Hash: SHA1

On behalf of the Python development team, I'm delighted to announce the
third release candidate of Python 3.3.0.

This is a preview release, and its use is not recommended in
production settings.

Python 3.3 includes a range of improvements of the 3.x series, as well
as easier porting between 2.x and 3.x.  Major new features and changes
in the 3.3 release series are:

* PEP 380, syntax for delegating to a subgenerator ("yield from")
* PEP 393, flexible string representation (doing away with the
    distinction between "wide" and "narrow" Unicode builds)
* A C implementation of the "decimal" module, with up to 80x speedup
    for decimal-heavy applications
* The import system (__import__) now based on importlib by default
* The new "lzma" module with LZMA/XZ support
* PEP 397, a Python launcher for Windows
* PEP 405, virtual environment support in core
* PEP 420, namespace package support
* PEP 3151, reworking the OS and IO exception hierarchy
* PEP 3155, qualified name for classes and functions
* PEP 409, suppressing exception context
* PEP 414, explicit Unicode literals to help with porting
* PEP 418, extended platform-independent clocks in the "time" module
* PEP 412, a new key-sharing dictionary implementation that
    significantly saves memory for object-oriented code
* PEP 362, the function-signature object
* The new "faulthandler" module that helps diagnosing crashes
* The new "unittest.mock" module
* The new "ipaddress" module
* The "sys.implementation" attribute
* A policy framework for the email package, with a provisional (see
    PEP 411) policy that adds much improved unicode support for email
    header parsing
* A "collections.ChainMap" class for linking mappings to a single unit
* Wrappers for many more POSIX functions in the "os" and "signal"
    modules, as well as other useful functions such as "sendfile()"
* Hash randomization, introduced in earlier bugfix releases, is now
    switched on by default

In total, almost 500 API items are new or improved in Python 3.3.
