| 13 | +================= |
| 14 | + |
| 15 | +Deprecations and Removals |
| 16 | +------------------------- |
| 17 | + |
| 18 | +- Remove the ``html5lib`` deprecated feature flag. (`#10825 <https://github.com/pypa/pip/issues/10825>`_) |
| 19 | +- Remove ``--use-deprecated=backtrack-on-build-failures``. (`#11241 <https://github.com/pypa/pip/issues/11241>`_) |
| 20 | + |
| 21 | +Features |
| 22 | +-------- |
| 23 | + |
| 24 | +- Add support to use `truststore <https://pypi.org/project/truststore/>`_ as an |
| 25 | + alternative SSL certificate verification backend. The backend can be enabled on Python |
| 26 | + 3.10 and later by installing ``truststore`` into the environment, and adding the |
| 27 | + ``--use-feature=truststore`` flag to various pip commands. |
| 28 | + |
| 29 | + ``truststore`` differs from the current default verification backend (provided by |
| 30 | + ``certifi``) in it uses the operating system’s trust store, which can be better |
| 31 | + controlled and augmented to better support non-standard certificates. Depending on |
| 32 | + feedback, pip may switch to this as the default certificate verification backend in |
| 33 | + the future. (`#11082 <https://github.com/pypa/pip/issues/11082>`_) |
| 34 | +- Add ``--dry-run`` option to ``pip install``, to let it print what it would install but |
| 35 | + not actually change anything in the target environment. (`#11096 <https://github.com/pypa/pip/issues/11096>`_) |
| 36 | +- Record in wheel cache entries the URL of the original artifact that was downloaded |
| 37 | + to build the cached wheels. The record is named ``origin.json`` and uses the PEP 610 |
| 38 | + Direct URL format. (`#11137 <https://github.com/pypa/pip/issues/11137>`_) |
| 39 | +- Support `PEP 691 <https://peps.python.org/pep-0691/>`_. (`#11158 <https://github.com/pypa/pip/issues/11158>`_) |
| 40 | +- pip's deprecation warnings now subclass the built-in ``DeprecationWarning``, and |
| 41 | + can be suppressed by running the Python interpreter with |
| 42 | + ``-W ignore::DeprecationWarning``. (`#11225 <https://github.com/pypa/pip/issues/11225>`_) |
| 43 | +- Add ``pip inspect`` command to obtain the list of installed distributions and other |
| 44 | + information about the Python environment, in JSON format. (`#11245 <https://github.com/pypa/pip/issues/11245>`_) |
| 45 | +- Significantly speed up isolated environment creation, by using the same |
| 46 | + sources for pip instead of creating a standalone installation for each |
| 47 | + environment. (`#11257 <https://github.com/pypa/pip/issues/11257>`_) |
| 48 | +- Add an experimental ``--report`` option to the install command to generate a JSON report |
| 49 | + of what was installed. In combination with ``--dry-run`` and ``--ignore-installed`` it |
| 50 | + can be used to resolve the requirements. (`#53 <https://github.com/pypa/pip/issues/53>`_) |
| 51 | + |
| 52 | +Bug Fixes |
| 53 | +--------- |
| 54 | + |
| 55 | +- Fix ``pip install --pre`` for packages with pre-release build dependencies defined |
| 56 | + both in ``pyproject.toml``'s ``build-system.requires`` and ``setup.py``'s |
| 57 | + ``setup_requires``. (`#10222 <https://github.com/pypa/pip/issues/10222>`_) |
| 58 | +- When pip rewrites the shebang line in a script during wheel installation, |
| 59 | + update the hash and size in the corresponding ``RECORD`` file entry. (`#10744 <https://github.com/pypa/pip/issues/10744>`_) |
| 60 | +- Do not consider a ``.dist-info`` directory found inside a wheel-like zip file |
| 61 | + as metadata for an installed distribution. A package in a wheel is (by |
| 62 | + definition) not installed, and is not guaranteed to work due to how a wheel is |
| 63 | + structured. (`#11217 <https://github.com/pypa/pip/issues/11217>`_) |
| 64 | +- Use ``importlib.resources`` to read the ``vendor.txt`` file in ``pip debug``. |
| 65 | + This makes the command safe for use from a zipapp. (`#11248 <https://github.com/pypa/pip/issues/11248>`_) |
| 66 | +- Make the ``--use-pep517`` option of the ``download`` command apply not just |
| 67 | + to the requirements specified on the command line, but to their dependencies, |
| 68 | + as well. (`#9523 <https://github.com/pypa/pip/issues/9523>`_) |
| 69 | + |
| 70 | +Process |
| 71 | +------- |
| 72 | + |
| 73 | +- Remove reliance on the stdlib cgi module, which is deprecated in Python 3.11. |
