Changelog

Sourced from pip's changelog.

20.2.2 (2020-08-11)

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) <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) <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) <https://github.com/pypa/pip/issues/8701>, [#8716](https://github.com/pypa/pip/issues/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) <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) <https://github.com/pypa/pip/issues/8724>_)

20.2.1 (2020-08-04)

Features

• Ignore require-virtualenv in pip list ([#8603](https://github.com/pypa/pip/issues/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) <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) <https://github.com/pypa/pip/issues/8654>_)
• Fix SVN version detection for alternative SVN distributions. ([#8665](https://github.com/pypa/pip/issues/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) <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) <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) <https://github.com/pypa/pip/issues/8371>_)
• Fix feature flag name in docs. ([#8660](https://github.com/pypa/pip/issues/8660) <https://github.com/pypa/pip/issues/8660>_)
