If you're curious about the alpha version of pip's new resolver, 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). -- Sumana Harihareswara Changeset Consulting https://changeset.nyc On 4/20/20 10:12 PM, Pradyun Gedam wrote:

On behalf of the PyPA, I am pleased to announce a beta release of pip, pip 20.1b1 has been released.

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 * Significant speedups in `pip list --outdated`, by parallelizing network access.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.

This release also contains an alpha version of pip's next generation resolver. It is *off by default* because it *unstable and notready for everyday use*.

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) <https://www.mozilla.org/en-US/moss/> and to the Chan Zuckerberg Initiative <https://chanzuckerberg.com/eoss/> DAF, an advised fund of Silicon Valley Community Foundation, for their support that enabled the work on the new resolver.

pip 20.1 has been released! You can install it by running `python -m pip install --upgrade pip`. Huge thanks to all who have helped by testing the beta release! During this beta period, we were able to identify and fix regressions as well as improve newly added functionality, based on reports and feedback from our testers. You can find more details in the changelog <https://pip.pypa.io/en/stable/news/>. Cheers, Pradyun On Tue, Apr 21, 2020 at 7:42 AM Pradyun Gedam <pradyunsg@gmail.com> wrote:
