Python 3.0 Final

Python is an interpreted, interactive, object-oriented programming language often compared to Tcl, Perl, Scheme or Java.

It features modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems (X11, Motif, Tk, Mac, MFC).

New built-in modules are easily written in C or C++. Python is also usable as an extension language for applications that need a programmable interface.

The Python implementation is portable: it runs on many brands of UNIX, on Windows, OS/2, Mac, Amiga, and many other platforms.

What's New in version 3.0:

Core and Builtins:

* Issue #3996: On Windows, the PyOS_CheckStack function would cause the interpreter to abort ("Fatal Python error: Could not reset the stack!") instead of throwing a MemoryError.
* Issue #3689: The list reversed iterator now supports __length_hint__ instead of __len__. Behavior now matches other reversed iterators.
* Issue #4367: Python would segfault during compiling when the unicodedata module couldn't be imported and N escapes were present.
* Fix build failure of _cursesmodule.c building with -D_FORTIFY_SOURCE=2.


Library:

* Issue #4387: binascii now refuses to accept str as binary input.
* Issue #4073: Add 2to3 support to build_scripts, refactor that support in build_py.
* IDLE would print a "Unhandled server exception!" message when internal debugging is enabled.
* Issue #4455: IDLE failed to display the windows list when two windows have the same title.
* Issue #3741: DISTUTILS_USE_SDK set causes msvc9compiler.py to raise an exception.
* Issue #4433: Fixed an access violation when garbage collecting _ctypes.COMError instances.
* Issue #4429: Fixed UnicodeDecodeError in ctypes.
* Issue #4373: Corrected a potential reference leak in the pickle module and silenced a false positive ref leak in distutils.tests.test_build_ext.
* Issue #4382: dbm.dumb did not specify the expected file encoding for opened files.
* Issue #4383: When IDLE cannot make the connection to its subprocess, it would fail to properly display the error message.

Build:

* Issue #4407: Fix source file that caused the compileall step in Windows installer to fail.
