On behalf of the Python development team, I'm delighted to announce the

second 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.

For a more extensive list of changes in 3.3.0, see
