[Python-Dev] [RELEASED] Python 3.3.0

[Georg Brandl]

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

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 120x 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

Agreed - this is a really nice release, thanks to all who put it together.

Congrats Georg and team! I am incredibly proud of you all for
producing such a great release. As the marketeers would say, "Python
3.3 is the best Python ever!" The feature list is amazing.

Hello,

I've created a 3.3 category on the buildbots:
http://buildbot.python.org/3.3/
http://buildbot.python.org/3.3.stable/

Someone will have to update the following HTML page:
http://python.org/dev/buildbot/

Regards

Antoine.

Reading this to see if I missed anything while downloading the new release:

I found:

For the common user, this change should result in no visible change in semantics. Any possible changes required in one’s code to handle this change should read the Porting Python code section of this document to see what needs to be changed, but it will only affect those that currently manipulate import or try calling it programmatically.

Sentence two in this paragraph has bizarre structure, probably due to being changed from one perspective to another.  Suggestion (which turns out to be briefer):

For the common user, this change should result in no visible change in semantics. Any code changes required are described in the Porting Python code section of this document; it will only affect code that currently manipulates import or calls it programmatically.

I fixed this, though with a different wording change.

Thanks. It's really a team effort: a little digging in the hg history says
that:

* 86 people have committed during the 3.3 development
* 70 during 3.2 development and
* 55 during 3.1 development

No surprise the feature list is so long...

cheers,
Georg

Many kudos to the team and to all contributors!

Linux Weekly News regularly publishes tables "Who done what in Linux
Kernel": http://lwn.net/Articles/507986/
http://lwn.net/SubscriberLink/517564/bec11e6ace6ad699/

It would be interesting to see tables like these for Python.

Programmers don't die, they just GOSUB without RETURN.
