pip 20.3 release (heads-up for potential disruption)
On behalf of the Python Packaging Authority, I am pleased to announce that we have just released pip 20.3, a new version of pip. You can install it by running `python -m pip install --upgrade pip`. This is an important and disruptive release -- we explained why in a blog post last year https://pyfound.blogspot.com/2019/12/moss-czi-support-pip.html . We even made a video about it: https://www.youtube.com/watch?v=B4GQCBBsuNU . Blog post with details: https://pyfound.blogspot.com/2020/11/pip-20-3-new-resolver.html Highlights include: * **DISRUPTION**: Switch to the new dependency resolver by default. Watch out for changes in handling editable installs, constraints files, and more: https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-resolver-in-20-3-2020 * **DEPRECATION**: Deprecate support for Python 3.5 (to be removed in pip 21.0) * **DEPRECATION**: pip freeze will stop filtering the pip, setuptools, distribute and wheel packages from pip freeze output in a future version. To keep the previous behavior, users should use the new `--exclude` option. * Support for PEP 600: Future ‘manylinux’ Platform Tags for Portable Linux Built Distributions. * Add support for MacOS Big Sur compatibility tags. The new resolver is now *on by default*. 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 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-20-3-2020 . You can use the deprecated (old) resolver, using the flag `--use-deprecated=legacy-resolver`, until we remove it in the pip 21.0 release in January 2021. In pip 21.0 we will also remove support for Python 2.7. You can find more details (including deprecations and removals) [in the changelog](https://pip.pypa.io/en/stable/news/), and you can find thank-yous and instructions on reporting issues at https://pyfound.blogspot.com/2020/11/pip-20-3-new-resolver.html .

Pip users: big change coming this month
Changes are coming to pip, Python's package installation tool, in October 2020. Please read and share this migration guide: https://pip.pypa.io/en/latest/user_guide/#changes-to-the-pip-dependency-resolver-in-20-2-2020 . We're working on improving the Python packaging toolchain, foundational work that will (in the long run) make the whole Python package installation experience way less confusing. The pip team made a 2-minute video to explain what's up: https://youtu.be/B4GQCBBsuNU We are also doing user experience studies, and want you to sign up if you ever do anything with Python (whatever your level of skill/experience): http://www.ei8fdb.org/thoughts/2020/03/pip-ux-study-recruitment/ https://mastodon.social/@brainwane/104950044427849411 is a good toot to boost, and https://twitter.com/ThePSF/status/1311038036013199363 is a good tweet to retweet, if you want to help us get the word out.

pip 20.2 release, plus changes coming in 20.3
On behalf of the Python Packaging Authority, I am pleased to announce that we have just released pip 20.2, a new version of pip. You can install it by running python -m pip install --upgrade pip. The highlights for this release are: - The beta of the next-generation dependency resolver is available - Faster installations from wheel files - Improved handling of wheels containing non-ASCII file contents - Faster `pip list` using parallelized network operations - Installed packages now contain metadata about whether they were directly requested by the user (PEP 376’s REQUESTED file) The new dependency resolver is *off by default* because it is *not yet ready for everyday use*. The new dependency resolver 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>. We are preparing to change the default dependency resolution behavior and make the new resolver the default in pip 20.3 (in October 2020). This release also partially optimizes pip’s network usage during installation (as part of a Google Summer of Code project by McSinyx <https://summerofcode.withgoogle.com/projects/#5428041779511296>). Please test it with `pip install --use-feature=2020-resolver --use-feature=fast-deps` and report bugs to the issue tracker <https://github.com/pypa/pip/issues/new?template=bug-report.md>. This functionality is *still experimental* and *not ready for everyday use*. You can find more details (including deprecations and removals) in the changelog <https://pip.pypa.io/en/stable/news/>. As with all pip releases, a significant amount of the work was contributed by pip’s user community. Huge thanks to all who have contributed, whether through code, documentation, issue reports and/or discussion. Your help keeps pip improving, and is hugely appreciated. Specific thanks go to Mozilla (through its Mozilla Open Source Support <https://www.mozilla.org/en-US/moss/> Awards) and to the Chan Zuckerberg Initiative <https://chanzuckerberg.com/eoss/> DAF, an advised fund of Silicon Valley Community Foundation, for their funding that enabled substantial work on the new resolver. -- Sumana Harihareswara pip project manager via contract with PSF Changeset Consulting https://changeset.nyc ___ Python-announce-list mailing list -- python-announce-list@python.org To unsubscribe send an email to python-announce-list-le...@python.org https://mail.python.org/mailman3/lists/python-announce-list.python.org/ Member address: arch...@mail-archive.com
Upgrade to pip 20.1
On behalf of the Python Packaging Authority, I am pleased to announce that a new version of pip, pip 20.1, has been released. We make major releases each quarter, and so this is the first new release since 20.0.2 in January. Please upgrade. To install pip 20.1, you can run: python -m pip install --upgrade pip What's new: The highlights for this release are: * Significant speedups when building local directories, by changing behavior to perform in-place builds, instead of copying to temporary directories. * Significant speedups in `pip list --outdated`, by parallelizing network access. This is the first instance of parallel code within pip's codebase. * A new `pip cache` command, which makes it possible to introspect and manage pip's cache directory. * Better `pip freeze` for packages installed from direct URLs, enabled by the implementation of PEP 610. The full changelog: https://pip.pypa.io/en/latest/news/ . This release also contains an alpha version of pip's next generation resolver. It is *off by default* because it is *unstable and not ready for everyday use*. If you're curious about this, please read about the resolver, what doesn't work yet, and what kind of testing would help us out: https://github.com/pypa/pip/issues/8099 . Future: We plan to release a version of pip that includes a beta of the new resolver in May: https://pyfound.blogspot.com/2020/03/new-pip-resolver-to-roll-out-this-year.html . And we plan to make our next quarterly release in July 2020. Thanks: As with all pip releases, a significant amount of the work was contributed by pip's user community. Huge thanks to all who have contributed, whether through code, documentation, issue reports and/or discussion. Your help keeps pip improving, and is hugely appreciated. Thank you to the pip and PyPA maintainers, and to all the contributors and volunteers who work on or use Python packaging tools. And thank you to Mozilla (through its Mozilla Open Source Support Awards) and to the Chan Zuckerberg Initiative DAF, an advised fund of Silicon Valley Community Foundation, for funding enabling work on the new resolver, and thanks to the PSF and the Packaging WG for obtaining and administering that funding. best, Sumana Harihareswara project manager for pip, on contract with Python Software Foundation Changeset Consulting, https://changeset.nyc ___ Python-announce-list mailing list -- python-announce-list@python.org To unsubscribe send an email to python-announce-list-le...@python.org https://mail.python.org/mailman3/lists/python-announce-list.python.org/ Member address: arch...@mail-archive.com
Announcement: pip 20.1b1 beta release
On behalf of the Python Packaging Authority, I am pleased to announce that a beta release of pip, pip 20.1b1, has been released. I hope you will help us by testing this and checking for new bugs in how pip deals with complicated projects and dependencies. The highlights for this release are: * Significant speedups when building local directories, by changing behavior to perform in-place builds, instead of copying to temporary directories. * Significant speedups in `pip list --outdated`, by parallelizing network access. This is the first instance of parallel code within pip's codebase. * A new `pip cache` command, which makes it possible to introspect and manage pip's cache directory. * Better `pip freeze` for packages installed from direct URLs, enabled by the implementation of PEP 610. We would be grateful for all the testing that users could do to ensure that, when pip 20.1 is released, it's as solid as we can make it. You can upgrade to this beta with `python -m pip install -U --pre pip`. This release also contains an alpha version of pip's next generation resolver. It is **off by default** because it is **unstable and not ready for everyday use**. If you're curious about this, please visit this GitHub issue about the resolver, what doesn't work yet, and what kind of testing would help us out https://github.com/pypa/pip/issues/8099 .

Fwd: Package maintainers: verify your PyPI account email address
If you maintain any PyPI packages, please verify your address on PyPI. Details below. Forwarded Message Subject: Package maintainers: verify your PyPI account email address Date: Mon, 16 Jul 2018 21:57:38 -0400 From: Sumana Harihareswara To: DistUtils mailing list Heads-up: if you have a pypi.org or test.pypi.org account, please verify your email address: https://pypi.org/manage/account/ https://test.pypi.org/manage/account/ Reason: > We have a problem with a bit of our data, namely that due to historical > reasons we have a fair amount of users in the database that do not have a > verified primary email address. The side effect of this is that we're > currently sending emails to email addresses that we have not had verified. > This is a bad situation to be in, because in order to keep our bounce/spam > rate low, we should be confirming all email addresses before sending email to > them. In addition the way our bounce handling code works is it un-verifies > the email address, which the intent was to stop sending email to it until the > user has reverified their email address. > > In total there are about 193k user accounts with a unverified email address > for their primary address, and 44k that do have a verified email address for > their primary account. > > So we need to come up with a strategy to resolve this, because it's pretty > important that we don't send email to unverified addresses. (quoting from Donald Stufft's explanation https://github.com/pypa/warehouse/issues/3632 which goes on to detail the step-by-step plan) Package maintainers should especially do this soon. As of a few days ago, any user whose primary email address is unverified can't upload a file: https://github.com/pypa/warehouse/pull/4292 Please forward to other package maintainers. After we iron out any issues I figure we'll email the announce list https://mail.python.org/mm3/mailman3/lists/pypi-announce.python.org/ . -- Sumana Harihareswara Changeset Consulting https://changeset.nyc -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
