Python 3.6.0a1

Python 3.6.0a1 was released on 2016-05-17.

Major new features of the 3.6 series, compared to 3.5

Python 3.6 is still in development; 3.6.0a1 is the first of four planned alpha releases. Alpha releases are intended to make it easier to test the current state of new features and bug fixes and to test the release process. During the alpha phase, features may be added, modified, or deleted up until the start of the beta phase (2016-09-07). Please keep in mind that this is a preview release and its use is not recommended for production environments.

Many new features for Python 3.6 are still being planned and written. Among the new major new features and changes so far:

  • PEP 498, Formatted string literals

The next release of Python 3.6 will be 3.6.0a2, currently scheduled for 2016-06-13.

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 3.6.0a1 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 regarding Embedded Distribution for more information.
  • OS X users: There is important information about IDLE, Tkinter, and Tcl/Tk on Mac OS X here.
