    Please seeWhat’s New In Python 3.6 for more information.Additional documentation for these features and other changes will be updated during the beta phase.

    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 was 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 for2016-11-21.

    Notes on this release

    • Windows users: The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the "x64" architecture, and formerly known as both "EM64T" and "x86-64".) They will not work on Intel Itanium Processors (formerly "IA-64").
    • Windows users: If installing Python 3.6.0 as a non-privileged user, you may need to escalate to administrator privileges to install an update to your C runtime libraries.
    • Windows users: There are now "web-based" installers for Windows platforms; the installer will download the needed software components at installation time.
    • Windows Users: There are redistributable zip files containing the Windows builds, making it easy to redistribute Python as part of another software package. Please see the documentation regardingEmbedded Distribution for more information.
    • OS X users: There isimportant information about IDLE, Tkinter, and Tcl/Tk on Mac OS X here.
