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 figure folks here might want to try the beta with the Carpentries lessons that involve running pip commands, in case that reveals any bugs in pip or any changes we'll need to make to lessons.
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 * Significant speedups in `pip list --outdated`, by parallelizing network access.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 . The full changelog is available. https://pip.pypa.io/en/latest/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 Awards) and to the Chan Zuckerberg Initiative DAF, an advised fund of Silicon Valley Community Foundation, for their support that enabled the work on the new resolver. -- Sumana Harihareswara pip project manager under contract with Python Software Foundation Changeset Consulting https://changeset.nyc ------------------------------------------ The Carpentries: discuss Permalink: https://carpentries.topicbox.com/groups/discuss/T641ef14422bf15c6-Mf5ed28a529d61ed416632f43 Delivery options: https://carpentries.topicbox.com/groups/discuss/subscription
