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* Significant speedups in `pip list --outdated`, by parallelizing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 not
ready 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
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.
