Notes on this release

  • If you are building Python from source, beware that the OpenSSL 1.1.0c release, the most recent as of this update, is known to cause Python 3.6 test suite failures and its use should be avoided without additional patches. It is expected that the next release of the OpenSSL 1.1.0 series will fix these problems. See http://bugs.python.org/issue28689 for more information.
  • 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 regarding Embedded Distribution for more information.
  • macOS users: If you are using the Python 3.6 from the python.org binary installer linked on this page, please carefully read the Important Information displayed during installation; this information is also available after installation by clicking on /Applications/Python 3.6/ReadMe.rtf. There is important information there about changes in the 3.6.0 installer-supplied Python, particularly with regard to SSL certificate validation.
  • macOS users: There is important information about IDLE, Tkinter, and Tcl/Tk on macOS here.
