A new release of pip is out. Please see below, upgrade, and let us know if you start to have trouble (for instance, with Carpentries lessons in Python). 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 . We do want to hear about it if your installations of packages break, even if those upstreams ought to fix their requirements. 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*. -- Sumana Harihareswara project manager for pip, on contract with Python Software Foundation Changeset Consulting, https://changeset.nyc ------------------------------------------ The Carpentries: discuss Permalink: https://carpentries.topicbox.com/groups/discuss/T39f95d9566819b09-Ma80a84746de8901b7b8122b4 Delivery options: https://carpentries.topicbox.com/groups/discuss/subscription
