unreadable ``origin.json`` files in the cache of locally built wheels. (`11985 <https://github.com/pypa/pip/issues/11985>`_)
- Fix installation of packages with :pep:`658` metadata using non-canonicalized names (`12038 <https://github.com/pypa/pip/issues/12038>`_)
- Correctly parse ``dist-info-metadata`` values from JSON-format index data. (`12042 <https://github.com/pypa/pip/issues/12042>`_)
- Fail with an error if the ``--python`` option is specified after the subcommand name. (`12067 <https://github.com/pypa/pip/issues/12067>`_)
- Fix slowness when using ``importlib.metadata`` (the default way for pip to read metadata in Python 3.11+) and there is a large overlap between already installed and to-be-installed packages. (`12079 <https://github.com/pypa/pip/issues/12079>`_)
- Pass the ``-r`` flag to mercurial to be explicit that a revision is passed and protect
against ``hg`` options injection as part of VCS URLs. Users that do not have control on
VCS URLs passed to pip are advised to upgrade. (`12119 <https://github.com/pypa/pip/issues/12119>`_)

### 23.1.2
```
===================
Vendored Libraries
------------------
- Upgrade setuptools to 67.7.2
```
### 23.1.1
```
===================
Bug Fixes
---------
- Revert `11487 <https://github.com/pypa/pip/pull/11487>`_, as it causes issues with virtualenvs created by the Windows Store distribution of Python. (`#11987 <https://github.com/pypa/pip/issues/11987>`_)
Vendored Libraries
------------------
- Revert pkg_resources (via setuptools) back to 65.6.3
Improved Documentation
----------------------
- Update documentation to reflect the new behavior of using the cache of locally
built wheels in hash-checking mode. (`11967 <https://github.com/pypa/pip/issues/11967>`_)
```
### 23.1
```
=================
Deprecations and Removals
-------------------------
- Remove support for the deprecated ``--install-options``. (`11358 <https://github.com/pypa/pip/issues/11358>`_)
- ``--no-binary`` does not imply ``setup.py install`` anymore. Instead a wheel will be
built locally and installed. (`11451 <https://github.com/pypa/pip/issues/11451>`_)
- ``--no-binary`` does not disable the cache of locally built wheels anymore. It only
means "don't download wheels". (`11453 <https://github.com/pypa/pip/issues/11453>`_)
- Deprecate ``--build-option`` and ``--global-option``. Users are invited to switch to
``--config-settings``. (`11859 <https://github.com/pypa/pip/issues/11859>`_)
- Using ``--config-settings`` with projects that don't have a ``pyproject.toml`` now prints
a deprecation warning. In the future the presence of config settings will automatically
enable the default build backend for legacy projects and pass the settings to it. (`11915 <https://github.com/pypa/pip/issues/11915>`_)
- Remove ``setup.py install`` fallback when building a wheel failed for projects without
``pyproject.toml``. (`8368 <https://github.com/pypa/pip/issues/8368>`_)
- When the ``wheel`` package is not installed, pip now uses the default build backend
instead of ``setup.py install`` and ``setup.py develop`` for project without
``pyproject.toml``. (`8559 <https://github.com/pypa/pip/issues/8559>`_)
Features
--------
- Specify egg-link location in assertion message when it does not match installed location to provide better error message for debugging. (`10476 <https://github.com/pypa/pip/issues/10476>`_)
- Present conflict information during installation after each choice that is rejected (pass ``-vv`` to ``pip install`` to show it) (`10937 <https://github.com/pypa/pip/issues/10937>`_)
- Display dependency chain on each Collecting/Processing log line. (`11169 <https://github.com/pypa/pip/issues/11169>`_)
- Support a per-requirement ``--config-settings`` option in requirements files. (`11325 <https://github.com/pypa/pip/issues/11325>`_)
- The ``--config-settings``/``-C`` option now supports using the same key multiple
times. When the same key is specified multiple times, all values are passed to
the build backend as a list, as opposed to the previous behavior, where pip would
only pass the last value if the same key was used multiple times. (`11681 <https://github.com/pypa/pip/issues/11681>`_)
- Add ``-C`` as a short version of the ``--config-settings`` option. (`11786 <https://github.com/pypa/pip/issues/11786>`_)
- Reduce the number of resolver rounds, since backjumping makes the resolver more efficient in finding solutions. This also makes pathological cases fail quicker. (`11908 <https://github.com/pypa/pip/issues/11908>`_)
- Warn if ``--hash`` is used on a line without requirement in a requirements file. (`11935 <https://github.com/pypa/pip/issues/11935>`_)
- Stop propagating CLI ``--config-settings`` to the build dependencies. They already did
not propagate to requirements provided in requirement files. To pass the same config
settings to several requirements, users should provide the requirements as CLI
arguments. (`11941 <https://github.com/pypa/pip/issues/11941>`_)
- Support wheel cache when using ``--require-hashes``. (`5037 <https://github.com/pypa/pip/issues/5037>`_)
- Add ``--keyring-provider`` flag. See the Authentication page in the documentation for more info. (`8719 <https://github.com/pypa/pip/issues/8719>`_)
- In the case of virtual environments, configuration files are now also included from the base installation. (`9752 <https://github.com/pypa/pip/issues/9752>`_)
Bug Fixes
---------
- Fix grammar by changing "A new release of pip available:" to "A new release of pip is available:" in the notice used for indicating that. (`11529 <https://github.com/pypa/pip/issues/11529>`_)
- Normalize paths before checking if installed scripts are on PATH. (`11719 <https://github.com/pypa/pip/issues/11719>`_)
- Correct the way to decide if keyring is available. (`11774 <https://github.com/pypa/pip/issues/11774>`_)
- More consistent resolution backtracking by removing legacy hack related to setuptools resolution (`11837 <https://github.com/pypa/pip/issues/11837>`_)
- Include ``AUTHORS.txt`` in pip's wheels. (`11882 <https://github.com/pypa/pip/issues/11882>`_)
- The ``uninstall`` and ``install --force-reinstall`` commands no longer call
``normalize_path()`` repeatedly on the same paths. Instead, these results are
cached for the duration of an uninstall operation, resulting in improved
performance, particularly on Windows. (`11889 <https://github.com/pypa/pip/issues/11889>`_)
- Fix and improve the parsing of hashes embedded in URL fragments. (`11936 <https://github.com/pypa/pip/issues/11936>`_)
- When package A depends on package B provided as a direct URL dependency including a hash
embedded in the link, the ``--require-hashes`` option did not warn when user supplied hashes
were missing for package B. (`11938 <https://github.com/pypa/pip/issues/11938>`_)
- Correctly report ``requested_extras`` in the installation report when extras are
specified for a local directory installation. (`11946 <https://github.com/pypa/pip/issues/11946>`_)
- When installing an archive from a direct URL or local file, populate
``download_info.info.hashes`` in the installation report, in addition to the legacy
``download_info.info.hash`` key. (`11948 <https://github.com/pypa/pip/issues/11948>`_)

- Add SECURITY.md to make the policy offical. (`11809 <https://github.com/pypa/pip/issues/11809>`_)
- Add username to Git over SSH example. (`11838 <https://github.com/pypa/pip/issues/11838>`_)
- Quote extras in the pip install docs to guard shells with default glob
qualifiers, like zsh. (`11842 <https://github.com/pypa/pip/issues/11842>`_)

```
### 23.0.1
```
===================
Features
--------
- Ignore PIP_REQUIRE_VIRTUALENV for ``pip index`` (`11671 <https://github.com/pypa/pip/issues/11671>`_)
- Implement ``--break-system-packages`` to permit installing packages into
``EXTERNALLY-MANAGED`` Python installations. (`11780 <https://github.com/pypa/pip/issues/11780>`_)
Bug Fixes
---------
- Improve handling of isolated build environments on platforms that
customize the Python's installation schemes, such as Debian and
Homebrew. (`11740 <https://github.com/pypa/pip/issues/11740>`_)
- Do not crash in presence of misformatted hash field in ``direct_url.json``. (`11773 <https://github.com/pypa/pip/issues/11773>`_)
```
### 23.0
```
=================
Features
--------
- Change the hashes in the installation report to be a mapping. Emit the
``archive_info.hashes`` dictionary in ``direct_url.json``. (`11312 <https://github.com/pypa/pip/issues/11312>`_)
- Implement logic to read the ``EXTERNALLY-MANAGED`` file as specified in :pep:`668`.
This allows a downstream Python distributor to prevent users from using pip to
modify the externally managed environment. (`11381 <https://github.com/pypa/pip/issues/11381>`_)
- Enable the use of ``keyring`` found on ``PATH``. This allows ``keyring``
installed using ``pipx`` to be used by ``pip``. (`11589 <https://github.com/pypa/pip/issues/11589>`_)
- The inspect and installation report formats are now declared stable, and their version
has been bumped from ``0`` to ``1``. (`11757 <https://github.com/pypa/pip/issues/11757>`_)
Bug Fixes
---------
- Wheel cache behavior is restored to match previous versions, allowing the
cache to find existing entries. (`11527 <https://github.com/pypa/pip/issues/11527>`_)
- Use the "venv" scheme if available to obtain prefixed lib paths. (`11598 <https://github.com/pypa/pip/issues/11598>`_)
- Deprecated a historical ambiguity in how ``egg`` fragments in URL-style
requirements are formatted and handled. ``egg`` fragments that do not look
like :pep:`508` names now produce a deprecation warning. (`11617 <https://github.com/pypa/pip/issues/11617>`_)
- Fix scripts path in isolated build environment on Debian. (`11623 <https://github.com/pypa/pip/issues/11623>`_)
- Make ``pip show`` show the editable location if package is editable (`11638 <https://github.com/pypa/pip/issues/11638>`_)
- Stop checking that ``wheel`` is present when ``build-system.requires``
is provided without ``build-system.build-backend`` as ``setuptools``
(which we still check for) will inject it anyway. (`11673 <https://github.com/pypa/pip/issues/11673>`_)
- Fix an issue when an already existing in-memory distribution would cause
exceptions in ``pip install`` (`11704 <https://github.com/pypa/pip/issues/11704>`_)

- Remove mention that editable installs are necessary for pip freeze to report the VCS
URL. (`11675 <https://github.com/pypa/pip/issues/11675>`_)
- Clarify that the egg URL fragment is only necessary for editable VCS installs, and
otherwise not necessary anymore. (`11676 <https://github.com/pypa/pip/issues/11676>`_)
```
### 22.3.1
```
===================
Bug Fixes
---------
- Fix entry point generation of ``pip.X``, ``pipX.Y``, and ``easy_install-X.Y``
to correctly account for multi-digit Python version segments (e.g. the "11"
part of 3.11). (`11547 <https://github.com/pypa/pip/issues/11547>`_)
```
### 22.3
```
=================
Deprecations and Removals
-------------------------
- Deprecate ``--install-options`` which forces pip to use the deprecated ``install``
command of ``setuptools``. (`11358 <https://github.com/pypa/pip/issues/11358>`_)
- Deprecate installation with 'setup.py install' when no-binary is enabled for
source distributions without 'pyproject.toml'. (`11452 <https://github.com/pypa/pip/issues/11452>`_)
- Deprecate --no-binary`` disabling the wheel cache. (`11454 <https://github.com/pypa/pip/issues/11454>`_)
- Remove ``--use-feature=2020-resolver`` opt-in flag. This was supposed to be removed in 21.0, but missed during that release cycle. (`11493 <https://github.com/pypa/pip/issues/11493>`_)
- Deprecate installation with 'setup.py install' when the 'wheel' package is absent for
source distributions without 'pyproject.toml'. (`8559 <https://github.com/pypa/pip/issues/8559>`_)
- Remove the ability to use ``pip list --outdated`` in combination with ``--format=freeze``. (`9789 <https://github.com/pypa/pip/issues/9789>`_)
Features
--------
- Use ``shell=True`` for opening the editor with ``pip config edit``. (`10716 <https://github.com/pypa/pip/issues/10716>`_)
- Use the ``data-dist-info-metadata`` attribute from :pep:`658` to resolve distribution metadata without downloading the dist yet. (`11111 <https://github.com/pypa/pip/issues/11111>`_)
- Add an option to run the test suite with pip built as a zipapp. (`11250 <https://github.com/pypa/pip/issues/11250>`_)
- Add a ``--python`` option to allow pip to manage Python environments other
than the one pip is installed in. (`11320 <https://github.com/pypa/pip/issues/11320>`_)
- Document the new (experimental) zipapp distribution of pip. (`11459 <https://github.com/pypa/pip/issues/11459>`_)
- Use the much faster 'bzr co --lightweight' to obtain a copy of a Bazaar tree. (`5444 <https://github.com/pypa/pip/issues/5444>`_)
Bug Fixes
---------
- Fix ``--no-index`` when ``--index-url`` or ``--extra-index-url`` is specified
inside a requirements file. (`11276 <https://github.com/pypa/pip/issues/11276>`_)
- Ensure that the candidate ``pip`` executable exists, when checking for a new version of pip. (`11309 <https://github.com/pypa/pip/issues/11309>`_)
- Ignore distributions with invalid ``Name`` in metadata instead of crashing, when
using the ``importlib.metadata`` backend. (`11352 <https://github.com/pypa/pip/issues/11352>`_)
- Raise RequirementsFileParseError when parsing malformed requirements options that can't be successfully parsed by shlex. (`11491 <https://github.com/pypa/pip/issues/11491>`_)
- Fix build environment isolation on some system Pythons. (`6264 <https://github.com/pypa/pip/issues/6264>`_)

```
### 22.2.2
```
===================
Bug Fixes
---------
- Avoid ``AttributeError`` when removing the setuptools-provided ``_distutils_hack`` and it is missing its implementation. (`11314 <https://github.com/pypa/pip/issues/11314>`_)
- Fix import error when reinstalling pip in user site. (`11319 <https://github.com/pypa/pip/issues/11319>`_)
- Show pip deprecation warnings by default. (`11330 <https://github.com/pypa/pip/issues/11330>`_)
```
### 22.2.1
```
===================
Bug Fixes
---------
- Send the pip upgrade prompt to stderr. (`11282 <https://github.com/pypa/pip/issues/11282>`_)
- Ensure that things work correctly in environments where setuptools-injected
``distutils`` is available by default. This is done by cooperating with
setuptools' injection logic to ensure that pip uses the ``distutils`` from the
Python standard library instead. (`11298 <https://github.com/pypa/pip/issues/11298>`_)
- Clarify that ``pip cache``'s wheels-related output is about locally built wheels only. (`11300 <https://github.com/pypa/pip/issues/11300>`_)
```
### 22.2
```
=================
Deprecations and Removals
-------------------------
- Remove the ``html5lib`` deprecated feature flag. (`10825 <https://github.com/pypa/pip/issues/10825>`_)
- Remove ``--use-deprecated=backtrack-on-build-failures``. (`11241 <https://github.com/pypa/pip/issues/11241>`_)
Features
--------
- Add support to use `truststore <https://pypi.org/project/truststore/>`_ as an
alternative SSL certificate verification backend. The backend can be enabled on Python
3.10 and later by installing ``truststore`` into the environment, and adding the
``--use-feature=truststore`` flag to various pip commands.
``truststore`` differs from the current default verification backend (provided by
``certifi``) in it uses the operating system’s trust store, which can be better
controlled and augmented to better support non-standard certificates. Depending on
feedback, pip may switch to this as the default certificate verification backend in
the future. (`11082 <https://github.com/pypa/pip/issues/11082>`_)
- Add ``--dry-run`` option to ``pip install``, to let it print what it would install but
not actually change anything in the target environment. (`11096 <https://github.com/pypa/pip/issues/11096>`_)
- Record in wheel cache entries the URL of the original artifact that was downloaded
to build the cached wheels. The record is named ``origin.json`` and uses the PEP 610
Direct URL format. (`11137 <https://github.com/pypa/pip/issues/11137>`_)
- Support `PEP 691 <https://peps.python.org/pep-0691/>`_. (`#11158 <https://github.com/pypa/pip/issues/11158>`_)
- pip's deprecation warnings now subclass the built-in ``DeprecationWarning``, and
can be suppressed by running the Python interpreter with
``-W ignore::DeprecationWarning``. (`11225 <https://github.com/pypa/pip/issues/11225>`_)
- Add ``pip inspect`` command to obtain the list of installed distributions and other
information about the Python environment, in JSON format. (`11245 <https://github.com/pypa/pip/issues/11245>`_)
- Significantly speed up isolated environment creation, by using the same
sources for pip instead of creating a standalone installation for each
environment. (`11257 <https://github.com/pypa/pip/issues/11257>`_)
- Add an experimental ``--report`` option to the install command to generate a JSON report
of what was installed. In combination with ``--dry-run`` and ``--ignore-installed`` it
can be used to resolve the requirements. (`53 <https://github.com/pypa/pip/issues/53>`_)
Bug Fixes
---------
- Fix ``pip install --pre`` for packages with pre-release build dependencies defined
both in ``pyproject.toml``'s ``build-system.requires`` and ``setup.py``'s
``setup_requires``. (`10222 <https://github.com/pypa/pip/issues/10222>`_)
- When pip rewrites the shebang line in a script during wheel installation,
update the hash and size in the corresponding ``RECORD`` file entry. (`10744 <https://github.com/pypa/pip/issues/10744>`_)
- Do not consider a ``.dist-info`` directory found inside a wheel-like zip file
as metadata for an installed distribution. A package in a wheel is (by
definition) not installed, and is not guaranteed to work due to how a wheel is
structured. (`11217 <https://github.com/pypa/pip/issues/11217>`_)
- Use ``importlib.resources`` to read the ``vendor.txt`` file in ``pip debug``.
This makes the command safe for use from a zipapp. (`11248 <https://github.com/pypa/pip/issues/11248>`_)
- Make the ``--use-pep517`` option of the ``download`` command apply not just
to the requirements specified on the command line, but to their dependencies,
as well. (`9523 <https://github.com/pypa/pip/issues/9523>`_)

Changelog
### 23.3.1 ``` =================== Bug Fixes --------- - Handle a timezone indicator of Z when parsing dates in the self check. (`12338 <https://github.com/pypa/pip/issues/12338>`_) - Fix bug where installing the same package at the same time with multiple pip processes could fail. (`12361 <https://github.com/pypa/pip/issues/12361>`_) ``` ### 23.3 ``` ================= Process ------- - Added reference to `vulnerability reporting guidelines <https://www.python.org/dev/security/>`_ to pip's security policy. Deprecations and Removals ------------------------- - Drop a fallback to using SecureTransport on macOS. It was useful when pip detected OpenSSL older than 1.0.1, but the current pip does not support any Python version supporting such old OpenSSL versions. (`12175 <https://github.com/pypa/pip/issues/12175>`_) Features -------- - Improve extras resolution for multiple constraints on same base package. (`11924 <https://github.com/pypa/pip/issues/11924>`_) - Improve use of datastructures to make candidate selection 1.6x faster. (`12204 <https://github.com/pypa/pip/issues/12204>`_) - Allow ``pip install --dry-run`` to use platform and ABI overriding options. (`12215 <https://github.com/pypa/pip/issues/12215>`_) - Add ``is_yanked`` boolean entry to the installation report (``--report``) to indicate whether the requirement was yanked from the index, but was still selected by pip conform to :pep:`592`. (`12224 <https://github.com/pypa/pip/issues/12224>`_) Bug Fixes --------- - Ignore errors in temporary directory cleanup (show a warning instead). (`11394 <https://github.com/pypa/pip/issues/11394>`_) - Normalize extras according to :pep:`685` from package metadata in the resolver for comparison. This ensures extras are correctly compared and merged as long as the package providing the extra(s) is built with values normalized according to the standard. Note, however, that this *does not* solve cases where the package itself contains unnormalized extra values in the metadata. (`11649 <https://github.com/pypa/pip/issues/11649>`_) - Prevent downloading sdists twice when :pep:`658` metadata is present. (`11847 <https://github.com/pypa/pip/issues/11847>`_) - Include all requested extras in the install report (``--report``). (`11924 <https://github.com/pypa/pip/issues/11924>`_) - Removed uses of ``datetime.datetime.utcnow`` from non-vendored code. (`12005 <https://github.com/pypa/pip/issues/12005>`_) - Consistently report whether a dependency comes from an extra. (`12095 <https://github.com/pypa/pip/issues/12095>`_) - Fix completion script for zsh (`12166 <https://github.com/pypa/pip/issues/12166>`_) - Fix improper handling of the new onexc argument of ``shutil.rmtree()`` in Python 3.12. (`12187 <https://github.com/pypa/pip/issues/12187>`_) - Filter out yanked links from the available versions error message: "(from versions: 1.0, 2.0, 3.0)" will not contain yanked versions conform PEP 592. The yanked versions (if any) will be mentioned in a separate error message. (`12225 <https://github.com/pypa/pip/issues/12225>`_) - Fix crash when the git version number contains something else than digits and dots. (`12280 <https://github.com/pypa/pip/issues/12280>`_) - Use ``-r=...`` instead of ``-r ...`` to specify references with Mercurial. (`12306 <https://github.com/pypa/pip/issues/12306>`_) - Redact password from URLs in some additional places. (`12350 <https://github.com/pypa/pip/issues/12350>`_) - pip uses less memory when caching large packages. As a result, there is a new on-disk cache format stored in a new directory ($PIP_CACHE_DIR/http-v2). (`2984 <https://github.com/pypa/pip/issues/2984>`_) Vendored Libraries ------------------ - Upgrade certifi to 2023.7.22 - Add truststore 0.8.0 - Upgrade urllib3 to 1.26.17 Improved Documentation ---------------------- - Document that ``pip search`` support has been removed from PyPI (`12059 <https://github.com/pypa/pip/issues/12059>`_) - Clarify --prefer-binary in CLI and docs (`12122 <https://github.com/pypa/pip/issues/12122>`_) - Document that using OS-provided Python can cause pip's test suite to report false failures. (`12334 <https://github.com/pypa/pip/issues/12334>`_) ``` ### 23.2.1 ``` =================== Bug Fixes --------- - Disable :pep:`658` metadata fetching with the legacy resolver. (`12156 <https://github.com/pypa/pip/issues/12156>`_) ``` ### 23.2 ``` ================= Process ------- - Deprecate support for eggs for Python 3.11 or later, when the new ``importlib.metadata`` backend is used to load distribution metadata. This only affects the egg *distribution format* (with the ``.egg`` extension); distributions using the ``.egg-info`` *metadata format* (but are not actually eggs) are not affected. For more information about eggs, see `relevant section in the setuptools documentation <https://setuptools.pypa.io/en/stable/deprecated/python_eggs.html>`__. Deprecations and Removals ------------------------- - Deprecate legacy version and version specifiers that don't conform to `PEP 440 <https://peps.python.org/pep-0440/>`_ (`#12063 <https://github.com/pypa/pip/issues/12063>`_) - ``freeze`` no longer excludes the ``setuptools``, ``distribute``, and ``wheel`` from the output when running on Python 3.12 or later, where they are not included in a virtual environment by default. Use ``--exclude`` if you wish to exclude any of these packages. (`4256 <https://github.com/pypa/pip/issues/4256>`_) Features -------- - make rejection messages slightly different between 1 and 8, so the user can make the difference. (`12040 <https://github.com/pypa/pip/issues/12040>`_) Bug Fixes --------- - Fix ``pip completion --zsh``. (`11417 <https://github.com/pypa/pip/issues/11417>`_) - Prevent downloading files twice when :pep:`658` metadata is present (`11847 <https://github.com/pypa/pip/issues/11847>`_) - Add permission check before configuration (`11920 <https://github.com/pypa/pip/issues/11920>`_) - Fix deprecation warnings in Python 3.12 for usage of shutil.rmtree (`11957 <https://github.com/pypa/pip/issues/11957>`_) - Ignore invalid or unreadable ``origin.json`` files in the cache of locally built wheels. (`11985 <https://github.com/pypa/pip/issues/11985>`_) - Fix installation of packages with :pep:`658` metadata using non-canonicalized names (`12038 <https://github.com/pypa/pip/issues/12038>`_) - Correctly parse ``dist-info-metadata`` values from JSON-format index data. (`12042 <https://github.com/pypa/pip/issues/12042>`_) - Fail with an error if the ``--python`` option is specified after the subcommand name. (`12067 <https://github.com/pypa/pip/issues/12067>`_) - Fix slowness when using ``importlib.metadata`` (the default way for pip to read metadata in Python 3.11+) and there is a large overlap between already installed and to-be-installed packages. (`12079 <https://github.com/pypa/pip/issues/12079>`_) - Pass the ``-r`` flag to mercurial to be explicit that a revision is passed and protect against ``hg`` options injection as part of VCS URLs. Users that do not have control on VCS URLs passed to pip are advised to upgrade. (`12119 <https://github.com/pypa/pip/issues/12119>`_) Vendored Libraries ------------------ - Upgrade certifi to 2023.5.7 - Upgrade platformdirs to 3.8.1 - Upgrade pygments to 2.15.1 - Upgrade pyparsing to 3.1.0 - Upgrade Requests to 2.31.0 - Upgrade rich to 13.4.2 - Upgrade setuptools to 68.0.0 - Updated typing_extensions to 4.6.0 - Upgrade typing_extensions to 4.7.1 - Upgrade urllib3 to 1.26.16 ``` ### 23.1.2 ``` =================== Vendored Libraries ------------------ - Upgrade setuptools to 67.7.2 ``` ### 23.1.1 ``` =================== Bug Fixes --------- - Revert `11487 <https://github.com/pypa/pip/pull/11487>`_, as it causes issues with virtualenvs created by the Windows Store distribution of Python. (`#11987 <https://github.com/pypa/pip/issues/11987>`_) Vendored Libraries ------------------ - Revert pkg_resources (via setuptools) back to 65.6.3 Improved Documentation ---------------------- - Update documentation to reflect the new behavior of using the cache of locally built wheels in hash-checking mode. (`11967 <https://github.com/pypa/pip/issues/11967>`_) ``` ### 23.1 ``` ================= Deprecations and Removals ------------------------- - Remove support for the deprecated ``--install-options``. (`11358 <https://github.com/pypa/pip/issues/11358>`_) - ``--no-binary`` does not imply ``setup.py install`` anymore. Instead a wheel will be built locally and installed. (`11451 <https://github.com/pypa/pip/issues/11451>`_) - ``--no-binary`` does not disable the cache of locally built wheels anymore. It only means "don't download wheels". (`11453 <https://github.com/pypa/pip/issues/11453>`_) - Deprecate ``--build-option`` and ``--global-option``. Users are invited to switch to ``--config-settings``. (`11859 <https://github.com/pypa/pip/issues/11859>`_) - Using ``--config-settings`` with projects that don't have a ``pyproject.toml`` now prints a deprecation warning. In the future the presence of config settings will automatically enable the default build backend for legacy projects and pass the settings to it. (`11915 <https://github.com/pypa/pip/issues/11915>`_) - Remove ``setup.py install`` fallback when building a wheel failed for projects without ``pyproject.toml``. (`8368 <https://github.com/pypa/pip/issues/8368>`_) - When the ``wheel`` package is not installed, pip now uses the default build backend instead of ``setup.py install`` and ``setup.py develop`` for project without ``pyproject.toml``. (`8559 <https://github.com/pypa/pip/issues/8559>`_) Features -------- - Specify egg-link location in assertion message when it does not match installed location to provide better error message for debugging. (`10476 <https://github.com/pypa/pip/issues/10476>`_) - Present conflict information during installation after each choice that is rejected (pass ``-vv`` to ``pip install`` to show it) (`10937 <https://github.com/pypa/pip/issues/10937>`_) - Display dependency chain on each Collecting/Processing log line. (`11169 <https://github.com/pypa/pip/issues/11169>`_) - Support a per-requirement ``--config-settings`` option in requirements files. (`11325 <https://github.com/pypa/pip/issues/11325>`_) - The ``--config-settings``/``-C`` option now supports using the same key multiple times. When the same key is specified multiple times, all values are passed to the build backend as a list, as opposed to the previous behavior, where pip would only pass the last value if the same key was used multiple times. (`11681 <https://github.com/pypa/pip/issues/11681>`_) - Add ``-C`` as a short version of the ``--config-settings`` option. (`11786 <https://github.com/pypa/pip/issues/11786>`_) - Reduce the number of resolver rounds, since backjumping makes the resolver more efficient in finding solutions. This also makes pathological cases fail quicker. (`11908 <https://github.com/pypa/pip/issues/11908>`_) - Warn if ``--hash`` is used on a line without requirement in a requirements file. (`11935 <https://github.com/pypa/pip/issues/11935>`_) - Stop propagating CLI ``--config-settings`` to the build dependencies. They already did not propagate to requirements provided in requirement files. To pass the same config settings to several requirements, users should provide the requirements as CLI arguments. (`11941 <https://github.com/pypa/pip/issues/11941>`_) - Support wheel cache when using ``--require-hashes``. (`5037 <https://github.com/pypa/pip/issues/5037>`_) - Add ``--keyring-provider`` flag. See the Authentication page in the documentation for more info. (`8719 <https://github.com/pypa/pip/issues/8719>`_) - In the case of virtual environments, configuration files are now also included from the base installation. (`9752 <https://github.com/pypa/pip/issues/9752>`_) Bug Fixes --------- - Fix grammar by changing "A new release of pip available:" to "A new release of pip is available:" in the notice used for indicating that. (`11529 <https://github.com/pypa/pip/issues/11529>`_) - Normalize paths before checking if installed scripts are on PATH. (`11719 <https://github.com/pypa/pip/issues/11719>`_) - Correct the way to decide if keyring is available. (`11774 <https://github.com/pypa/pip/issues/11774>`_) - More consistent resolution backtracking by removing legacy hack related to setuptools resolution (`11837 <https://github.com/pypa/pip/issues/11837>`_) - Include ``AUTHORS.txt`` in pip's wheels. (`11882 <https://github.com/pypa/pip/issues/11882>`_) - The ``uninstall`` and ``install --force-reinstall`` commands no longer call ``normalize_path()`` repeatedly on the same paths. Instead, these results are cached for the duration of an uninstall operation, resulting in improved performance, particularly on Windows. (`11889 <https://github.com/pypa/pip/issues/11889>`_) - Fix and improve the parsing of hashes embedded in URL fragments. (`11936 <https://github.com/pypa/pip/issues/11936>`_) - When package A depends on package B provided as a direct URL dependency including a hash embedded in the link, the ``--require-hashes`` option did not warn when user supplied hashes were missing for package B. (`11938 <https://github.com/pypa/pip/issues/11938>`_) - Correctly report ``requested_extras`` in the installation report when extras are specified for a local directory installation. (`11946 <https://github.com/pypa/pip/issues/11946>`_) - When installing an archive from a direct URL or local file, populate ``download_info.info.hashes`` in the installation report, in addition to the legacy ``download_info.info.hash`` key. (`11948 <https://github.com/pypa/pip/issues/11948>`_) Vendored Libraries ------------------ - Upgrade msgpack to 1.0.5 - Patch pkg_resources to remove dependency on ``jaraco.text``. - Upgrade platformdirs to 3.2.0 - Upgrade pygments to 2.14.0 - Upgrade resolvelib to 1.0.1 - Upgrade rich to 13.3.3 - Upgrade setuptools to 67.6.1 - Upgrade tenacity to 8.2.2 - Upgrade typing_extensions to 4.5.0 - Upgrade urllib3 to 1.26.15 Improved Documentation ---------------------- - Cross-reference the ``--python`` flag from the ``--prefix`` flag, and mention limitations of ``--prefix`` regarding script installation. (`11775 <https://github.com/pypa/pip/issues/11775>`_) - Add SECURITY.md to make the policy offical. (`11809 <https://github.com/pypa/pip/issues/11809>`_) - Add username to Git over SSH example. (`11838 <https://github.com/pypa/pip/issues/11838>`_) - Quote extras in the pip install docs to guard shells with default glob qualifiers, like zsh. (`11842 <https://github.com/pypa/pip/issues/11842>`_) - Make it clear that requirements/constraints file can be a URL (`11954 <https://github.com/pypa/pip/issues/11954>`_) ``` ### 23.0.1 ``` =================== Features -------- - Ignore PIP_REQUIRE_VIRTUALENV for ``pip index`` (`11671 <https://github.com/pypa/pip/issues/11671>`_) - Implement ``--break-system-packages`` to permit installing packages into ``EXTERNALLY-MANAGED`` Python installations. (`11780 <https://github.com/pypa/pip/issues/11780>`_) Bug Fixes --------- - Improve handling of isolated build environments on platforms that customize the Python's installation schemes, such as Debian and Homebrew. (`11740 <https://github.com/pypa/pip/issues/11740>`_) - Do not crash in presence of misformatted hash field in ``direct_url.json``. (`11773 <https://github.com/pypa/pip/issues/11773>`_) ``` ### 23.0 ``` ================= Features -------- - Change the hashes in the installation report to be a mapping. Emit the ``archive_info.hashes`` dictionary in ``direct_url.json``. (`11312 <https://github.com/pypa/pip/issues/11312>`_) - Implement logic to read the ``EXTERNALLY-MANAGED`` file as specified in :pep:`668`. This allows a downstream Python distributor to prevent users from using pip to modify the externally managed environment. (`11381 <https://github.com/pypa/pip/issues/11381>`_) - Enable the use of ``keyring`` found on ``PATH``. This allows ``keyring`` installed using ``pipx`` to be used by ``pip``. (`11589 <https://github.com/pypa/pip/issues/11589>`_) - The inspect and installation report formats are now declared stable, and their version has been bumped from ``0`` to ``1``. (`11757 <https://github.com/pypa/pip/issues/11757>`_) Bug Fixes --------- - Wheel cache behavior is restored to match previous versions, allowing the cache to find existing entries. (`11527 <https://github.com/pypa/pip/issues/11527>`_) - Use the "venv" scheme if available to obtain prefixed lib paths. (`11598 <https://github.com/pypa/pip/issues/11598>`_) - Deprecated a historical ambiguity in how ``egg`` fragments in URL-style requirements are formatted and handled. ``egg`` fragments that do not look like :pep:`508` names now produce a deprecation warning. (`11617 <https://github.com/pypa/pip/issues/11617>`_) - Fix scripts path in isolated build environment on Debian. (`11623 <https://github.com/pypa/pip/issues/11623>`_) - Make ``pip show`` show the editable location if package is editable (`11638 <https://github.com/pypa/pip/issues/11638>`_) - Stop checking that ``wheel`` is present when ``build-system.requires`` is provided without ``build-system.build-backend`` as ``setuptools`` (which we still check for) will inject it anyway. (`11673 <https://github.com/pypa/pip/issues/11673>`_) - Fix an issue when an already existing in-memory distribution would cause exceptions in ``pip install`` (`11704 <https://github.com/pypa/pip/issues/11704>`_) Vendored Libraries ------------------ - Upgrade certifi to 2022.12.7 - Upgrade chardet to 5.1.0 - Upgrade colorama to 0.4.6 - Upgrade distro to 1.8.0 - Remove pep517 from vendored packages - Upgrade platformdirs to 2.6.2 - Add pyproject-hooks 1.0.0 - Upgrade requests to 2.28.2 - Upgrade rich to 12.6.0 - Upgrade urllib3 to 1.26.14 Improved Documentation ---------------------- - Fixed the description of the option "--install-options" in the documentation (`10265 <https://github.com/pypa/pip/issues/10265>`_) - Remove mention that editable installs are necessary for pip freeze to report the VCS URL. (`11675 <https://github.com/pypa/pip/issues/11675>`_) - Clarify that the egg URL fragment is only necessary for editable VCS installs, and otherwise not necessary anymore. (`11676 <https://github.com/pypa/pip/issues/11676>`_) ``` ### 22.3.1 ``` =================== Bug Fixes --------- - Fix entry point generation of ``pip.X``, ``pipX.Y``, and ``easy_install-X.Y`` to correctly account for multi-digit Python version segments (e.g. the "11" part of 3.11). (`11547 <https://github.com/pypa/pip/issues/11547>`_) ``` ### 22.3 ``` ================= Deprecations and Removals ------------------------- - Deprecate ``--install-options`` which forces pip to use the deprecated ``install`` command of ``setuptools``. (`11358 <https://github.com/pypa/pip/issues/11358>`_) - Deprecate installation with 'setup.py install' when no-binary is enabled for source distributions without 'pyproject.toml'. (`11452 <https://github.com/pypa/pip/issues/11452>`_) - Deprecate --no-binary`` disabling the wheel cache. (`11454 <https://github.com/pypa/pip/issues/11454>`_) - Remove ``--use-feature=2020-resolver`` opt-in flag. This was supposed to be removed in 21.0, but missed during that release cycle. (`11493 <https://github.com/pypa/pip/issues/11493>`_) - Deprecate installation with 'setup.py install' when the 'wheel' package is absent for source distributions without 'pyproject.toml'. (`8559 <https://github.com/pypa/pip/issues/8559>`_) - Remove the ability to use ``pip list --outdated`` in combination with ``--format=freeze``. (`9789 <https://github.com/pypa/pip/issues/9789>`_) Features -------- - Use ``shell=True`` for opening the editor with ``pip config edit``. (`10716 <https://github.com/pypa/pip/issues/10716>`_) - Use the ``data-dist-info-metadata`` attribute from :pep:`658` to resolve distribution metadata without downloading the dist yet. (`11111 <https://github.com/pypa/pip/issues/11111>`_) - Add an option to run the test suite with pip built as a zipapp. (`11250 <https://github.com/pypa/pip/issues/11250>`_) - Add a ``--python`` option to allow pip to manage Python environments other than the one pip is installed in. (`11320 <https://github.com/pypa/pip/issues/11320>`_) - Document the new (experimental) zipapp distribution of pip. (`11459 <https://github.com/pypa/pip/issues/11459>`_) - Use the much faster 'bzr co --lightweight' to obtain a copy of a Bazaar tree. (`5444 <https://github.com/pypa/pip/issues/5444>`_) Bug Fixes --------- - Fix ``--no-index`` when ``--index-url`` or ``--extra-index-url`` is specified inside a requirements file. (`11276 <https://github.com/pypa/pip/issues/11276>`_) - Ensure that the candidate ``pip`` executable exists, when checking for a new version of pip. (`11309 <https://github.com/pypa/pip/issues/11309>`_) - Ignore distributions with invalid ``Name`` in metadata instead of crashing, when using the ``importlib.metadata`` backend. (`11352 <https://github.com/pypa/pip/issues/11352>`_) - Raise RequirementsFileParseError when parsing malformed requirements options that can't be successfully parsed by shlex. (`11491 <https://github.com/pypa/pip/issues/11491>`_) - Fix build environment isolation on some system Pythons. (`6264 <https://github.com/pypa/pip/issues/6264>`_) Vendored Libraries ------------------ - Upgrade certifi to 2022.9.24 - Upgrade distlib to 0.3.6 - Upgrade idna to 3.4 - Upgrade pep517 to 0.13.0 - Upgrade pygments to 2.13.0 - Upgrade tenacity to 8.1.0 - Upgrade typing_extensions to 4.4.0 - Upgrade urllib3 to 1.26.12 Improved Documentation ---------------------- - Mention that --quiet must be used when writing the installation report to stdout. (`11357 <https://github.com/pypa/pip/issues/11357>`_) ``` ### 22.2.2 ``` =================== Bug Fixes --------- - Avoid ``AttributeError`` when removing the setuptools-provided ``_distutils_hack`` and it is missing its implementation. (`11314 <https://github.com/pypa/pip/issues/11314>`_) - Fix import error when reinstalling pip in user site. (`11319 <https://github.com/pypa/pip/issues/11319>`_) - Show pip deprecation warnings by default. (`11330 <https://github.com/pypa/pip/issues/11330>`_) ``` ### 22.2.1 ``` =================== Bug Fixes --------- - Send the pip upgrade prompt to stderr. (`11282 <https://github.com/pypa/pip/issues/11282>`_) - Ensure that things work correctly in environments where setuptools-injected ``distutils`` is available by default. This is done by cooperating with setuptools' injection logic to ensure that pip uses the ``distutils`` from the Python standard library instead. (`11298 <https://github.com/pypa/pip/issues/11298>`_) - Clarify that ``pip cache``'s wheels-related output is about locally built wheels only. (`11300 <https://github.com/pypa/pip/issues/11300>`_) ``` ### 22.2 ``` ================= Deprecations and Removals ------------------------- - Remove the ``html5lib`` deprecated feature flag. (`10825 <https://github.com/pypa/pip/issues/10825>`_) - Remove ``--use-deprecated=backtrack-on-build-failures``. (`11241 <https://github.com/pypa/pip/issues/11241>`_) Features -------- - Add support to use `truststore <https://pypi.org/project/truststore/>`_ as an alternative SSL certificate verification backend. The backend can be enabled on Python 3.10 and later by installing ``truststore`` into the environment, and adding the ``--use-feature=truststore`` flag to various pip commands. ``truststore`` differs from the current default verification backend (provided by ``certifi``) in it uses the operating system’s trust store, which can be better controlled and augmented to better support non-standard certificates. Depending on feedback, pip may switch to this as the default certificate verification backend in the future. (`11082 <https://github.com/pypa/pip/issues/11082>`_) - Add ``--dry-run`` option to ``pip install``, to let it print what it would install but not actually change anything in the target environment. (`11096 <https://github.com/pypa/pip/issues/11096>`_) - Record in wheel cache entries the URL of the original artifact that was downloaded to build the cached wheels. The record is named ``origin.json`` and uses the PEP 610 Direct URL format. (`11137 <https://github.com/pypa/pip/issues/11137>`_) - Support `PEP 691 <https://peps.python.org/pep-0691/>`_. (`#11158 <https://github.com/pypa/pip/issues/11158>`_) - pip's deprecation warnings now subclass the built-in ``DeprecationWarning``, and can be suppressed by running the Python interpreter with ``-W ignore::DeprecationWarning``. (`11225 <https://github.com/pypa/pip/issues/11225>`_) - Add ``pip inspect`` command to obtain the list of installed distributions and other information about the Python environment, in JSON format. (`11245 <https://github.com/pypa/pip/issues/11245>`_) - Significantly speed up isolated environment creation, by using the same sources for pip instead of creating a standalone installation for each environment. (`11257 <https://github.com/pypa/pip/issues/11257>`_) - Add an experimental ``--report`` option to the install command to generate a JSON report of what was installed. In combination with ``--dry-run`` and ``--ignore-installed`` it can be used to resolve the requirements. (`53 <https://github.com/pypa/pip/issues/53>`_) Bug Fixes --------- - Fix ``pip install --pre`` for packages with pre-release build dependencies defined both in ``pyproject.toml``'s ``build-system.requires`` and ``setup.py``'s ``setup_requires``. (`10222 <https://github.com/pypa/pip/issues/10222>`_) - When pip rewrites the shebang line in a script during wheel installation, update the hash and size in the corresponding ``RECORD`` file entry. (`10744 <https://github.com/pypa/pip/issues/10744>`_) - Do not consider a ``.dist-info`` directory found inside a wheel-like zip file as metadata for an installed distribution. A package in a wheel is (by definition) not installed, and is not guaranteed to work due to how a wheel is structured. (`11217 <https://github.com/pypa/pip/issues/11217>`_) - Use ``importlib.resources`` to read the ``vendor.txt`` file in ``pip debug``. This makes the command safe for use from a zipapp. (`11248 <https://github.com/pypa/pip/issues/11248>`_) - Make the ``--use-pep517`` option of the ``download`` command apply not just to the requirements specified on the command line, but to their dependencies, as well. (`9523 <https://github.com/pypa/pip/issues/9523>`_) Process ------- - Remove reliance on the stdlib cgi module, which is deprecated in Python 3.11. Vendored Libraries ------------------ - Remove html5lib. - Upgrade certifi to 2022.6.15 - Upgrade chardet to 5.0.0 - Upgrade colorama to 0.4.5 - Upgrade distlib to 0.3.5 - Upgrade msgpack to 1.0.4 - Upgrade pygments to 2.12.0 - Upgrade pyparsing to 3.0.9 - Upgrade requests to 2.28.1 - Upgrade rich to 12.5.1 - Upgrade typing_extensions to 4.3.0 - Upgrade urllib3 to 1.26.10 ```Links
