Subject: [pypi-announce] upgrade to pip 20.2 -- plus changes coming in 20.3

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
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
The full changelog is at <https://pip.pypa.io/en/stable/news/>.
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.
