Notes on this release

  • 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 3.5.1 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: The OS X installers are now distributed as signed installer package files compatible with the OS X Gatekeeper security feature.
  • OS X users: There is important information about IDLE, Tkinter, and Tcl/Tk on Mac OS X here.
