Binary installer support for OS X 10.4 and 10.3.9 to be discontinued

Python 2.7.7 is the last release for which binary installers will be released on python.org that support Mac OS X 10.3.9 (Panther) and 10.4.x (Tiger) systems. For Python 2.7.7 only, we are providing three OS X binary installers: the unchanged 10.6+ 64-bit/32-bit format, the deprecated 10.3+ 32-bit-only format, and the newer 10.5+ 32-bit-only format. See the README included with the installer downloads for more information.

[1](1, 2) The binaries for AMD64 will also work on processors that implement the Intel 64 architecture (formerly EM64T), i.e. the architecture that Microsoft calls x64, and AMD called x86-64 before calling it AMD64. They will not work on Intel Itanium Processors (formerly IA-64).
[2](1, 2, 3) There is important information about IDLE, Tkinter, and Tcl/Tk on Mac OS X here.
