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 3.6.0b4, currently scheduled for 2016-11-21. More information about the release schedule can be found here:
