[PSF-Community] Fwd: [pypi-announce] upgrade to pip 20.2 -- plus changes coming in 20.3

[Sumana Harihareswara]

A new release of pip is out. Please see below, upgrade, and let us know 
if you or your users start to have trouble. In particular, we need your 
feedback on the beta of the new dependency resolver, because we want to 
make it the default in the October release.

Please report bugs using this survey: 
https://tools.simplysecure.org/survey/index.php?r=survey/index&sid=989272&lang=en 
.

And please **spread the word** by pointing to this blog post: 
https://blog.python.org/2020/07/upgrade-pip-20-2-changes-20-3.html -- 
spread the word on Hacker News, Reddit, Twitter, Facebook, Dev.to, 
Telegram, relevant Stack Overflow answers, your favorite Slacks and 
Discords, etc. Most of the people this will affect do not keep up with 
Python-specific developer news. Help them get the heads-up before 
October, and help us get their bug reports.

best,
Sumana Harihareswara, pip project manager

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.
