On behalf of the Python Packaging Authority, I am pleased to announce the release of pip 20.2. Please upgrade for speed improvements, bug fixes, and better logging. You can install it by running python -m pip install --upgrade pip.

We make major releases each quarter, so this is the first new release since 20.1 in April.

NOTICE: This release includes the beta of the next-generation dependency resolver. It is significantly stricter and more consistent when it receives incompatible instructions, and reduces support for certain kinds of constraints files, so some workarounds and workflows may break. Please test it with the `--use-feature=2020-resolver` flag. Please see our guide on how to test and migrate, and how to report issues https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-resolver-in-20-2-2020.

The new dependency resolver is *off by default* because it is *not yet ready for everyday use*.

For release highlights and thank-yous, please see https://blog.python.org/2020/07/upgrade-pip-20-2-changes-20-3.html . The full changelog is at https://pip.pypa.io/en/stable/news/.

Future:

We plan to make pip's next quarterly release, 20.3, in October 2020. We are preparing to change the default dependency resolution behavior and make the new resolver the default in pip 20.3.
