On behalf of the Python development team, I'm chuffed to announce the second alpha release of Python 3.4. This is a preview release, and its use is not recommended for production settings. Python 3.4 includes a range of improvements of the 3.x series, including hundreds of small improvements and bug fixes. Major new features and changes in the 3.4 release series so far include: * PEP 435, a standardized "enum" module * PEP 442, improved semantics for object finalization * PEP 443, adding single-dispatch generic functions to the standard library * PEP 445, a new C API for implementing custom memory allocators * PEP 446, changing file descriptors to not be inherited by default in subprocesses * PEP 447, a new magic method for metaclasses (``__typelookup__``) * PEP 448, making automatic sequence unpacking more general To download Python 3.4.0a2 visit: http://www.python.org/download/releases/3.4.0/ Please consider trying Python 3.4.0a2 with your code and reporting any issues you notice to: http://bugs.python.org/ Enjoy! -- Larry Hastings, Release Manager larry at hastings.org (on behalf of the entire python-dev team and 3.4's contributors)

Those last two PEPs are still in draft form and not accepted nor have any committed code yet.

* PEP 446, changing file descriptors to not be inherited by default in subprocesses
The title of the PEP is "Make newly created file descriptors non-inheritable". It has an impact on all functions creating files and sockets not only the subprocess module. You can also add a link to the nice What’s New In Python 3.4 document: http://docs.python.org/dev/whatsnew/3.4.html Victor

Yay! 3.4.0a2 also contains a new batteries-included feature for OS X users. The python.org 64-bit/32-bit installer now includes its own private version of Tcl/Tk 8.5.14 so it is finally no longer necessary to install a third-party version of Tcl/Tk 8.5 to workaround the problematic system versions shipped in OS X 10.6+. More improvements to come. -- Ned Deily, nad@acm.org

With MS Windows on steep decline, I'm so happy we have at least MacOS-X rising to keep us busy. Stefan

MS Windows is on a steep decline? I mean, I know Windows 8 isn't the most popular thing on the planet, but...Windows itself? If anything would be rising, I'd still prefer it to be either Linux or Haiku. On Tue, Sep 10, 2013 at 12:48 AM, Stefan Behnel <stefan_ml@behnel.de> wrote:
