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
