(`#4256 <https://github.com/pypa/pip/issues/4256>`_) +- Deprecate support for Python 3.5 (`#8181 <https://github.com/pypa/pip/issues/8181>`_) +- 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>`_) +- Deprecate ``--find-links`` option in ``pip freeze`` (`#9069 <https://github.com/pypa/pip/issues/9069>`_) + +Features +-------- + +- Add ``--exclude`` option to ``pip freeze`` and ``pip list`` commands to explicitly exclude packages from the output. (`#4256 <https://github.com/pypa/pip/issues/4256>`_) +- Allow multiple values for --abi and --platform. (`#6121 <https://github.com/pypa/pip/issues/6121>`_) +- Add option ``--format`` to subcommand ``list`` of ``pip cache``, with ``abspath`` choice to output the full path of a wheel file. (`#8355 <https://github.com/pypa/pip/issues/8355>`_) +- Improve error message friendliness when an environment has packages with + corrupted metadata. (`#8676 <https://github.com/pypa/pip/issues/8676>`_) +- 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>`_) +- Check the download directory for existing wheels to possibly avoid + fetching metadata when the ``fast-deps`` feature is used with + ``pip wheel`` and ``pip download``. (`#8804 <https://github.com/pypa/pip/issues/8804>`_) +- When installing a git URL that refers to a commit that is not available locally + after git clone, attempt to fetch it from the remote. (`#8815 <https://github.com/pypa/pip/issues/8815>`_) +- Include http subdirectory in ``pip cache info`` and ``pip cache purge`` commands. (`#8892 <https://github.com/pypa/pip/issues/8892>`_) +- 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>`_) +- Support Python 3.9. (`#8971 <https://github.com/pypa/pip/issues/8971>`_) +- Log an informational message when backtracking takes multiple rounds on a specific package. (`#8975 <https://github.com/pypa/pip/issues/8975>`_) +- Switch to the new dependency resolver by default. (`#9019 <https://github.com/pypa/pip/issues/9019>`_) +- Remove the ``--build-dir`` option, as per the deprecation. (`#9049 <https://github.com/pypa/pip/issues/9049>`_) + +Bug Fixes +--------- + +- Propagate ``--extra-index-url`` from requirements file properly to session auth, + so that keyring auth will work as expected. (`#8103 <https://github.com/pypa/pip/issues/8103>`_) +- Allow specifying verbosity and quiet level via configuration files + and environment variables. Previously these options were treated as + boolean values when read from there while through CLI the level can be + specified. (`#8578 <https://github.com/pypa/pip/issues/8578>`_) +- Only converts Windows path to unicode on Python 2 to avoid regressions when a + POSIX environment does not configure the file system encoding correctly. (`#8658 <https://github.com/pypa/pip/issues/8658>`_) +- List downloaded distributions before exiting ``pip download`` + when using the new resolver to make the behavior the same as + that on the legacy resolver. (`#8696 <https://github.com/pypa/pip/issues/8696>`_) +- New resolver: Pick up hash declarations in constraints files and use them to + filter available distributions. (`#8792 <https://github.com/pypa/pip/issues/8792>`_) +- Avoid polluting the destination directory by resolution artifacts + when the new resolver is used for ``pip download`` or ``pip wheel``. (`#8827 <https://github.com/pypa/pip/issues/8827>`_) +- 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>`_) +- Tweak the output during dependency resolution in the new resolver. (`#8861 <https://github.com/pypa/pip/issues/8861>`_) +- Correctly search for installed distributions in new resolver logic in order + to not miss packages (virtualenv packages from system-wide-packages for example) (`#8963 <https://github.com/pypa/pip/issues/8963>`_) +- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file + with editable=True. Render it as a non-editable ``file://`` URL until modern + editable installs are standardized and supported. (`#8996 <https://github.com/pypa/pip/issues/8996>`_) + +Vendored Libraries +------------------ + +- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed. + It is mandatory for ``pip debug`` command. + +Improved Documentation +---------------------- + +- Add documentation for '.netrc' support. (`#7231 <https://github.com/pypa/pip/issues/7231>`_) +- Add OS tabs for OS-specific commands. (`#7311 <https://github.com/pypa/pip/issues/7311>`_) +- Add note and example on keyring support for index basic-auth (`#8636 <https://github.com/pypa/pip/issues/8636>`_) +- Added initial UX feedback widgets to docs. (`#8783 <https://github.com/pypa/pip/issues/8783>`_, `#8848 <https://github.com/pypa/pip/issues/8848>`_) +- Add ux documentation (`#8807 <https://github.com/pypa/pip/issues/8807>`_) +- Update user docs to reflect new resolver as default in 20.3. (`#9044 <https://github.com/pypa/pip/issues/9044>`_) +- Improve migration guide to reflect changes in new resolver behavior. (`#9056 <https://github.com/pypa/pip/issues/9056>`_) + + 20.2.4 (2020-10-16) =================== |
