Beta release of pip version 10

On behalf of the PyPA, I am pleased to announce that a beta release
10.0.0b1 of pip has just been released for testing by the community.
We're planning on a final release in 2 weeks' time, over the weekend
of 14/15 April.

To install pip 10.0.0.b1, you can run

    python -m pip install --upgrade --pre pip

(obviously, you should not do this in a production environment!)

We would be grateful for all testing that users could do, to ensure
that when pip 10 is released it's as solid as we can make it.

Highlights of the new release:

  • Python 2.6 is no longer supported - if you need pip on Python 2.6, you should stay on pip 9, which is the last version to support Python 2.6.
  • Support for PEP 518, which allows projects to specify what packages they require in order to build from source. (PEP 518 support is currently limited, with full support coming in future versions - see the documentation for details).
  • Significant improvements in Unicode handling for non-ASCII locales on Windows.
  • A new "pip config" command.
  • The default upgrade strategy has become "only-if-needed"
  • Many bug fixes and minor improvements.

In addition, the previously announced reorganisation of pip's
internals has now taken place. Unless you are the author of code that
imports the pip module (or a user of such code), this change will not
affect you. If you are, please report the issue to the author of the
affected code (refer them to
for the details of the announcement).

Please note that there is a minor issue with the NEWS file for this
release - the new features in 10.0.0b1 are reported as being for
"9.0.3 (2018-03-31)".

If you discover any bugs while testing the new release, please report
them at

Thanks to everyone who put so much effort into the new release. Many
of the contributions came from community members, whether in the form
of code, participation in design discussions, or bug reports. The pip
development team is extremely grateful to everyone in the community
for their contributions.

Python 3.7.0b3 is now available for testing

Python 3.7.0b3 is the third of four planned beta previews of Python 3.7, the next feature release of Python. Beta releases are intended to give you the opportunity to test new features and bug fixes and to prepare your projects to support the new feature release. We strongly encourage you to test your projects with 3.7 during the beta phase and report issues found to as soon as possible. While the release is feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase.  Please keep in mind that this is a preview release and its use is not recommended for production environments.  Attention macOS users: there is now a new installer variant for macOS 10.9+ that includes a built-in version of Tcl/Tk 8.6. This variant is expected to become the default version when 3.7.0 releases.  Check it out! The next preview release, 3.7.0b4, is planned for 2018-04-30. You can find Python 3.7.0b3 and more information here:

The all new Python Package Index is now in beta at

The new Python Package Index at is now in beta.

This means the site is robust, but we anticipate needing more user testing and changes before it is "production-ready" and can fully replace . We hope to complete the transition before the end of April 2018.

We're still working to ensure the new codebase and infrastructure are reliable. So please don't rely on it (yet) unless you can handle the occasional minor outage.

But we want you to try the new PyPI, test it, and tell us if you have any problems. More at The Python Software Foundation main blog.

Thank you.
