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 3.5.0b1 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 does not contain Python, but instead downloads just the needed software at installation time.
- Windows users: The Windows binaries were built with Microsoft Visual Studio 2015, which is not yet officially released. (It's currently offered in "Preview" mode, which is akin to a "beta".) It is our intention to ship Python 3.5 using VS2015, although right now VS2015's final release date is unclear.
- 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.
