[dependabot-preview]

Bumps pip from 20.0.2 to 20.1.

Changelog

Sourced from pip's changelog.

20.1 (2020-04-28)

Process

• Document that pip 21.0 will drop support for Python 2.7.

Features

• Add pip cache dir to show the cache directory. (#7350)

Bug Fixes

• Abort pip cache commands early when cache is disabled. (#8124)
• Correctly set permissions on metadata files during wheel installation, to permit non-privileged users to read from system site-packages. (#8139)

20.1b1 (2020-04-21)

Deprecations and Removals

• Remove emails from AUTHORS.txt to prevent usage for spamming, and only populate names in AUTHORS.txt at time of release (#5979)
• Remove deprecated --skip-requirements-regex option. (#7297)
• Building of local directories is now done in place, instead of a temporary location containing a copy of the directory tree. (#7555)
• Remove unused tests/scripts/test_all_pip.py test script and the tests/scripts folder. (#7680)

Features

• pip now implements PEP 610, so pip freeze has better fidelity in presence of distributions installed from Direct URL requirements. (#609)
• Add pip cache command for inspecting/managing pip's wheel cache. (#6391)
• Raise error if --user and --target are used together in pip install (#7249)
• Significantly improve performance when --find-links points to a very large HTML page. (#7729)
• Indicate when wheel building is skipped, due to lack of the wheel package. (#7768)
• Change default behaviour to always cache responses from trusted-host source. (#7847)
• An alpha version of a new resolver is available via --unstable-feature=resolver. (#988)

Bug Fixes

• Correctly freeze a VCS editable package when it is nested inside another VCS repository. (#3988)
• Correctly handle %2F in URL parameters to avoid accidentally unescape them into /. (#6446)
• Reject VCS URLs with an empty revision. (#7402)
• Warn when an invalid URL is passed with --index-url (#7430)
• Use better mechanism for handling temporary files, when recording metadata about installed files (RECORD) and the installer (INSTALLER). (#7699)
• Correctly detect global site-packages availability of virtual environments created by PyPA’s virtualenv>=20.0. (#7718)
