You can download Python 3.6.0 here.  Also, most third-party distributors of Python should be making 3.6.0 packages available soon.

Maintenance releases for the 3.6 series will follow at regular intervals starting in the first quarter of 2017.

We hope you enjoy Python 3.6.0!

P.S. As a volunteer-staffed open source project, we could not bring Python releases to you without the enormous contributions of many, many people.  Thank you to all who have contributed and reviewed code and documentation changes, documented and investigated bugs, tested Python and third-party packages, and provided and supported the infrastructure needed to support Python development and testing.  Please consider supporting the work of the Python Software Foundation.

Beta releases are intended to give the wider community the opportunity
to test new features and bug fixes and to prepare their projects to
support the new feature release. We strongly encourage maintainers of
third-party Python projects to test with 3.6 during the beta phase and
report issues found to bugs.python.org 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 (2016-12-05). Our goal is have no changes
after rc1. To achieve that, it will be extremely important to get as
much exposure for 3.6 as possible during the beta phase. Please keep in
mind that this is a preview release and its use is not recommended for
production environments

The next pre-release of Python 3.6 will be 3.6.0rc1, the release candidate,
currently scheduled for 2016-12-05. The official release of Python 3.6.0
is currently scheduled for 2016-12-16. More information about the release schedule
can be found here:
